Answer:

F(4) = 97

Step-by-step explanation:

F(x)= x³+2x²+1

when x = 4

F(4)= 4³+2(4²)+1

= 4³+2(4²)+1

= 64 + 2(16) + 1

= 64 + 32 + 1

= 97

Alborosie

Answer: (3-1)×(7+5)

Step-by-step explanation:

There are mainly several ways to get 24

- 2×12

- 3×8

- 4×6

- add all of them together

- complicated ones can include large numbers minus another large number

Use try-check-revise, to find the way that fits 24

For this question, we used 2×12, which results in (3-1)×(7+5)

Hope this helps!! :)

For the formula F = 95K – 455.67, what is the value of K when F = 0?
Inessa [10]

Answer:

<em>K = 4.8</em>

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

F = 95K - 455.67

We are required to find the value of K when F=0:

95K - 455.67 = 0

Adding 455.67:

95K = 455.67

Dividing by 95;

K = 4.8

How do you rename a mixed number as a fraction khan academy.
elena-s [515]

Answer:

There's no answer choices but I can give you an example.  

Step-by-step explanation:

  1. Let's say you have \frac{25}{4}.  
  2. Think about what the closest whole number 25/4 will give you.  Since 24 and 25 are close you can do 24/4 and get 6.  
  3. Now since you took one number away from the 25 you have a remainder.  
  4. Since the denominator is 4 your final answer would be 6\frac{1}{4}.  

Hopefully this helps.

HELP PLEASE. Check picture. I have tried but cannot seem to get it.
Sauron [17]

Answer:

884^{-7}

Step-by-step explanation:

Start by simplifying the denominator of the fraction. When multiplying exponents of the same base, you can add the exponents. This is also known as the product rule.

a^x\cdot a^y=a^{x+y}

["a" is the base, and "x" and "y" are the exponents]

Using this we find...

884^{58}\cdot884^{46}=884^{58+46}=884^{104}

When dividing exponents of the same base, you can subtract the exponents. This is also knows as the quotient rule.

a^x\div a^y=a^{x-y}

Using this we find...

\frac{884^{97}}{884^{104}}=884^{97-104}=884^{-7}
