Step-by-step explanation:
1) Find the first derivative of f(x). 2) Plug x value of the indicated point into f '(x) to find the slope at x. 3) Plug x value into f(x) to find the y coordinate of the tangent point. 4) Combine the slope from step 2 and point from step 3 using the point-slope formula to find the equation for the tangent line.
If 140 students want to go on the Coronado Island field trip and are ALL riding together, how many cars will they need if each car holds 6 people?
Answer:
24
Step-by-step explanation
bruh...
1. Divide 140 by 6 and you get 23.3 repeating
2. When you multiply 23 times 6 you get 138. (not enough seats)
3. So, you would need to have at least 24 cars in order for everyone to go on the trip. (24 x 6 = 144 seats)

Find the value of x.
A. 22.5
B.40
C.45
D.95
Answer:
x = 22.5
Step-by-step explanation:
The tangent- secant angle x is half the difference of the measures of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (4x + 5 - 50 ) = x ( multiply both sides by 2 )
4x - 45 = 2x ( subtract 2x from both sides )
2x - 45 = 0 ( add 45 to both sides )
2x = 45 ( divide both sides by 2 )
x = 22.5
One more than the quotient of a number x and four
Answer:
x/4+1
Step-by-step explanation:
Because it says one more than the quotient, we are dealing with addition and division. 1 more means plus 1. The quotient of a number x and 4 means the answer to the division problem of x and 4. This means x/4. Then add all parts of the problem to get x/4 +1

Predict what will happen to the coordinates of a point (x,y) as the point rotates counterclockwise (CCW) about the origin to produce point (x’,y’). Choose rotation angles of 90 degrees, 180 degrees, and 360 degrees. Express your answer in terms of x and y. Be sure to watch your signs.
Answer:
Step-by-step explanation:
If a point (x, y) is rotated counterclockwise by the angles given in the table attached,
Rule for the rotation at an angle of 90° CCW about the origin,
(x, y) → (-y, x)
Rule for the rotation at an angle of 180° CCW about the origin,
(x, y) → (-x, -y)
Rule for the rotation at an angle of 270° CCW about the origin,
(x, y) → (y, -x)
Rule for the rotation at an angle of 360° CCW about the origin,
(x, y) → (x, y)
Angle of rotation x' y'
90° -y x
180° -x -y
270° y -x
360° x y
Answer:
Angle of Rotation (CCW) x′ y′

Jim ran 15 miles in 5 days. At this rate, how many days will it take Jim to run 165 miles?
Answer:
55 days
Step-by-step explanation:
Given
Jim ran 15 miles in 5 days
no. of miles ran in 5 days = 15 miles
dividing LHS and RHS by 5
no. of miles ran in 5/5(=1) days = 15/5 miles = 3 miles
no. of miles ran in 1 day = 3 miles
let the no. of days taken to run 165 miles be x ----A
No of miles ran in x days = x*no. of miles ran in 1 day = 3x miles
thus, From A
3x = 165
x = 165/3 = 55
Thus, it took 55 days for JIM to run 165 miles

Prove theorems about triangles
a) It is possible and it is the only proper value of angle 2
b) Explanation Below
Angle 1 adds to the two other internal angles to get 180
(angle1) + 30 + 42 = 180
angle1 + 72 = 180
angle1 = 180-72
angle1 = 108 degrees
Subtract this from 180 to find the measure of angle 2
angle2 = 180 - angle1
angle2 = 180-108
angle2 = 72
A shortcut is to use the remote interior angle theorem to add up the interior angles 30 and 42 to get 72 as our exterior angle that is not adjacent to any of the interior angles we just added. Hence the "remote" portion.
if 9x = 18 what is the value of x
Answer:
The correct answer is x = 2.
Step-by-step explanation:
To solve this problem, we should first remember that in solving equations, our goal is to get the variable (in this case, x) by itself on one side of the equation. To do this, we must divide both sides of the equation by 9 to get rid of the coefficient on the x term. This is modeled below:
9x = 18
9x/9 = 18/9
x = 2
Therefore, the correct answer is x = 2.
To check your answer, you can always plug the value for x back into the equation. For example, 9(2) = 18 is a true statement, so we know that we got the correct answer.
Hope this helps!
The value of x from the equation 9x = 18 is x= 2.
To find the value of x in the equation 9x = 18, we need to isolate x on one side of the equation.
To do that, we can divide both sides of the equation by 9:
(9x) / 9 = 18 / 9
Simplifying:
x = 2
Therefore, the value of x is 2.
We can also say that,
By dividing both sides of the equation by 9, we determined that when x is multiplied by 9, it equals 18, so x must be 2 in order for the equation to be true.

