What is the surface area of the square pyramid represented by the net? Enter your answer in the box. m² An unfolded square base

OlgaM077 [116]

Answer:

The surface area of the square pyramid is $144\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to

$SA=B+Ph/2$

where

B is the area of the base

P is the perimeter of the base

h is the height of the pyramid

$B=6^{2}=36\ m^{2}$

<u>Find the perimeter of the base P</u>

$P=4*6=24\ m$

The height is $h=9\ m$

substitute the values

$SA=36+24*9/2=144\ m^{2}$

Find the nth term of the AP -2 -5 -8....

timofeeve [1]

Answer:

an = -2 -3(n-1)

Step-by-step explanation:

an = a1+(n-1) d

a1 =-2

d = -5--2

d = -5+2

d=-3

we are decreasing by 3 each time

an = -2 + (n-1) * -3

an = -2 -3(n-1)

The first step for deriving the quadratic formula from the quadratic equation, 0 = ax2 bx c, is shown.step 1: –c = ax2 bxwhich b

Ksju [112]

Answer:

option (b) is correct.

First step to solve for deriving the quadratic formula from the quadratic equation is completing the square.

Step-by-step explanation:

Given : the quadratic equation $ax^2+bx+c=0$

We have to find the first step for deriving the quadratic formula from the quadratic equation.

Quadratic formula is given by $\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Consider the given quadratic equation $ax^2+bx+c=0$

Divide the equation by a, we get,

$x^2+\frac{b}{a}x+\frac{c}{a}=0$

Take $\frac{c}{a}$ to other side, we get,

$x^2+\frac{b}{a}x=-\frac{c}{a}$

Add $(\frac{b}{2a})^2$ to both side, we get,

$x^2+\frac{b}{a}x+(\frac{b}{2a})^2=(\frac{b}{2a})^2-\frac{c}{a}$

Thus, the left side is in the form of $(a+b)^2=a^2+b^2+2ab$

On solving, we get,

$(x+\frac{b}{2a})^2=(\frac{b}{2a})^2-\frac{c}{a}$

Then solve for x , we get quadratic formula $\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Thus, first step to solve for deriving the quadratic formula from the quadratic equation is completing the square.

Thus, option (b) is correct.

Nadya [2.5K]

Answer:

Step-by-step explanation:

From the information given:

$\mathbf{H_o: \mu = 9.7 \ hours}$

$\mathbf{H_1: \mu > 9.7 \ hours}$

The type 1 error is rejecting $\mathbf{H_o}$ when

The meaning of Type 1 error is rejecting the claim that the mean running time is 9.7 hours when actually the mean running time is greater than 9. 7 hour.
