Answer:

132cm^2

Step-by-step explanation:

SA of square based pyramid:

SA = 2bs + b^2

b = base

s = slant height

-> 2(6)(8) + 6^2

-> 96 + 36

= 132cm^2

A scale drawing of a square has a side length of 6 millimeters. The drawing has a scale of 1 mm : 7 km. Find the actual perimete
zvonat [6]

Answer:

The real perimeter is:

P= 24 mm *\frac{7 km}{1mm}= 168 km

And the area would be:

P = 36mm^2 *\frac{(7km)^2}{(1mm)^2} = 1764 km^2

Step-by-step explanation:

For this case we know one side of a square given 6mm.

We can begin calculating the perimeter for the scale figure with this formula:

P = 4x = 4*6 mm =24 mm

The area for this case is given by:

A = x^2 = 6mm^2 = 36 mm^2

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

P= 24 mm *\frac{7 km}{1mm}= 168 km

And the area would be:

P = 36mm^2 *\frac{(7km)^2}{(1mm)^2} = 1764 km^2

Find the equation of the line that goes through the point (2, -3) and has a slope of -1.
Vladimir [108]

Answer:

y = -x - 1

Step-by-step explanation:

soo since we already know the slope we can subsitute it to the slope form equation

y = mx + b

y = -x + b

now to find the y intercept we have to subsitute the given point

-3 = -(2) + b

-3 = -2 + b

b = -1

Write a linear function F with the values F(-9)=8 and F (0) =1
Fiesta28 [93]

Given:

The values of a linear function are F(-9)=8 and F(0)=1.

To find:

The linear function.

Solution:

If a linear function passes through two points, then the equation of the linear function is:

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

The values of a linear function are F(-9)=8 and F(0)=1. It means the function passes through the points (-9,8) and (0,1). So, the equation of the linear function is:

y-8=\dfrac{1-8}{0-(-9)}(x-(-9))

y-8=\dfrac{-7}{9}(x+9)

y-8=\dfrac{-7}{9}(x)+\dfrac{-7}{9}(9)

y-8=\dfrac{-7}{9}x-7

Adding 8 on both sides, we get

y-8+8=\dfrac{-7}{9}x-7+8

y=\dfrac{-7}{9}x+1

Putting y=F(x), we get

F(x)=\dfrac{-7}{9}x+1

Therefore, the required linear function is F(x)=\dfrac{-7}{9}x+1.