Use trigonometry to resolve the following vectors into components. Describe the vectors using vector
notation
Answer:
v ≈ (3.28512, 20.74146)
Step-by-step explanation:
v = 21(cos(81°), sin(81°))
v ≈ (3.28512, 20.74146) . . . . (x, y) components
The notation varies among authors. The vector can be written as ...
(r, θ) = (21, 81°)
r∠θ = 21∠81°
r cis θ = 21 cis 81°
v = 21·e^(i·9π/20)
(x, y) ≈ (3.28512, 20.74146)
v = 3.28512i +20.74146j . . . . perhaps this is the vector notation you want (i and j are unit vectors in the x- and y-directions, respectively)
change 45/8 to mixed fraction
Answer: 5 and 5/8
Step-by-step explanation: To write an improper fraction as
a mixed number, we divide the denominator into the numerator.
So in this problem, we divide 8 into 45.
8 divides into 45 five times with a remainder of 5.
Also, the denominator of the improper fraction
will become the denominator of the mixed number.
So we have 5 and 5/8
The fraction 45/8 is equal to the mixed fraction 5 5/8.
How to write it as a mixed fraction?To convert the fraction 45/8 into a mixed fraction, follow these steps:
Step 1: Divide the numerator (45) by the denominator (8) to determine the whole number part of the mixed fraction.
45 ÷ 8 = 5 with a remainder of 5
Step 2: The quotient obtained in Step 1, 5, represents the whole number part of the mixed fraction. The remainder, 5, becomes the new numerator.
Step 3: Write the mixed fraction using the whole number, numerator, and denominator.
The mixed fraction is 5 5/8.

what’s the answer ?
Answer:
EF = 34
Step-by-step explanation:
EF + FG = EG , substitute values
17x + 3x + 7 = 18x + 11, that is
20x + 7 = 18x + 11 ( subtract 18x from both sides )
2x + 7 = 11 ( subtract 7 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Thus
EF = 17x = 17(2) = 34
Answer:
34
Step-by-step explanation:
g First, you need to find the value of x. To do this you need to add the lengths of EF and FG and set it equal to the total length of EG, then solve.
EF=17x, FG= 3x+7, EG = 18x+11
17x+3x+7=18x+11
Combine like terms.
20x+7=18x+11
-7 -18x
Isolate x.
2x = 4
Divide both sides by 2.
x=2
Now that we have the value for x, we need to plug it into the length of EF to find the numerical value.
17x = 17(2) = 34
I have a question about my math homework : transform y=k(x) by translating it down 3 units. Lable the new function p(x) . What happens to the y-coordinate in each new ordered pair?
Answer:
We have the function y = k(x).
We want to define a new function p(x), such that is equal to k(x) but translated down 3 units.
When we have a general case of a function y = f(x), the function g(x) = f(x) + A is a translation of A units up (if A is positive) or A units down (if A is negative).
Then if we want to go 3 units up, we should have:
p(x) = k(x) + 3.
So now our points are:
(x, y) = (x, p(x)) = (x, k(x) + 3)
So for all the points the y-coordinate has ben mooved 3 units up.

What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
During a vacation together, Bob spent twice as much as Josh, who spent four times as much as Ralph.
Let x be the amount of money spent by Ralph.
Then Bob spent 8x and Josh spent 4x.
If Bob and Ralph together spent $180. Then the equation will be
8x + x = 180
9x = 180
x = 180 / 9
x = $20
Then the money spent by Bob and Josh will be
Bob = 8x = 8 × 20 = $160
Josh = 4x = 4 × 20 = $80
Then the amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.
