You just have to split the figures in different parts...

- First Picture:

- the total length is 130, so the upper and bottom rectangles have 50ft. as showed, and the middle one is 130-(50x2) = 30

- The second step is get the 2 holes área to subtract from the “total rectangle without holes area” (30x40=1200)x2 and then (20,150-1400=18,750) so, the total area from the rectangle with the holes is 18,750!

ANSWER

B. A(x)=0.5 (f .g)(x)

EXPLANATION

The area of a triangle is calculated using the formula:

Area=0.5 Base × Height

The base is given by

g(x)=2x

and the height of the function is

[tex]f(x)= {x}^{2} + 3[/tex]

This implies that:

A(x)=0.5f(x) × g(x)

A(x)=0.5 (f .g)(x)

Answer:

The solutions are (6,13) and (1,3)

Step-by-step explanation:

We want to solve

[tex]y=x^2-5x+7[/tex]

and

[tex]y=2x+1[/tex]

We equate both equations to get:

[tex]x^2-5x+7=2x+1[/tex]

[tex]x^2-5x-2x+7-1=0[/tex]

[tex]x^2-7x+6=0[/tex]

We split the middle term to get:

[tex]x^2-6x-x+6=0[/tex]

[tex]x(x-6)-1(x-6)=0[/tex]

[tex](x-6)(x-1)=0[/tex]

[tex](x-6)=0,(x-1)=0[/tex]

[tex]x=6,x=1[/tex]

When x=6, y=2(6)+1=13

When x=1, y=2(1)+1=3

Answer:

y intercept is 1/3

Step-by-step explanation:

[tex]f(x)=-\frac{2}{9} x+ \frac{1}{3}[/tex]

To find y intercept we plug in 0 for x

Y intercept point is a point where the graph f(x) crosses y axis.

At y intercept, the value of x is 0

to find y intercept we plug in 0 for x

[tex]f(0)=-\frac{2}{9} (0)+ \frac{1}{3}[/tex]

Answer:

Option 1: 0.32

Step-by-step explanation:

Let

P(A) be the experimental probability of getting two

And

P(B) be the experimental probability of getting three

The dice is rolled 360 times.

So the sample space is n(S) = 360

P(A) = n(A)/n(S)

= 54/360

= 0.15

And

P(B) = n(B)/n(S)

= 62/360

= 0.172

As both the events A and B are mutually exclusive,

P(A or B)  = P(A) + P(B)

= 0.15 + 0.172

=0.322

Rounding of to one decimal gives us:

0.32

So the probability of rolling a two or three is 0.32 ..

Answer:

16 m < P < 19 m

Step-by-step explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x----> the length of the third side

Applying the triangle inequality theorem

1) 3+8 > c

11 > c

c < 11 m

2) c+3 > 8

c> 5 m

so

the measure of the third side must be

5 m < c < 8 m

therefore

The perimeter of the triangle is equal to

P=3+8+c

P=11+c

The inequality is equal to

(11+5) m < P < (11+8) m

16 m < P < 19 m

Answer:

-6.

Step-by-step explanation:

y = x - 6

Step-by-step explanation:

Answer:

The longest bread stick is approximately 16 in

Explanation:

The diagram representing the tray is shown in the attached image

From the diagram, we can note that the diagonal of the tray represents the hypotenuse of a right-angled triangle having legs 9.5 in and 13 in

Therefore, to get the length of the hypotenuse, we can use the Pythagorean equation which is as follows:

c² = a² + b²

where c is the length of the hypotenuse and a and b are the length of the two legs

Substitute with the givens in the above equation to get the length of the hypotenuse as follows:

c² = (9.5)² + (13)² = 259.25

c = 16.1 in which is approximately 16 in

From the above, we can conclude that:

The longest bread stick that can be fit straight along the diagonal of the tray is approximately 16 in

Answer:

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

x ----> the area of the enlarged garden

y ----> the area of the original garden

[tex]z^{2}=\frac{x}{y}[/tex]

we have that

If Tessa multiplies each dimension by 2, then the scale factor equals 2.

