determine the value of k if g(x) =4x+k is a tangent to f(x)= -x² +8x +20
Answer:
22
Step-by-step explanation:
222
The value of k in the given functions is; 24
What is the value of the function to the tangent?
We are given the functions;
g(x) = 4x + k as a tangent to f(x) = -x² +8x +20
For f(x) = -x² +8x +20
=> f'(x) = -2x + 8
Thus, slope of tangent at ( x , y) = -2x + 8
For g(x) = 4x + k
g'(x) = 4.
Thus, slope is 4
Therefore;
-2x + 8 = 4
-2x = -4
x = 2
Putting 2 for x in f(x) gives;
f(2) = -2² + 8(2) + 20
f(2) = 32
Thus, it is at (2 , 32)
Thus, (2 , 32) lies on g(x) = 4x + k
4(2) + k = 32
k = 32 - 8
k = 24

Find tan A for the triangle below.
Answer:
Hola Amigo mate!
The answer is
Tan A= 0.667Here's the step by step explanation:-So, here tan A means opposite side divided by the adjacent side.
TAN A= [tex]\frac{Opposite}{adjacent}[/tex]
Opposite of side A is 10cm and its adjacent side is 15cm!
So, TAN A IS:- [tex]\frac{10}{15}[/tex]
Tan A= 0.667

Answer:
a) y=|(1\2)x-2| + 4
b)y=|(1/2)x-2|+2
c)y=|(1/2)x-1|+3
d)y=|(1/2)x-3|+3
Step-by-step explanation:
Translating up and down is done outside of the absolute value and is intuitive in that up is added to the original value and down is negative. Left and right is shown within the absolute value and is the opposite of what you would think it to be in that left is added and right is subtracted.

Answer: x=4
Step-by-step explanation:
Since this is a rectangle we already know that all the angles are 90, so we can do this:
46+10x+4=90
50+10x=90
10x=40
x=4
A professional tennis player has a serve-return rate of p = 0.71. A random sample of 55 serve returns is selected. Which of the following is the mean of the sampling distribution of p hat ?
Mu Subscript p hat Baseline = p = 0.71
Mu Subscript p hat Baseline = n p = 55 (0.71) = 39.05
Mu Subscript p hat Baseline = 1 minus p = 1 minus 0.71 = 0.29
Mu Subscript p hat Baseline = n (1 minus p) = 55 (1 minus 0.71) = 15.95
Answer:
I would say A is the answer

A bicycle store costs $2800 per month to operate. The store pays an average of $50 per bike. The average selling price of each bicycle is $90. How many bicycles
must the store sell each month to break even?
The store must sell bicycles each month to break even.
(Type a whole number.)
Answer:
70 Bikes
Step-by-step explanation:
[using b as a variable for bikes]
2800=-50b+90b
[2800 is total cost of store with-50 being cost per bike and 90 being selling point of bike]
2800=40b [simplified by combining -50 with 90]
70=b [divided 2800 by 40 to get the break even for the store]

Step-by-step explanation:
What is the solution to the system of linear equations graphed here?
A (2,-1)
B (-1,2)
C (2,1)
D) No Solution
Answer:
One solution, A) (2 , -1)
Step-by-step explanation:
The solution is where the two lines intersect. If the lines do not intersect, it is no solution. If the line intersects once (like in the picture), it has one solution. If it intersects more than once (x), then it will have x amount of solutions.
In this case, the intersection is at (2 , -1), therefore, A) (2 , -1) is your answer.

Mrs. Abner randomly chooses one boy and one girl to participate in a spelling bee. The probability that Alex is chosen from the boys is 0.08.
The probability that Jane is chosen from the girls is 0.14.
Which is closest to the probability that Alex and Jane are chosen for the spelling bee?
Answer:
The probability of Alex and Jane getting picked is 0.0112 or 1.12
Step-by-step explanation:
Ok, so the probability that Alex is picked is 0.08, then in order for jane to be picked it is another 0.14.
That means that we must figure out what 14% of 0.08 is 0.0112
0.0112 = 1.12%

Mrs. Hales then tells Kyle to write an equation showing that the volume, V, of each of his prisms is equal to l × w × h
Kindly check the complete version of the question on the picture attached below :
Answer:
B.) 4 * 3 * 3
Step-by-step explanation:
Unit volume of cube = 48 unit³
Using the volume relation :
Volume = Length * width * height
V = l * w * h
To obtain the odd representation, we calculate the volume of the dimensions given in the option and select the option which does not yield a volume of 48 unit³
A.) 8 * 2 * 3 = 48 unit³
B.) 4 * 3 * 3 = 36 unit³
C.) 6 * 2 * 4 = 48 unit³
D.) 3 * 2 * 8 = 48 unit³
Hence, prism with dimension 4 * 3 * 3 cannot be one of Kyle's prism

Tommy's salary increases by 4% each year. This year, Tommy's salaray was $42,250. How much will her salary be in 7 years?
**Simplify ALL of the way and round to the NEAREST whole number**
Answer:
$295,750
Step-by-step explanation:
Given
Tommy's salary increases by 4% each year.
Increase to 4%
1 year = $42,250
7 years = $?
To find
So if 1 year is $42,250, then to find 7 years, you multiply the given by what you are trying to find.
Set up.
1/42250 x 7/x =
295,750
Therefore, Tommy's salary be in $295,750 7 years.
