Answer:

100 ft^2

Step-by-step explanation:

The large upper rectangle has dimensions 12 ft by 23 ft, and thus has area 276 ft^2. The small lower rectangle is 15 ft by (12 - 7) ft, or 15 t by 5 ft, and thus has area 75 ft^2. The total area is

75 ft^2 + 25 ft^2, or 100 ft^2.

PLEASE ANSWER FAST What is the average of the following two numbers? 5.67 x 10^-21 and 7.24 x 10^-19

adell [148]

Answer: The average of two numbers is $3.64835\times 10^{-19}$ .

Explanation:

The first term is,

$5.67\times10^{-21}$

The second term is,

$7.24\times10^{-19}$

Average formula is,

$Average=\frac{\text{Sum of observations}}{\text{Number of observations}}$

$Average=\frac{5.67\times10^{-21}+7.24\times10^{-19}}{2}$

$Average=\frac{5.67\times 10^{-2}\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{0.0567\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{(0.0567+7.24)\times10^{-19}}{2}$

$Average=\frac{(7.2967)\times10^{-19}}{2}$

$Average=3.64835\times10^{-19}$

Therefore, the average of two numbers is $3.64835\times 10^{-19}$ .

Type the correct answer in each box. Use numerals instead of words.

Natali5045456 [20]

Given:

Consider the given function is $f(x)=-(x+1)(x-3)(x+2)$ .

To find:

The remaining zero and y-coordinate of y-intercept.

Solution:

We have,

$f(x)=-(x+1)(x-3)(x+2)$

For zeros, $f(x)=0$ .

$-(x+1)(x-3)(x+2)=0$

$(x+1)(x-3)(x+2)=0$

$(x+1)=0,(x-3)=0,(x+2)=0$

$x=-1,x=3,x=-2$

So, three zeros of given function are -1, 3 and -2.

Putting x=0 in the given function, we get

$f(0)=-(0+1)(0-3)(0+2)$

$f(0)=-(1)(-3)(2)$

$f(0)=-(-6)$

$f(0)=6$

So, the y-coordinate of y-intercept of the given function is 6. It means the y-intercept is at point (0,6).

Therefore, the zeros of the function $f(x)=-(x+1)(x-3)(x+2)$ are –1, 3, and -2 and the y-intercept of the function is located at (0,6).