[tex]z=2[/tex]

substitute

[tex]2^{2}=\frac{x}{y}[/tex]

[tex]4=\frac{x}{y}[/tex]

[tex]x=4y[/tex]

The area of the enlarged garden will be equal 4 times the area of the original garden

so

If Tessa wanted to have twice as much surface, she must multiply each dimension by a square root of 2.

therefore

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two.

Answer:

19) sin 48° ≅ 0.7431

20) sin 38° ≅ 0.6157

21) cos 61° ≅ 0.4848

22) cos 51° ≅ 0.6293

Step-by-step explanation:

* Lets explain the meaning of trigonometry ratio

- In any right angle triangle:

# The side opposite to the right angle is called the hypotenuse

# The other two sides are called the legs of the right angle

* If the name of the triangle is ABC, where B is the right angle

∴ The hypotenuse is AC

∴ AB and BC are the legs of the right angle

- ∠A and ∠C are two acute angles

- For angle A

# sin(A) = opposite/hypotenuse

∴ sin(A) is the ratio between the opposite side of ∠A and the hypotenuse

# cos(A) = adjacent/hypotenuse

∴ cos(A) is the ratio between the adjacent side of ∠A and the hypotenuse

# tan(A) = opposite/adjacent

∴ tan(A) is the ratio between the opposite side of ∠A and the

  adjacent side of A

# The approximation to the nearest ten-thousandth, means look to

  the fifth number before the decimal point if its 5 or greater than 5

  ignore it and add the fourth number (ten-thousandth) by 1 if it is

 smaller than 5 ignore it and keep the fourth number as it

* Now lets solve the problems

19) sin 48° is the ratio between the side opposite to the angle of

    measure 48° and the hypotenuse of the triangle

∴ sin 48° = 0.74314 ≅ 0.7431 ⇒ to the nearest ten-thousandth

20) sin 38° is the ratio between the side opposite to the angle of

    measure 38° and the hypotenuse of the triangle

∴ sin 38° = 0.61566 ≅ 0.6157 ⇒ to the nearest ten-thousandth

21) cos 61° is the ratio between the side adjacent to the angle of

    measure 61° and the hypotenuse of the triangle

∴ cos 61° = 0.48480 ≅ 0.4848 ⇒ to the nearest ten-thousandth

22) cos 51° is the ratio between the side adjacent to the angle of

    measure 51° and the hypotenuse of the triangle

∴ cos 51° = 0.62932 ≅ 0.6293 ⇒ to the nearest ten-thousandth

Answer:

Yes, (0,4) is a solution

Step-by-step explanation:

We have to plug in 0 in x and 4 in y IN BOTH THE INEQUALITIES.

IF BOTH ARE TRUE, then the system of inequalities is TRUE.

Let's check:

y ≤ -3x+4

4 ≤ -3(0)+4

4 ≤ 4

Is 4 less than OR equal to 4? Yes. THis is satisfied.

Now, checking 2nd one:

y > x^2 + 3x - 2

4 > (0)^2 + 3(0) - 2

4 > -2

Is 4 greater than -2? Yes, it is. So this is satisfied as well.

Hence, (0,4) is a solution to the system of inequalities shown.

Answer:

Yes, it is the solution

Step-by-step explanation:

You are given the system of two inequalities

[tex]\left\{\begin{array}{l}y\le -3x+4\\ \\y>x^2+3x-2\end{array}\right.[/tex]

To check whether point (0,4) is the solution to this system, substitute x=0 and y=4 into each inequality:

1.

[tex]4\le -3\cdot 0+4\\ \\4\le 4 \ [\text{true}][/tex]

2.

[tex]4>0^2+3\cdot 0-2\\ \\4>0+0-2\\ \\4>-2\ [\text{true}][/tex]

Since the coordinates of the point (0,4) satisfy both inequalities, the point (0,4) is the solution to the system

ANSWER

[tex]f( - 3) = - \frac{9 }{7} [/tex]

EXPLANATION

The given function is

[tex]f(x) = \frac{2 {x}^{2} }{3x - 5} [/tex]

We want to find f(-3)

We substitute x=-3 into the function to get;

[tex]f( - 3) = \frac{2 {( - 3)}^{2} }{3( - 3) - 5} [/tex]

Simplify;

[tex]f( - 3) = \frac{2 \times 9 }{ - 9- 5} [/tex]

[tex]f( - 3) = - \frac{18 }{ 14} [/tex]

[tex]f( - 3) = - \frac{9 }{7} [/tex]

Answer: No, his prediction is unreasonable. After 5 minutes, the number of cells would be 400, not 32. See the explanation below for details.

