Here,
the initial point of vector u(x1,y1)=(-7,2)
the final point of vector u (x2,y2)=(11,5)
so the component of vector u(x,y)=(x2,y2)-(x1,y1)
=(11+7,5-2)=(18,3)
according to the question, the magnitude of vector is thrice the magnitute of vector u and is opposite ot the ditecrion of vector u.
so the component of vector v is -3(x,y)
=-3(18,3)=(-54,-9)
Tim throws a stick straight up in the air from the ground. The function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?
The inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet is -[tex]16t^2 + 48t > 8[/tex]
To solve this inequality, let's rearrange it:
-[tex]16t^2 + 48t - 8 > 0[/tex]
Now, we have a quadratic inequality. To solve it, we'll first find the critical points by setting the expression equal to zero:
[tex]-16t^2 + 48t - 8 = 0[/tex]
Now, we'll use the quadratic formula to find the roots:
[tex]t = [ -b ± √(b^2 - 4ac) ] / (2a)[/tex]
Where a = -16, b = 48, and c = -8.
Plugging in these values, we get:
[tex]t = [ -48 ± √(48^2 - 4(-16)(-8)) ] / (2(-16))[/tex]
[tex]t = [ -48 ± √(2304 - 512) ] / (-32)[/tex]
[tex]t = [ -48 ± √(1792) ] / (-32)[/tex]
[tex]t ≈ [ -48 ± 42.35 ] / (-32)[/tex]
Now, we have two critical points:
t1 ≈ (-48 + 42.35) / (-32) ≈ 0.186
t2 ≈ (-48 - 42.35) / (-32) ≈ 2.814
Now, we'll test intervals between and outside these critical points to determine when the inequality is satisfied:
For t < 0.186: The quadratic term dominates, leading to a negative value.
For 0.186 < t < 2.814: The quadratic term dominates, leading to a positive value.
For t > 2.814: The linear term dominates, leading to a negative value.
So, the solution to the inequality is 0.186 < t < 2.814.
Thus, the stick reaches a height of more than 8 feet between approximately 0.186 seconds and 2.814 seconds.

A group of people were given a personality test to determine if they were Type A or Type B. The results are shown in the table below: Male Female Type A 65 85 Type B 38 12 Compare P(Male or Type B) with P(Male | Type B). P(Male or Type B) > P(Male | Type B) P(Male or Type B) = P(Male | Type B) P(Male or Type B) < P(Male | Type B) There is not enough information.
Answer:
P(Male or Type B) > P(Male | Type B)
Step-by-step explanation:
Total Female = 85 type A, 12 type B ⇒ 97 Female.
Total Male = 65 type A, 38 type B ⇒ 103 Male
Total type A = 65 + 85 = 150
Total type B = 12 + 38 = 50
total number of people = 97 + 103 = 200
Then the probability would be:
P(Male | Type B) = [tex]\frac{number of male in B}{total number of male}[/tex]
= [tex]\frac{38}{103}[/tex]
= 0.368
P(Male or Type B) = [tex]\frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}[/tex]
= [tex]\frac{103 + (50 - 38)}{200}[/tex]
= [tex]\frac{103 + 12}{200}[/tex]
= [tex]\frac{115}{200}[/tex]
= 0.575
Hence, P(Male or Type B) > P(Male | Type B)

Answer:
z = 99°
Step-by-step explanation:
y = 0.5 × 96° = 48° ( inscribed angle subtended on same arc )
x = 0.5 × 66° = 33° ( inscribed angle subtended on same arc )
The sum of the 3 angles in the triangle = 180°, hence
third angle = 180° - (48 + 33)° = 180° - 81° = 99°
z = 99° ( vertical angle )
Check
96° + 99° + 66° + 99° = 360°

The area of the base of a rectangular prism is 36 cm2. The height of the prism is 3 5 6 cm. What is the volume of the prism?
Answer:
138 cm³
Step-by-step explanation:
Given in the question that base of the rectangular prism = 36 cm²
Height of the prism = 3 5/6 cm = 23/6
We know that the volume of a rectangular prism with base area B and height H is given by
Volume = B(H)Plug values in the formula above to find the volume of the prism
Volume = 36(23/6)
= 6(23)
= 138 cm³
So the volume of prism = 138 cm³
Answer:
108 cm³, 138 cm³, 180 cm³, 216 cm³
Step-by-step explanation:
I'm not if you meant to calculate three possible volumes for the prism, for heights of 3, 5 and 6 cm or if it was meant as 3 5/6... so I prepared you all the answers below.
Normally, the volume of a prism is calculated with Length x Width x Height. The (Length x Width) part is form the base of the prism. Since we already have that base measurement, we'll use the formula: Base x Height
So, if you meant 3 different calculations (for heights 3, 5 and 6 cm):
V = Base x Height
For a height of 3 cm, we have: V = 36 x 3 = 108 cm³
For a height of 5 cm, we have: V = 36 x 5 = 180 cm³
For a height of 6 cm, we have: V = 36 x 6 = 216 cm³
If however, you meant a single measure with 3 5/6:
For a height of 3 5/6 cm (23/6), we have: V = 36 x 23/6 = 6 * 23= 138 cm³

