Answer:
-69 (Answer b)
Step-by-step explanation:
Apply the power rule for differentiation:
(d/dx){-4x^2 + 11x} = -8x + 11
Now substute 10 for x:
f '(x) = -8(10) + 11 = -80 + 11 = -69 (Answer b)
Answer:
b
Step-by-step explanation:
Using the power rule to differentiate each term
Given
f(x) = - 4x² + 11x , then
f'(x) = - 8x + 11
At x = 10
f'(10) = - 8(10) + 11 = - 80 + 11 = - 69 → b

Find the area of the figure. Round to the nearest tenth.
HELP ASAP!!
Answer:
A
Step-by-step explanation:
f=1/2(a+b)×h1/2(1.6+4)×22.8×25.6 since to round off 5.6 to the nearest tenth consider the hundredths' value of 5.6 which is 0. therefore the tenths value of 5.6 remains 5.615+26+56+19+17+19+9+19

Sally buys 9 tins of cat food
For how many days will the cat food feed her 2 cats?
Answer:
18 days
Step-by-step explanation:
Given, Amount of cat food eaten by each cat per day = 1/4 th of a tin
Amount of cat food eaten by 2 cats per day = 1/4 × 2 part of a tin = 1/2 of a tin No. of days 9 tins will last = 9 × 2 = 18

Write an equation of the circle with center (-2, 6) and radius 7.
Answer:
( x + 2 )² + ( y - 6 )² = 49
Step-by-step explanation:
→ Write the form of an equation of a circle
( x - a )² + ( y - b )² = r²
→ Substitute in the centre remembering to switch the signs
( x + 2 )² + ( y - 6 )² = r²
→ Substitute in radius
( x + 2 )² + ( y - 6 )² = 49

10) What changes when a figure is
transformed by a reflection, rotation,
or a translation?
A) its area
C) its position
B) its size
D) its perimeter
Answer:
size because when a figure is squeezed, it shrinks and changes the size
Answer:
Its Position
Step-by-step explanation:
Reflection-when the shape is reflected over an axis
Rotation-when the shape is rotated around a singular point
Translation-when the shape is moved up/down or left/right
None of these change any part of the shape it just moves the shape around. :)
please help i don’t understand
Answer:
18.38Explanation:
since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!

After 5 years, Marcel's account earned $900 in interest. If the interest rate (in decimal form) is 0.06, how much did Marcel initially invest?
Answer:
$3000
Step-by-step explanation:
I= PRT÷100
where,
I = interest = 900
T= 5
R/100 = 0.06
P = ?
I= PRT/100
900= P × 5 × 0.06
P = 900÷ 0.3
P= 3000

The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
What is a regression model?A regression model is used to determine the association and correlation between two variables
Using a graphing calculator, the sine regression model of the dataset is:
[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]
To calculate y(30), we substitute 30 for x in the equation.
So, we have:
[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]
Evaluate the product
[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]
Evaluate the difference
[tex]y =20.077 \sin(13.041) + 67.577[/tex]
Evaluate the sine value
[tex]y =20.077 *0.4570+ 67.577[/tex]
Evaluate the product
[tex]y =9.1752+ 67.577[/tex]
Evaluate the sum
[tex]y =76.7522[/tex]
Approximate
[tex]y \approx 76.8[/tex]
Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

The dot plot shows the favorite sport to play according to some middle school students chosen at random. Which statement is true according to the information in the dot plot ?
What are the options?
Answer:
B: More than 25% of the students chose football and tennis as their favorite sport to play.
Step-by-step explanation: You need to find the total, which is 50. Since it says more than 25 percent of the students chose football and tennis your answer will need to be more then 25 percent. You add football plus tennis (10+3=13). Now you set up your proportion- 50 as your whole/total, 13 as your part, and substitute you percent with a variable like (p), then 100. Cross multiply. I did a shortcut which replaces the Ice Ice Baby process, so multiply 13x100= 1300, then your product divide it by 50 ( total) 1300/50= 26. This makes the statement true.
