Answer:

45 square inches

Step-by-step explanation:

Given :

Area of base of a triangular pyramid = 9 inches

Length of height of triangular pyramid = 10 inches

We know that :

[tex]\tt \: \color{hotpink}volume\: of \: a \: triangular \: pyramid \color{plum}= \frac{1}{3} Bh[/tex]

Which means :

Volume of this triangular pyramid :

[tex] = \tt \frac{1}{3} \times 9 \times 10[/tex]

[tex] =\tt \frac{9 \times 10}{3} [/tex]

[tex] =\tt \frac{90}{3} [/tex]

[tex]\color{plum} =\tt 30 \: {inches}^{3} [/tex]

Thus, the volume of this pyramid = 30 inches³

Answer:

Since they're asking you to find the missing sides "y" and "x" here's what you need to do....

Step-by-step explanation:

1) This is the 45-45-90 Triangle.

2) y = 20 becasue this is an isocelese triangle - meaning a triangle that has 2 sides of equal lengths!

3) in order to find x (which is the hyptoneus) you have to do

       [tex]\sqrt{2}[/tex] * leg (use on of the legs)

    =  [tex]20\sqrt{2}[/tex]

also I think 45 degrees is there just to throw you off. And I'm pretty positive this is the correct answer, and i'm 100% sure that y = 20 is correct!

Actually Welcome to the Concept of the Average rate of change.

The average rate of change can be calculated by, finding the change of the two readings and getting a average between them.

here, for x =3 to x =5

1.) in the interval, x =3 to x = 4

the change is ==> 287 - 125 = 162

2.) in the interval, x = 4 to x=5

the change is ==> 549-287 = 262

Now the average ==> 162+262/2 ===> 212

Hence the average rate of change is 212

Answer:

1.54

Step-by-step explanation:

the z-score is calculated with the formula z= ( raw score - mean) / standard deviation

z= (236 - 193) / 28

z= 43 / 28

z= 1.5357

Answer:

6x+18

Step-by-step explanation:

Perimeter is the sum of all the sides:

(x+4)+(x+4)+(x)+(x+1)+(4)+(2x+5)

x+x+x+x+2x+4+4+1+4+5

6x+18

Step-by-step explanation:

plug in -3x for y

-9x-5(-3x)= -48

-9x+15x= -48. its +15 because negative times negative is.

positive

6x= -48 (-9 +15=6) now divide both sides by 6

x= -8

now you can solve for y by plugging in -8 for x

-3(-8) =y

24= y

Answer:

A. 5 1/2 and D. 11/2

Step-by-step explanation:

Make improper fraction

8*1+3=11/8

Solve by multiplying:

4*11/8

44/8

Simplified is 11/2

We can turn it back into a mixed number

2*5+1=11 so 5 1/2

Answer:

The zeros are 0, 4, 6.

The y-intercept is 0.

Step-by-step explanation:

f(x) = x^3 - 10x^2 + 24x

x^3 - 10x^2 + 24x = 0

x(x^2 - 10x + 24) = 0

x(x - 4)(x - 6) = 0

x = 0 or x - 4 = 0 or x - 6 = 0

x = 0 or x = 4 or x = 6

y-intercept:

Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.

You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).

Let x = 0.

f(0) = 0^3 - 10(0^2) + 24(0)

f(0) = 0

y-intercept: 0

Step-by-step explanation:

Answer:

y = 3x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3, then

y = 3x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = 3x - 7 ← equation of line
