Find the area of the rectangle

Answer:

20 units

Step-by-step explanation:

calculating volume of a rectangular prism is done by multiplying length x width x height. the prism is 5 units tall, 2 units wide, and 2 units long (or deep), so you multiply 5x2x2 to get twenty

Answer:

rate of change is 4.

Step-by-step explanation:

rate of change is the slope, so, pick any two relations given to us in the table.

(-3, -14) and (-1, -6).

slope = y2 - y1/ x2 - x1

slope = -6 - (-14)/-1-(-3)

slope = 8/2 = 4.

the rate of change is 4.

because it does

Answer:

y < 12

Step-by-step explanation:

Add 5 on both sides since the opposite of subtraction is addition. Then cross it out where you will be left with y and 7 + 5 equals 12 so the answer is: y < 12

Answer:

Step-by-step explanation:

use the law of Cosines so that you can solve a SSS triangle

Cos(C) = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex]  / 2ab

c is the side of 24 for our triangle and angle C is the top one in the picture.

C = arcCos ( [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex]  / 2ab )

C = arcCos ( -32 / 480 )

C = 93.82255373 °

the angles at the top are each half of that or 46.91127 °

let's solve another angle for the big triangle now let's go for the one on the left and call it A

Cos(A) = [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex]  / 2bc   where a = 20

A = arcCos( [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex]  / 2bc)

A = arcCos( [tex]24^{2}[/tex] + [tex]12^{2}[/tex] - [tex]20^{2}[/tex] / 2*12*24

A = arcCos(320 / 576)

A = 56.2510 °

then angle B is  180 =93.823 + 56.251 + B

29.926 ° = B

so now we know all 3 angles.. seems like a lot of work , huh  :D

for the triangle with the question mark we now know two angles and the Hyp, so let's use Law of Sines to find that last side  :)

Sin(A)/a = Sin(B) /b  where A can be the angle at the top and B can be the angle at the base. which we have to find still  :/  

it's 180 = 46.9112 + 29.926 + B

103.162 = B

Sin(46.91127 ) / a = Sin(103.162) /20

Sin(46.91127 ) * 20 / Sin(103.162) = a

14.99998 = a    I feel confident this is supposed to be 15 and I have a tiny bit of rounding error..

? = 15   there you go  

your answer is 15

Answer:

Options A, D and E

Step-by-step explanation:

If a number in square root can't be solved Or square root of the number can't be removed then it is a surd.

Option A

√17 = Surd [Can't be simplified further]

Option B

√36 = 6

Not a surd

Option C

√100 = 10

Not a surd

Option D

√15 = Surd

Option E

√30 = Surd  

Therefore, Options A, D and E are the surd.

Answer:

Step-by-step explanation:

The graphed function has:

The answer options:

f(x) = (x + 5)^3(x + 1)^2(x - 2)^2

f(x) = (x + 5)^2(x + 1)(x - 2)^3

f(x) = (x + 5)^3(x + 1)^2(x - 2)^2(x - 5)

f(x) = (x + 5)(x + 1)^3(x - 2)^2

Answer:

C

Step-by-step explanation:

Answer: x=20 y=20√2

Since this is a 45-90-45 right triangle, so sides are going to be the same. To solve for y, you have to use Pythagorean theorem. (a^2+b^2=c^2) So put in the a and b values, in this case, it's 20 and 20. (20^2+20^2=c^2) Then you can solve the exponents, (400+400=c^2) add them up (800=c^2), then square root everything which gives you y=20√2 or 28.28(rounded)

Answer:

9.4km

Step-by-step explanation:

6.2^2 +7.1^2 = x^2

so 38.44+ 50.41= 88.85

x^2= 88.85 so x = 9.4

Sorry if it's really confusing lol, if you need help i could explain it further but your answer is 9.4

I don't know the answer please

Answer:

36 square inches.

Step-by-step explanation:

Since the original figure was a square, all four side lengths are equivalent. The area for the square will be:

[tex]A=s^2[/tex]

Where s is the length of one side.

One side is increased by nine inches and the other side was decreased by two inches. The area of the resulting rectangle is 60 square inches.

So, one of the new sides is (s + 9).

And the other is (s - 2).

The area with these dimensions is 60. Thus:

[tex]60=(s-2)(s+9)[/tex]

Solve for s. Distribute:

[tex]60=s^2+7s-18[/tex]

Isolate the variables:

[tex]s^2+7s-78=0[/tex]

Factor:

[tex](s+13)(s-6)=0[/tex]

Zero Product Property:

[tex]s+13=0\text{ or } s-6=0[/tex]

Solve for each case:

[tex]s=-13\text{ or } s=6[/tex]

A side length cannot be negative. So, our only solution is:

[tex]s=6\text{ inches}[/tex]

Since each side of the square measures six inches, the area of the original square will be 36 square inches.

Answer:

Step-by-step explanation:

Solve for x, 3x < -17 - 4 so 3x < -21 so x < -7

Since the x you are looking for is less than -7, draw an open circle on -7 (don't color it in, leave it like a donut) then darken the number line to the left of -7 and draw an arrow at the end

Please answer my question

Answer:

a = 15, b = - 14

Step-by-step explanation:

Given the 2 equations

[tex]\frac{a}{5}[/tex] - [tex]\frac{b}{2}[/tex] = 10 ( multiply through by 10 to clear the fractions )

2a - 5b = 100 → (1)

a - b = 29 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the a- term

- 2a + 2b = - 58 → (3)

Add (1) and (3) term by term to eliminate a

0 - 3b = 42

- 3b = 42 ( divide both sides by - 3 )

b = - 14

Substitute b = - 14 into (2) and evaluate for a

a - (- 14) = 29

a + 14 = 29 ( subtract 14 from both sides )

a = 15