C. m<EGC = 120°
D. m<GCB + m<CBE = 180°
E. m<BEG + m<EGC = 230°
F. The sum of all exterior angles of BEGC is equal to 360°.
Answer:
The sum of all exterior angles of BEGC is equal to 360° ⇒ answer F only
Step-by-step explanation:
* Lets revise some facts about the quadrilateral
- Quadrilateral is a polygon of 4 sides
- The sum of measures of the interior angles of any quadrilateral is 360°
- The sum of measures of the exterior angles of any quadrilateral is 360°
* Lets solve the problem
- DEGC is a quadrilateral
∵ m∠BEG = (19x + 3)°
∵ m∠EGC = (m∠GCB + 4x)°
∵ The sum of the measures of its interior angles is 360°
∴ m∠BEG + m∠EGC + m∠GCB + m∠CBE = 360
∴ (19x + 3) + (m∠GCB + 4x) + m∠GCB + m∠CBE = 360 ⇒ add the like terms
∴ (19x + 4x) + (m∠GCB + m∠GCB) + m∠CBE + 3 = 360 ⇒ -3 from both sides
∴ 23x + 2m∠GCB + m∠CBE = 375
∵ The sum of measures of the exterior angles of any quadrilateral is 360°
∴ The statement in answer F is only true

A sphere has a radius of 15 m. If the radius is divided by 5, what is the effect on the surface area? HELP PLEASE!!
i got 3 and the teacher said it was right
Answer:
The surface area is divided by 25.
Step-by-step explanation:
The radius of a sphere is given as 15 m.
To obtain the surface area of the original sphere, substitute the radius length into the formula for the surface area of a sphere, S=4πr2.
S=4π(15)2=(4)(225)π=900π
The surface area of the original sphere is 900π m2.
To find the radius of the new sphere divide the radius of the original sphere by 5.
r=155=3
The radius of the new sphere is 3 m.
To obtain the surface area of the new sphere, substitute the radius length into the formula for the surface area of a sphere, S=4πr2.
S=4π(3)2=(4)(9)π=36π
The surface area is 36π m2.
Notice that 900π=25(36π). The surface area of the second sphere is 52=25 times less than the original surface area. The surface area of a sphere changes by the square of the factor that the radius changes.
Therefore, the surface area is divided by 25.
Determine whether the sequence is arithmetic, geometric, both, or neither. 1, 4, 9, 16, 25, . . .
Answer:
neither
Step-by-step explanation:
First differences are 3, 5, 7, 9, and the differences of these (2nd differences) are constant at 2. The degree of the polynomial function describing the sequence is equal to the number of the differences that are constant. Here, that is 2nd differences, so the sequences is described by a 2nd-degree (quadratic) polynomial.
It is not linear (arithmetic) or exponential (first differences have a common ratio).

Janet can do a job in 3 hours while Garry can do the same job in 2 hours. If Janet works for an hour before Garry began helping her, how long will it take them to finish the job together?
Answer:
4/5 hour (48 minutes)
Step-by-step explanation:
Janet works at the rate of ...
(1 job)/(3 hours) = (1/3) job/hour
So, in 1 hour, she has worked 1/3 of the job, leaving 2/3 of the job remaining when Garry shows up.
Garry works at the rate of ...
(1 job)/(2 hours) = 1/2 job/hour
So, together they work at the rate of ...
(1/3 job/hour) + (1/2 job/hour) = (2/6 +3/6) job/hour = 5/6 job/hour
Then the time it takes to do the remaining 2/3 job is ...
(2/3 job)/(5/6 job/hour) = (2/3·6/5) hour = 4/5 hour
It will take 4/5 hour for them to finish the job together.
Answer: 4/5 of an hour or 48 minutes
Step-by-step explanation:
Janet's Rate : 1 job / 3 hours = 1/3 job/hour
In 1 hour, 1/3 of the job is already finished by her, so there is 2/3 of the job left.
Garry's Rate:
1 job / 2 hours = 1/2 job/hour
Janet an Garry's Rate:
1/3 job/hour + 1/2 job/hour = 2/6 +3/6 job/hour = 5/6 job/hour
Time to do remaining 2/3 of job:
2/3 job / 5/6 job/hour = 2/3 * 6/5 hour = 4/5 hour
Answer:
It will take 4/5 of an hour for them to finish the job together.