-------

Remember:

-------

Identify the given information.

[tex]a_{1}[/tex] = 25

[tex]r[/tex] = 2

Use the explicit formula for geometric sequences.

[tex]a_{n} = a_{1} r^{n - 1}[/tex]

Substitute the given values.

[tex]a_{n} = (25)(2)^{n - 1}[/tex]

Substitute in 5 for [tex]n[/tex] to find out how many cells there would be after 5 minutes.

[tex]a_{5} = (25)(2)^{5 - 1} \\\\a_{5} = (25)(2)^{4} \\\\a_{5} = (25)(16)\\\\a_{5} = 400[/tex]

Final answer:

The doctor's prediction of 32 cells after 5 minutes is not reasonable, because based on exponential growth of doubling every minute, 25 initial cells should grow to 800 cells in that time period.

Explanation:

The given question involves the calculation of cell numbers in a growing population, which relates to the field of exponential growth. Using the information provided that the number of cells doubles every minute, we can apply the formula for exponential growth, which is [tex]2^{n}[/tex], where 'n' is the number of generations or minutes in this case.

Starting with 25 cells, after 5 minutes, the expected number of cells would be calculated by multiplying 25 by 25 (since the cells double every minute). This calculation gives us 25 * 32, which equals to 800 cells after 5 minutes. Therefore, the doctor's prediction that there would only be 32 cells after 5 minutes is not reasonable, as the correct calculation suggests the number should be much higher.

Answer:

[tex]2x^\frac{5}{3} - 4y^\frac{3}{4}[/tex]

Step-by-step explanation:

Given equation:

[tex]\sqrt[3]{8x^5} - \sqrt[4]{256y^3}[/tex]

([tex](8x^5)^\frac{1}{3} - (256y^3)^\frac{1}{4} \\ (8^\frac{1}{3}  . x^\frac{5}{3} ) - (256^\frac{1}{4}. y^\frac{3}{4})\\ 2x^\frac{5}{3} - 4y^\frac{3}{4}[/tex] !

The initial equations of (3√8x^5) and (4√256y^3) are first changed to exponential form and then simplified to final forms of 6x^2√x and 64y respectively. The final simplified form of the entire equation therefore becomes 6x^2√x - 64y.

The given expression is (3√8x^5) - (4√256y^3). Lets breakdown and simplify each component firstly.

The first expression, 3√8x^5, can be written as 3*(8x^5)^(1/2). The number 8 can be expressed as 2^3 and x^5 as (x^2)^(5/2). So, 3√(8x^5) simplifies to 3*2x^2*√(x) = 6x^2√x.

For the second expression, 4√256y^3, can be written as 4*(256y^3)^(1/2). The number 256 can be expressed as 2^8 and y^3 as (y^2)^(3/2). So, 4√(256y^3) simplifies to 4*16y = 64y.

Now, putting these values back into the original equation, we get: 6x^2√x - 64y

Final answer:

To find out how many miles a minivan will travel on 23 gallons of gas with an average of 25.8 miles per gallon, multiply the gallons by the mpg to get 593.4 miles.

Explanation:

To calculate the distance a minivan will travel on 23 gallons of gas when it averages 25.8 miles per gallon, we simply multiply the number of gallons by the miles per gallon (mpg).

The formula to use is:

Distance = Number of Gallons × Average Miles per Gallon

Using the given values:

Distance = 23 gallons × 25.8 mpg

We calculate:

Distance = 593.4 miles

Therefore, the minivan can travel 593.4 miles on 23 gallons of gas, assuming it maintains the average fuel economy of 25.8 miles per gallon.
