100 POINTS FOR BRAINLIEST! according to the image, whats the answer? Answer wisely for the full 100

stepan [7]

Answer:

Step-by-step explanation:

1. To find the area of a semicircle the formula is

$A=\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2$

The square

$A=a^2=2^2=4m^2\\6.283+4=10.283m^2$

2. Triangle

$A=\frac{ab}{2} \\=\frac{6*2.5}{2} \\=7.5m^2\\7.5*2=15m^2$

Rectangle

$A=wl=8*13=104m^2$

$104-15=89m^2$

Semicircle

$A=\frac{\pi r^2}{2} \\=\frac{\pi 3^2}{2} \\\\=14.137m^2$

Square

$A=a^2=6^2=36$

$36-14.137=21.863m^2$

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's $\frac{x_1}{y}\;and\;\frac{x_2}{y}$ are two fractions in same terms.

Thus, $\frac{x_1}{y}\div\frac{x_2}{y}$ {Divided by a fraction is equal to multiplied by its reciprocal}

= $\frac{x_1}{y}\times\frac{y}{x_2}$

Quotient is simply the quotient of their numerators.

Example could be:

$\frac{2}{7}\div\frac{3}{7}$

$\frac{2}{7}\times\frac{7}3}$

$\frac{2}{3}$

2 is first numerator and 3 is the second numerator.

How do you do this question?

vivado [14]

Answer:

-1

Step-by-step explanation:

dy/dt = y² − 1 = (y + 1) (y − 1)

At t = 0, y = 0, and dy/dt = -1. Therefore, y is initially decreasing.

As y decreases, dy/dt increases. When y = -1, dy/dt = 0 and changes signs from negative to positive.

As y increases above -1, dy/dt again becomes negative. So y continues to approach -1 as t approaches infinity.

If f(x) = x^2 -5x +1 and g(x) =5x+4 what is the value of g•f (-2)

Arlecino [84]

Answer:

The value of $gof (-2)=79$

Step-by-step explanation:

We have

$f(x) = x^2 -5x +1 \\\\f(-2) = (-2)^2 -5\times-2 +1 \\\\=15$

Now we need to find

$gof (-2)=g(15)$

$g(15) =5\times15+4\\\\=79$

The perimeter of a square is represented by the expression 4(4.3 - 6). Which statement is true?O The perimeter can also be repre

lana66690 [7]

the perimeter is:

4(4x - 6)

Applying distributive property:

4(4x) - 4(6)

16x - 24

Then, the perimeter can also be represented by 16x - 24 because 4(4x - 6) can be simplified to 16x - 24