A rectangular prism with a volume of 5 cubic units is filled with cubes with side lengths of 1/3 units. How many 1/3 ?unit cubes does it take to fill the prism?
Answer:
135
Step-by-step explanation:
The little cubes with side length 1/3 unit have volume (1/3 unit)³ or (1/27 unit)³. Divide the prism volume (5 units³) by (1/27 units³) to determine how many little cubes are required to fill the prism:
5 units³
--------------- = 135 little cubes.
1/27 unit
Note: This assumes that the dimensions of the prism are such that there is no wasted space when all these little cubes are packed inside. For example, if the width of the prism were 3, then we assume that 3 little cubes would fit that particular dimension.
There are 135 cubes in the cube with a volume of 5 cubic units and the small cube has a side length of 1/3 unit.
What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
As we know, the volume of the cube = side³
The volume of the rectangular prism = 5 cubic units
The volume of the small cube with side lengths of 1/3 unit is:
= (1/3)×(1/3)×(1/3)
= 1/27
The number of cubes in the big cube = 5/(1/27)
= 5×27
= 135 cubes
Thus, there are 135 cubes in the cube with a volume of 5 cubic units and the small cube has a side length of 1/3 unit.

b.) Use the formula to predict the rice weevil population 10 weeks after the beginning of the study. Show your work.
c.) Use the formula to predict when the rice weevil population will reach 1,000,000,000. Show your work.
Answer:
Part a) [tex]y=400(2.5)^{x}[/tex]
Part b) [tex]3,814,697\ rice\ weevil\ population[/tex]
Part c) [tex]16.1\ weeks[/tex]
Step-by-step explanation:
Part a) Write and simplify a formula that can be used to predict the rice weevil population for any week after the beginning of the study
we know that
100%+150%=250%=250/100=2.5
In this problem we have an exponential function of the form
[tex]y=a(b)^{x}[/tex]
where
a is the initial value
b is the base
y ----> is the rice weevil population
x ----> the number of weeks
In this problem
a=400 rice weevils
b=2.5
substitute
[tex]y=400(2.5)^{x}[/tex]
Part b) Use the formula to predict the rice weevil population 10 weeks after the beginning of the study. Show your work
we have
[tex]y=400(2.5)^{x}[/tex]
so
For x=10 weeks
substitute
[tex]y=400(2.5)^{10}=3,814,697\ rice\ weevil\ population[/tex]
Part c) Use the formula to predict when the rice weevil population will reach 1,000,000,000.
we have
[tex]y=400(2.5)^{x}[/tex]
so
For y=1,000,000,000 rice weevil population
substitute in the formula and solve for x
[tex]1,000,000,000=400(2.5)^{x}[/tex]
Simplify
[tex]2,500,000=(2.5)^{x}[/tex]
Apply log both sides
[tex]log(2,500,000)=x*log(2.5)[/tex]

A function assigns the values. The number of weeks it will take for the population of 400 to be 1,000,000,000 is 16.1 weeks.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A.) Given there are 400 rice weevils at the beginning. And the population is expected to grow at a rate of 150% each week. Therefore, the function that can represent the population can be written as,
Population after n weeks = 400×(1+1.5)ⁿ = 400×(2.5)ⁿ
where n is the number of weeks.
B.) The population of the rice weevils after 10 weeks will be,
Population after 10 weeks = 400×(2.5)¹⁰ = 3,814,697.266 ≈ 3,814,697
C.) The time needed for the population to reach 1,000,000,000 will be,
1,000,000,000 = 400(2.5)ⁿ
2,500,000 = 2.5ⁿ
n = 16.0776 ≈ 16.1 weeks
Hence, the number of weeks it will take for the population of 400 to be 1,000,000,000 is 16.1 weeks.

The area of the right triangle shown is 24 square feet. Which equations can be used to find the lengths of the legs of the triangle? Check all that apply. a x2 + 2x – 24 = 0 b x(x + 2) = 24 c x2 + (x + 2)2 = 100 d 0.5(x)(x + 2) = 24 e x2 + 2x – 48 = 0 f x2 + (x + 2)2 = 24
Given : A = 24 sq feet
A = 0.5 base x height
base = x , height = x+2
A = 0.5 x(x+2) = 24 sq feet
1) 0.5 x(x+2) = 24 (A)
2) x^2 + 2x - 48 = 0 (D)
To check the rest un-wrap the bracket:
x^2 + (x+2)^2 = 24
x^2 + x^2 + 4 + 4x = 24
2x^2 + 4x - 20 = 0
x^2 + 2x - 10= 0 (NO)
Likewise:
x^2 + (x+2)^2 = 100
x^2 + x^2 +4 + 4x = 100
2x^2 + 4x + 4 = 100
2x^2 + 4x - 96 = 0
3) x^2 + 2x - 48 = 0 (F)
To sum up: that's what apply:
1) 0.5 x(x+2) = 24 (A)
2) x^2 + 2x - 48 = 0 (D)
3) x^2 + 2x - 48 = 0 (F)
