Determine the value of k if g(x)=4x+k is a tangent to f(x)=-x²+8x+20
Answer:
k=24
Step-by-step explanation:
The tangent of the function f at x=a, can be found by differentiating f w.r.t. x and then replacing x with a.
f=-x^2+8x+20
Differentiating both sides:
f'=(-x^2+8x+20)'
By sum rule:
f'=(-x^2)'+(8x)'+(20)'
By constant multiple rule:
f'=-(x^2)'+8(x)'+(20)'
By constant rule:
f'=-(x^2)+8(x)'+0
By power rule:
f'=-2x+8
f' at x=a is -2a+8
This is the slope of any tangent line to the curve f.
The slope of g is 4 if you compare it to slope intercept form y=mx+b.
So we gave -2a+8=4.
Subtracr 8 on both sides: -2a=-4
Divide both sides by -2: a=2
The tangent line to the curve at x=2 is y=4x+k.
To tind y we must first know the y-coordinate of the point of tangency.
If x=2, then
f(2)=-(2)^2+8(2)+20=-4+16+20=12+20=32
So the point is (2,32).
g(x)=4x+k and we know g(2)=32.
This gives us:
32=4(2)+k
32=8+k
k=32-8
k=24
From the tangent given, the value of k will be 24.
How to solve the tangentFrom the information given, g(x) = 4x + k and this is a tangent to f(x)= -x² +8x + 20.
f(x)= -x² +8x + 20
= f'(x) = -2x + 8
The slope of tangent = -2x + 8 at (x , y)
g(x) = 4x + k
Hence, slope = 4
-2x + 8 = 4
Collect like terms
-2x = 4 - 8
-2x = - 4
Divide both side by -2
-2x/-2 = -4/-2
x = 2
f(x)= -x² +8x +20
where, x = 2
y = -2² + 8(2) + 20
y = 32
Hence (2 , 32) lies on g(x)= 4x+k
32 = 4(2) + k
32 = 8 + k
k = 32 - 8
k = 24
In conclusion, the value of k is 24.

Sebastian grew 21-3 inches each year for the past 3 years. How many inches total has Sebastian grown in the past 3 years?
Answer:
the Answer is 21.3 x 3
Step-by-step explanation:
inches that grew each year for the past 3 years - 21.3
SO here 1 year = 21.3 inches

21,/ or,/ 19Please help me, I will give the best answer brainliest. I have a deadline finish of today, and I really want to get my work done... The following figures show the first two steps of a proof of the pythagorean theorem, which of the following statements about this proof is false? Thank you if you can help :)
Answer:
so since there isn't any pics to work with, here we go.
the pytha theorem states that a^2 + b^2 = c^2, you've probably seen/heard this all the time but really know what it means.
It means the the shorter side of the triangle (the ones that aren't the hypotenuse) multiplied by themselves, and then added together equals the hypotenuse also multiplied by itself.
So if i have a triangle with sides lengths of 3 and 4, and I want to calculate the hypotenuse length, the equation would be 3^2 + 4^2 = x^2
we then get 9 + 16 = x^2 –––––> 25 = x^2 ––––> √25 = x
so the hypotenuse equals 5.
hope this helps.
Use the graph to write a linear function that relates y to x
can someone help please, thank you :)
Answer:
y = 1/3x + 3
Step-by-step explanation:
Points on the graph: (0, 3) and (3, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-3)/(3-0)
m= 1/3
Point-slope intercept:
y - y1 = m(x - x1)
y - 3 = 1/3(x - 0)
y - 3 = 1/3x
y = 1/3x + 3

How many more hours will it take the Miller family to reach their destination? Use paper to show your work. Enter your answer in the box.
Answer:
1 7/10 hours
Step-by-step explanation:
They need to drive a total of 8 hours. After they drive 3 2/3 hours, they have 4 1/3 left. Then, after another 2 3/5 hours, they now have 1 7/10 hours left.
The number of hours will it take the Miller family to reach their destination is 1¹¹/₁₅ hours.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the Miller family must drive 8 hours to reach their destination. They drive 3²/₃ hours before stopping for the first time. Then they drive 2³/₅ hours before stopping again.
The time will be calculated as,
Time = 8 - 3²/₃ - 2³/₅
Time = 8 - 11/ 3 - 13 / 5
Time = 26 / 15

Marlon had 6 hits in 15 at bats. How does Marlon's
hits to at bats ratio compare to Adrian's?
Adrian had 4 hits in 10 bats.
Answer:
Hence, both Marlon and Adrian both have the same at bats percentage.
Step-by-step explanation:
Marlon's at bats :
Number of at bats = 15
Hits = 6
Hit percentage = 6/15 * 100% = 40%
Adrian :
Number of at bats = 10
Hits = 4
Hit percentage = 4/10 * 100% = 40%
Hence, both Marlon and Adrian both have the same at bats percentage.

Amanter on the edge of a mol has the shape a rectangular prism. It is 9 inches high, 2 inches wide, and 14 feet long. How much water can the gutter hold in cubic inches in gallons? Use the fact that
1231 inches
The gather canto cubic inches of water
Answer:
1.1 gallons
Step-by-step explanation:
Given that the shape of the gutter is in the form of a rectangular prism with length 14 feet, width 2 inches and of height 9 inches.
The volume of the gutter = length x width x height
= 14 x 2 x 9
= 252
The volume of the gutter = 252 cubic inches
But with the given fact, we divide the volume determined by 231 inches.
Then,
the required volume in gallons = [tex]\frac{252}{231}[/tex]
= 1.090908
The gutter can hold water of 1.1 gallons.
