If f(x) = 4x2 and g(x) = x+1, find (*•g)(x).
Answers
Answer:
(f · g)(x) = 4x³ + 4x²
Step-by-step explanation:
(f · g)(x) = f(x) · g(x)
We have f(x) = 4x² and g(x) = x + 1. Substitute:
(f · g)(x) = (4x²)(x + 1) use the distributive property
(f · g)(x) = (4x²)(x) + (4x²)(1)
(f · g)(x) = 4x³ + 4x²

The greatest common factor of 35 and 63 is,
⇒ 7
We have to given that;
Find the greatest common factor of 35 and 63.
Now, We can find LCM of number,
⇒ 35 = 7 × 5
⇒ 63 = 7 × 3 × 3
We know that;
The highest number that divides exactly into two more numbers, is called Greatest common factors.
Therefore, the greatest common factor of 35 and 63 is,
⇒ 7

The required, Mrs. Simpson's speed was 42 miles per hour.
What is speed?
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
To find the speed (or velocity) in miles per hour, we need to divide the distance traveled (in miles) by the time taken (in hours).
Mrs. Simpson drove 105 miles in 2 1/2 hours, which can be written as:
Time taken = 2.5 hours
Distance traveled = 105 miles
Speed = Distance / Time
Speed = 105 miles / 2.5 hours
To divide 105 by 2.5, we can convert the mixed number 2 1/2 to an improper fraction:
2 1/2 = 5/2
Then we can divide:
Speed = 105 miles / (5/2) hours
Speed = 105 miles * (2/5) hours
Speed = 42 miles/hour
Therefore, Mrs. Simpson's speed was 42 miles per hour.

you have to know the meaning of the line
the line goes from -1 to 3 so t is more than -1 and less than 3 so -1>t>3,
but there are special points
the point where the line stops at -1 is shaded in meaning that values above -1 and including -1 are in the solution -1<t
the other point at 3, is not shaded in, meaning that points below 3 and not including 3 are included so t<3
the solution is -1<t<3 or 3>t>-1 or C
