What is the inverse of f(x)=x^4 + 7 for x>0 where function g is the inverse of function f
The first answer
cbjsabcakvscds
The inverse function of the function f(x) will be [tex]\rm g(x) = \sqrt[4]{x - 7}, x \geq 7[/tex]. Then the correct option is A.
What is the inverse function?Let the function f is given as
y = m(x + a) + c
Then the inverse function of the function f will be given by the swapping of x with y and y with x.
The function is given below.
f(x) = x⁴ + 7
The inverse function of f(x) will be
x = [g(x)]⁴ + 7
[g(x)]⁴ = x - 7
[tex]\rm g(x) = \sqrt[4]{x - 7}[/tex]
The function is valid for x ≥ 7.
The inverse function of the function f(x) will be [tex]\rm g(x) = \sqrt[4]{x - 7}, x \geq 7[/tex]. Then the correct option is A.

A statistics teacher was interested in the relationship between the number of days students waited to start a project and the score that project received (out of 100 points). Information was collected on several students and was used to obtain the regression equation y = –3.64x + 96.5, where x represents the number of procrastination days and y is the predicted grade. What is the predicted grade of a student who procrastinated for 2 days?
25.96
85.58

1. Jenny is organising a barbecue. There are 30 bread rolls in a pack. There are 16 sausages in a pack. She needs exactly the same number of bread rolls as sausages. What is the smallest number of each pack she must buy?
Answer:
2. Tom, Sam and Matt are doing a show by counting drum beats .They decided to donate the collecting money for the poor children for their studies. Tom hits a snare drum every 2 beats. Sam hits a kettle drum every 5 beats. Matt hits a bass drum every 8 beats. Tom, Sam and Matt start by hitting their drums at the same time. How many beats is it before Tom, Sam and Matt next hit their drums at the same time? What value you can see in their act
Answer:
If you answer I promise I will make you the brainiest, like and I will vote 5
Answer:
Step-by-step explanation:
First find the LCM of 30, 16. This will give the common number of sausages and bread rolls
30 = 2 * 3 * 5
16 = 2 * 2 * 2 * 2
LCM = 2* 2 * 2 * 2 * 3 * 5 = 240
240 sausages and 240 bread rolls
Number of Sausage pack = 240 ÷ number of sausages in a pack
= 240 ÷ 16
= 15
Number of bread roll pack = 240 ÷ number of bread rolls in a pack
= 240 ÷ 30
= 8
Jenny should buy 8 pack of bread rolls and 15 pack of sausage
2) LCM of 2 , 5 , 8 = 40
Tom, Sam, Matt will hit their drum same at 40 minutes
Number of beats hit by Tom before reaching 40 minutes = 40/2 =20 hits
Number of beats hit by Sam before reaching 40 minutes = 40/5 = 8 hits
Number of beats hit by Matt before reaching 40 minutes = 40/8 = 5 hits

Answer:
107
Step-by-step explanation:
it looks like a right angle
Answer:
The answer is 107 degrees.
Step-by-step explanation:
The sum of all the angle of a triangle must equal 180 degrees. That being said if you grab 180 and subract 44 and 29 from it you get 107 degrees. 107+44+29=180. If this did not equal 180 the answer would be wrong but since it does it is right.
b is a point between a and c where ac = 5x, ab = 12, and bc = 3x + 2. what is the measure of the length of ac?
Answer:
AC=22
Step-by-step explanation:
The measure of the Length of AC is; 35
We are given;
ac = 5x
ab = 12
bc = 3x + 2
We are told that b is between a and c. This means that;ab + bc = ac
Thus;
12 + 3x + 2 = 5x
14 + 3x = 5x
Subtract 3x from both sides to get;
5x - 3x = 14
2x = 14
x = 14/2
x = 7
Thus, ac = 5x = 5 * 7ac = 35

Answer:
30*
Step-by-step explanation:
If ABD is 105* then it would be <ABC+<CBD=105*. We know that <ABC is 75* so we can fill that in. 75*+<CBD=105*. Then we solve.
75* + <CBD = 105*
-75* -75*
<CBD=30*

Mr. Peter's has 80 sheets of colored paper seven of his students need it for a project. how many sheets are left over?
Answer:
Three sheets will be left over.
Step-by-step explanation:
Well, if you have 80 sheets of paper, and seven students need it, you would first divide the 80 sheets to the seven students using the equation 80 ÷ 7 = 11.4. You won't be giving fractions of paper to the students so you would round to 11. If each of the seven students gets 11 sheets of paper, 77 sheets will have been used. 80 - 77 = 3. So, there will be three sheets left over.

Help with G and H plz
Answer: For G the answer is x=30, for H x is 30
Step-by-step explanation:
G. The square means 90 degrees and the equation would be 90+3x=180. Subtract 90 from both sides would give you 3x=90 and divide it by 3 would give you x=30
H. The two lines means that both sides are congruent and so 75x2=150 150+x=180 subtract 150 from both sides would give you x=30
⭐️ I NEED HELP ASAP: Sam and Joe are brothers. Joe is five less than three times the age of Sam. If the product of their ages is 28, how old are Joe and Sam?
Please explain how you solved it too! Thank you!
Answer:
joe=6
Sam=11
Step-by-step explanation:
lets see...
i explain 1by1
firstly we know that joe is 5 - 3 x Sam
(read the sentences VERY CAREFULLY)
then, we put Sam as math variable "s"
it will be; 5-3 x S
[tex]5 - 3 \times s[/tex]
the total of their age is 28
[tex]5 - 3 \times s = 28[/tex]
simplify it
it will be 5-S3=28
then you will get 11 right
that will be sam's age
-5 and it will be Joe's age
Subtract. Then, in two or more complete sentences, explained how you found the difference. In your explanation, make sure to include any equivalent expressions you wrote, any rules you used, and the answer.
