1. Find p(-3) if p(x) = 4x3 - 5x2 + 7x - 10
SVETLANKA909090 [29]

Answer:

1) -184

2) 13(m^{4}) ^{2}-3(m^{4})+4

Step-by-step explanation:

For problem number 1, Let's start by substituting all the x's for -3

So the equation will look like

p(-3)=4(-3)^{3}-5(-3)^{2}+7(-3)-10

Now, lets simplify by solving the exponents

First we'll do -3^{3} which equals -27

Now we'll do -3^{2} which equals 9

So now our equation looks like

p(-3)=4(-27)-5(9)+7(-3)-10

Now, we are going to multiply all these numbers

First 4(-27) which equals -108

Now -5(9) which equals -45

And finally 7(-3) which equals -21

Now our equation looks like

p(-3)= -108-45-21-10

Now we can solve

-108-45-21-10=-184

Given the following expressions:
Tamiku [17]

Step-by-step explanation:

Step 1:

A .    5 with an exponent of 3 times 5 with an exponent of -4

= 5^{3} * 5^{-4}  = 5^{3-4}= 5^{-1} = 1/5

B .   (1/4) with an exponent of 3 times (1/4) with an exponent of 2

= (1/4)^{3}  * (1/4)^{2} = (1/4)^{3+2} = (1/4)^{5} = 1/1024  

C. Same as above

D.  \\\frac{(-7)^{5} }{(-7)^{7} }  =  (-7)^{5-7}  =  (-7)^{-2}  =1/7^{2} = 1/49

Step 2 :

All the above expressions have a value between 1 and 2

Translate each sentence into a formula
Bas_tet [7]
1) Perimeter=2length+2width
This is the formula for finding the perimeter of a rectangle

2) Density=mass/volume
The “Quotient” is the answer to a division problem (like how the “sum” is the answer to an addition problem) which is why we know to divide mass and volume

3) Force = mass*acceleration
The “product” is the answer to a multiplication problem which is why we know to multiply mass and acceleration

4) surface area = 6*L^2
The formula used to calculate the area of a square is L^2. The problem tells us that surface area is the sum of all the faces of a 3D shape. Because there are 6 sides on a cube, we multiply L^2 by 6.

Hope this helps!
