Question 5 of 10
If f(x) = 4x2 + 1 and g(x) = x2 – 5, find (f+ g)(x).
O A. 3x2 + 6
B. 5x2 - 6
C. 3x2 - 4
D. 5x2 - 4
Answers
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) = (4x² + 1) + (x² - 5) = 5x² - 4. (D)
Answer:
D. 5x^2-4
Step-by-step explanation:
We are asked to find (f+g)(x), which is really just the sum of the two functions.
(f+g)(x)=f(x)+g(x)
We know the the functions are:
• f(x)= 4x^2+1
• g(x)=x^2-5
Substitute the functions in.
(f+g)(x)=(4x^2+1)+(x^2-5)
Add the functions by combining like terms. For this equation, the like terms are those with x^2 and the constants.
(f+g)(x)= (4x^2+x^2)+(1-5)
Add the terms with x^2
(f+g)(x)=(5x^2)+(1-5)
Add the constants or terms without variables.
(f+g)(x)=(5x^2)+(-4) = 5x^2-4
The sum of the functions is D. 5x^2-4

exactly twice as many shirts as jeans, how many pairs of jeans can Jess buy without exceeding $500?
Answers
Answer:
167 pairs
Step-by-step explanation:
Represent jeans with J and shirts with S
[tex]S = 2J[/tex]
[tex]Amount = \$500[/tex] --- Maximum
Required
Determine the number of pair of jeans he can buy
To represent as an inequality, we have:
[tex]S + J \leq Amount[/tex]
[tex]S + J \leq 500[/tex]
Substitute 2J for S
[tex]2J + J \leq 500[/tex]
[tex]3J \leq 500[/tex]
Divide through by 3
[tex]J \leq 500/3[/tex]
[tex]J \leq 167[/tex]

Why are whole numbers rational numbers? Use 15 as an example.
Answers
Answer:
Every whole number n can be written as a fraction of integers.
Step-by-step explanation:
Every whole number n can be written as a fraction of integers: x=x/1.
If we use 15 as an example, it would be 15 = 15/1. 15/1 is 15.
So whole numbers are rational
Whole numbers are rational numbers because all whole numbers can be expressed in the form a/b. Hence, 15 can be expressed as a rational fraction thus 15/1
When a number can be expressed in the form a/b ; such that the value of the denominator, b ≠ 0 ; then the number is said to be rational. Whole numbers are positive integer values and as such, they are not decimals. Every whole number can be expressed such that the denominator is 1 ; hence, they can be expressed in the form a/b.15 as a whole number can be rewritten as 15/1. Hence, all whole numbers are rational.

volcano Puu Puai in Hawaii was formed in 1959 when a massive “lava fountain” erupted. The lava shot from the ground with an initial velocity of 350 feet per second.
a. For how long was the lava in the air until it returned to the ground?
b. What was the maximum height of the lava?
c. After how many seconds did the maximum height occur?
Answers
Answer:
a)Tt = 21,41 s
b) y(max) = 1873 ft
c) t = 10,70 s
Step-by-step explanation:
We assume that this is a case of vertical shooting then:
a) Vf = V₀ - g*t
Vf = 0 -g*t = -V₀
t = V₀ /g t = 350 ft/s / 32,7 ft/s²
t = 10,70 s time for lava to reach y maximum
a) Then Tt = 2*10,7 Tt = 21,41 s
Lava was in the air for Tt = 21,41 s
b) y = y₀ + v₀*t - (1/2 )*g*t²
for y = ymax we get:
y(max) = 0 + 350*10,70 - 0,5* 32,7* ( 10,70)²
y(max) = 3745 - 1872
y(max) = 1873 ft
c) t = 10,70 s

[tex]The \: slope \: is \: \frac{7}{3} .[/tex]
Step-by-step explanation:
To find the slope, we have to turn the equation into the slope-intercept form which is:
[tex]y = mx + b[/tex]
The slope is the m in that form.
we will solve for y.
[tex]7x - 3y = 21 \\ \frac{- 7x \: \: \: \: \: \: = - 7x}{ - 3y = - 7x + 21} \\ \\ \frac{ - 3y}{ - 3} = \frac{ - 7x + 21}{ - 3} \\ y = \frac{7}{3} x - 7[/tex]
Answer:
Step-by-step explanation:
-3y = -7x + 21
3y = 7x - 21
