Plzzz Help ASAP! This image shows a square pyramid what is the surface area of this square pyramid?
padilas [110]

Answer:

72\ ft^{2}

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces

so

SA=b^{2}+4[\frac{1}{2}bh]

where

b is the length side of the square base

h is the height of the triangular face

Remember that

Each lateral triangular face is a triangle 45°-90°-45°

so

h=b/2

we have

b=6\ ft

so

h=6/2=3\ ft

substitute in the formula

SA=6^{2}+4[\frac{1}{2}(6)(3)]=72\ ft^{2}

What is the input value other than 7 for which g(x)=4
Vsevolod [243]

<u>Given:</u>

It is given that the value of the graph when the input 7 is g(x)=4

We need to determine the value of x when g(x)=4

<u>Value of x when </u>g(x)=4<u>:</u>

The value of x can be determined by using the graph.

From the graph, we need to determine the value of x when g(x)=4 other than the value x = 7.

This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.

Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.

Therefore, the input value is x = -8 which makes g(x)=4

Hence, the input value other than 7 for which g(x)=4 is x = -8.

X km/h = y mph
3241004551 [841]
Let's first write down the equations which we will require to solve for this problem.

Equation No. 1 -
x km/h = y mph

Equation No. 2 -
8 km/h = 5 mph

First of all, we will make y the subject by calculating the km/h when mph = 1. We will accomplish this by dividing both sides by 5 as displayed below:

Equation No. 2 -
8 km/h = 5 mph
5 mph = 8 km/h
5 / 5 mph = 8 / 5 km/h
1 mph = 8 / 5 km/h

Through this, we have found out:

m = 8 / 5

We will use the y = mx formula in order to obtain our final equation. We will substitute the value given in the second equation into the formula.

y = mx
y = ( 8 / 5 ) x
