The variable is Z is inversely proportional to X. When X is 6, Z has the value 0.5. What is the value of Z when X = 10

Answers

Answer 1

given that z is inversely proportional to x, then:
zα1/x
hence;
z=k/x
where k is the constant of proportionality;
this implies that:
k=xz
when x=6,z=0.5
thus;
k=0.5*6
k=3
hence;
z=3/x
when x=10,
z=3/10
the answer is 3/10

How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?

Answers

The graph has been moved 3 units downward, making the range change. The range of f(x) is [-5,5], while the range of g(x) is [-8,2]. The picture is of both functions. f(x) is blue, g(x) is red.

Answer:

[-8,2]

Step-by-step explanation:

We are given that the function f(x) is transformed to the function g(x), where,

[tex]f(x) =-5 \cos 2x[/tex] and [tex]g(x) =-5 \cos 2x-3[/tex].

Since, the range of [tex]\cos x[/tex] is [-1,1].

Thus, the range of [tex]a\cos bx[/tex] is {-a,a].

So, the range of [tex]f(x) =-5 \cos 2x[/tex] is [-5,5].

As, we are translating the function f(x) 3 units downward to get g(x).

The graph of the function is shifted 3 units down.

So, the range of g(x) will be [-5-3,5-3] = [-8,2].

Hence, the range of [tex]g(x) =-5 \cos 2x-3[/tex] is [-8,2].

Indicate in standard form the equation of the line passing through the given points. R(3, 3), S(-6, -6)

Answers

First find slope....

slope=m=(y2-y1)/(x2-x1)

m=(-6-3)/(-6-3)

m=-9/-9

m=1

Point slope form is y-y1=m(x-x1) where m=slope and (x1,y1) is any point on the line so using m=1 and (3,3) we have:

y-3=x-3 but the standard form is ax+by=c so we need to solve for the constant...

y-3=x-3 subtract x from both sides

y-x-3=-3 add 3 to both sides

y-x=0 and x should have a positive coefficient...divide both sides by -1

x-y=0

Answers

Calculate first the area of the shaded triangle region and the area of the square then you could get the probability of the point
The formula for the area of triangle is b h / 2
Where:b = h = half of side length of square = 9 mm
Area of triangle = 9 mm * 9 mm / 2
Area of triangle = 40.5 mm^2

Area of square = s^2
Area of square = (18 mm)^2
Area of square = 324 mm^2

the exterior angle of a regular polygon is equal to one third of the interior angle. calculate the number of sides of the polygon and give its name

Answers

The angle in a regular polygon is ((n-2)*180)/n with n being the number of sides. The exterior angles would be (360)/n since exterior angles add up to 360. Therefore, (360)/n= (((n-2)*180)/n)*1/3. Multiplying both sides by n, we get 360=((n-2)*180)*1/3. After that, we divide both sides by 180 and multiply both sides by 3 to get 6=n-2. Therefore, n=8 and it is an octagon

The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight of each tire in pounds? There are 453.592 grams in one pound. Round answers to 2 decimal places.

Answers

Answer:

800 is 1.74

700 is 1.54

Step-by-step explanation:

i just took the assignment and it was right

The weight of each tire in pounds is 1.76 pounds for the full steel bead tire and 1.54 pounds for the lighter wheel.

To find the weight of each tire in pounds, we'll first convert the weights from grams to pounds using the conversion factor provided (1 pound = 453.592 grams). Then, we'll round the answers to two decimal places.

Let's denote:

Weight of full steel bead tire = 800 grams

Weight of lighter wheel = 700 grams

Convert the weight of the full steel bead tire from grams to pounds:

[tex]$800 \, \text{grams} \times \frac{1 \, \text{pound}}{453.592 \, \text{grams}} = 1.763698 \, \text{pounds}$[/tex]

Rounded to two decimal places, the weight of the full steel bead tire is approximately 1.76 pounds.

Convert the weight of the lighter wheel from grams to pounds:

[tex]$700 \, \text{grams} \times \frac{1 \, \text{pound}}{453.592 \, \text{grams}} = 1.543235 \, \text{pounds}$[/tex]

Rounded to two decimal places, the weight of the lighter wheel is 1.54 pounds.

So, the weight of each tire in pounds is 1.76 pounds for the full steel bead tire and 1.54 pounds for the lighter wheel.

The width of a rectangle is one half it's length. The perimeter of the rectangle is 54 cm. What are the width and length of the rectangle?

Answers

width= 1/2x length=x
to find the perimeter, it's the width+width+length+length so:
1/2x+1/2x+x+x=54
3x=54
x=18
the length is 18 cm and the width is 9 cm

Let length of the rectangle = x.
Let width of the rectangle = x/2 (or 1/2 of x)

Remember that Area = 2L + 2W, so . . .

2x + 2(x/2) = 54

2x + (2/2)x = 54

2x + x = 54

3x = 54 --> x = 54/3 --> x = 18

So the length of the rectangle is 18 cm and the width is 18/2 = 9 cm.

Two points in the xy plane have cartesian coordinates (2.00, 24.00) m and (23.00, 3.00) m. determine (a) the distance between these points and (b) their polar coordinates

Answers

Final answer:

The distance between the two points is approximately 29.70 m. The polar coordinates of the points are approximately (24.20 m, 1.46 radians).

Explanation:

To find the distance between two points in the Cartesian coordinate plane, we can use the distance formula.

The distance between the points (2.00, 24.00) m and (23.00, 3.00) m is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values, we get:

d = sqrt((23.00 - 2.00)^2 + (3.00 - 24.00)^2)

d = sqrt(441 + 441)

d = sqrt(882)

d ≈ 29.70 m

The polar coordinates of a point (x, y) can be found using the formulas:

r = sqrt(x^2 + y^2)

p = atan2(y, x)

Plugging in the values, we get:

r = sqrt(2.00^2 + 24.00^2)

p = atan2(24.00, 2.00)

r ≈ 24.20 m

p ≈ 1.46 radians

Answers

Because x is not defined, it is assumed to be the height of the balloon.

Note that
75° 20' = 75.333°
49° 30' = 49.5°

From the figure shown below, obtain by definition,
a = x cot 49.5° = 0.8541x
b = x cot 75.333° = 0.2617x

Because a + b = 400 ft, therefore
