Answer:
The final value of the stock is $3,996.66
Step-by-step explanation:
Percentage Change
The x% of a number N is calculated as x*N/100. If there is an increase, that number is added to the original value, then the new value is:
N'=N+x*N/100
Operating:
N'=N(1+x/100)
That formula makes it easier to find the new values of increasing quantities. When the percentage is for decreasing, then the formula becomes:
N'=N(1-x/100)
The original value of the stock is N1=3,789. The first change is an increase of 6%, then the new value is:
N2=3,789(1+6/100)=3,789*1.06=$4,016.34
The stock value now decreases by 7%:
N3=4,016.34(1-7/100)=4,016.34*0.93=$3,735.20
Finally, the value increases again by 7%:
N4=3,735.20(1+7/100)=3,735.20*1.07=$3,996.66
The final value of the stock is $3,996.66
find the zero for f (x)=80-10x
Answer: =80/11
Step-by-step explanation:x=80-10x
We move all terms to the left:
x-(80-10x)=0
We add all the numbers together, and all the variables
x-(-10x+80)=0
We get rid of parentheses
x+10x-80=0
We add all the numbers together, and all the variables
11x-80=0
We move all terms containing x to the left, all other terms to the right
11x=80
x=80/11
x=7+3/11
How can you solve a system of two equations or inequalities in which one is linear and one is quadratic?
Answer:
Solve the inequality as though it were an equation. The real solutions to the equation become boundary points for the solution to the inequality. Make the boundary points solid circles if the original inequality includes equality; otherwise, make the boundary points open circles.

G.CO.5: Quadrilateral PQRS is shown on the coordinate plane.
Part A:
Quadrilateral PQRS is transformed by
translating it right 6 units and then
rotating it 90° clockwise about the
origin. Graph the image of
quadrilateral PQRS after these two
transformations.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Translation right 6 units adds 6 to every x-coordinate. Rotation 90° CW is the transformation (x, y) ⇒ (y, -x). The sequence of transformations gives ...
(x, y) ⇒ (y, -x-6)
Then the coordinates of the transformed figure are ...

Q(4, 12) ⇒ Q'(12, -10)
R(4, -2) ⇒ R'(-2, -10)

A sports-equipment researcher was interested in the relationship between the speed of a golf club (in feet per second) and the distance a golf ball travels (in yards). Information was collected on several golfers and was used to obtain the regression equation y = 2x - 106, where x represents the club speed and y is the predicted distance. What is the predicted distance of a ball that is hit with a club speed of 168 ft/seconds?

III. Solve the problems below: 42 boys and 63 girls took part in an art competition.(4 pts) Find the ratio of the number of boys to the number of girls (always in the simplest form). Find the ratio of the number of boys to the number of girls to the total number of children (always in the simplest form).
Answer:
Ratio of number of boys to girls= 2:3
Ratio of number of boys to girls to total number of children= 2:3:5
Step-by-step explanation:
42 boys and 63 girls took part in an art competition
The ratio of the number of boys to the number of girls can be calculated as follows
= 42/63
= 2:3
The ratio of the number of boys to girls to total number of children can be calculated as follows
= 42/63/105
= 2:3:5
Over which interval is the graph of y = cos(x) strictly increasing?

StartFraction pi Over 2 EndFraction less-than x less-than StartFraction 3 pi Over 2 EndFraction
π < x < 2π
Answer:
D
Step-by-step explanation:
The interval at which the graph of y = cos x is strictly increasing is
π < x < 2π.
Option D is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
y = cos x
Cos π = cos (π/2 + π/2) = Sin π/2 = 1
Cos 2π = Cos (π + π) = - Cos π = - Cos (π/2 + π/2) = - Sin π/2 = -1
We see that,
y = Cos x is strictly increasing from -1 to 1.
Thus,
y = cos x is strictly increasing from π < x < 2π.

Solve for r 5(r-10)=-51
Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
Answer:
r = - ¹/₅ or -0.2Step-by-step explanation:
5(r - 10) = -51
5r - 50 = -51
5r = -51 + 50
5r = -1
r = - ¹/₅ or 0.2

Insert two geometric means between 729 and 64
Answer:
324 and 144
Step-by-step explanation:
We require
a₁, a₂, a₃, a₄
where a₂ and a₃ are the required geometric means
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 729 and a₄ = 64, thus
729(r³) = 64 ( divide both sides by 729 )
r³ = [tex]\frac{64}{729}[/tex] ( take the cube root of both sides )
r = [tex]\sqrt[3]{\frac{64}{729} }[/tex] = [tex]\frac{4}{9}[/tex] , then
a₂ = 729 × [tex]\frac{4}{9}[/tex] = 81 × 4 = 324
a₃ = 324 × [tex]\frac{4}{9}[/tex] = 36 × 4 = 144
Thus
729, 324, 144, 64

CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠FNT and Determine m∠KTU.
Answer:
Angle FNT = 120 Degrees because the angles labeled 7a+50 and 14a-20 are the same because the lines are parralel so you can set them equal to eachother 7a+50=14a-20 and find that a=10 After this you plug 10 into either 7a+50 and 14a-20 to get 120. You know Angle FNT is 120 degrees because it is directly across from 7a+50 which means they are the same. Then the measure of Angle KTU is 60 because Angle KTN + Angle KTU needs to add up to 180.

Answer:
Formula of triangle: A = 1/2 x b x h
Step-by-step explanation:
Solve the base of the triangle by solving the distance between points (-2,0) and (f, -5) in units, and then do the same for height: find distance between points (-2, 6) and (-2, 0). Once you find the distance, input value of base and height into the formula and solve to get the area!
