Abby earns a monthly salary of $3462 plus 2% commission. Last month, she sold
$5,250 worth of products. What was her gross pay?

Answer:

False

Step-by-step explanation:

8^3=512

12x6=3072

3072=230

The numbers dont match.

Hence, the equation is false.

Answer:

Not true

Step-by-step explanation:

= 8³ x 6

= 8 x 8 x 8 x 6

= 64 x 48

= 3072

3072 ≠ 230

=> Not true

Answer:

A) 3/4

B) 1/4

C) 1/2 / 2/4

Step-by-step explanation:

Step-by-step explanation:

she walked 5 2/3 miles in 2 2/3 hours.

so, the unit rate (speed) is 5 2/3 miles / 2 2/3 hours.

for the regular miles/hour speed we need to this back to x miles/ 1 hour.

we start by creating full fractions :

17/3 miles / 8/3 hours = 17/3 × 3/8 miles/hour =

(17×3)/(3×8) = 17/8 = 2 1/8 miles/hour

and for hours/mile we need to flip this upside-down:

8/3 / 17/3 = 8/3 × 3/17 = 8/17 hours/mile

Answer:

This is the answer.

Step-by-step explanation:

but I think you dont write the question fully.

answer: it's literally -3

Answer:

27 is ta value of x because.. first of all add allthose threee sides

3(x+2)+ 35+ 52=180(the sum of triangle)

or, 3x+6+35+52=180

or,3x=180-93

or,x=87/3

Therefore, the value of x is 29

Length = x

3 times of length = 3*x = 3x

5 metre more than 3x = 3x + 5

Breadth  = 3x + 5

Step-by-step explanation:

It's just asking you to find the slope

Plug in x=2 into given function. Then you will get f(2). Do the same to find f(5).

Then you can use slope formula to find the answer

Question 4

Explanation:

If the initial point is the origin, the coordinates of the terminal point form the vector itself in component form. We go from (-8,6) to <-8,6>. The notation change is from ordered pair to vector format.

We have a right triangle with legs of 8 and 6 units. The pythagorean theorem will help us determine the hypotenuse is 10. Therefore, the vector length is 10 units and we would say ||v|| = 10. We have a 6-8-10 right triangle.

===========================================================

Question 5

Explanation:

Vector v starts at (2,5) and ends at (-3,-2).

The x component of the vector is x2-x1 = -3-2 = -5 meaning we move 5 units to the left when going from the start point to the endpoint.

At the same time we move 7 units down because y2-y1 = -2-5 = -7 which is the y component of the vector.

The component form of vector v is

v = <-5, -7>

it says "move 5 units left, 7 units down".

Apply the pythagorean theorem to find the length of the vector.

a^2+b^2 = c^2

c = sqrt(a^2 + b^2)

||v|| = sqrt( (-5)^2 + (-7)^2 )

||v|| = 8.602 which is approximate.

Now let's use the arctangent function to find the angle

theta = arctan(b/a)

theta = arctan(-7/(-5))

theta = 54.462 which is also approximate.

There's a problem however. This angle is in Q1 but the vector <-5,-7> is in Q3. An easy fix is to add on 180 to rotate to the proper quadrant.

54.462+180 = 234.462

which is the proper approximate angle for theta.

The scale factor of the dilation can either be increased or decreased or enlarged or reduced but for the given parameters, the scale factor of the dilation is; 1.5

In dilation, the figure or image could be either enlarged or reduced. Now, we are told that OB' = 5cm and it was dilated to BB' which is 7.5 cm.

We can see that the length increased from 5 cm to 7.5cm. Thus, we can find the scale factor of dilation from;

Scale Factor = BB'/OB' = 7.5/5

Scale Factor = 1.5

The person with the highest amount of money at the end of the 8 years is Gabriella. If I were to choose one of the investment options, I would choose Gabriella's option.

The formula that can be used to determine the future value of the investment with compounding is:

FV = P (1 + r)^nm

Where:

Future value with continuous compounding =  : A x e^r x N

Where:

Future value with monthly compounding = $2000 x ( 1 + 0.035/12)^(12 x 8) = $2645.18

Future value with continuous compounding: 1000 x e^0.018 x 8 = $8,145.30

Total = $8,145.30 + $2645.18 = $10,790.48

Future value with quarterly compounding = 2500 x (1 + 0.012 / 4)^(4 x 8) = $2,751.50

Future value with quarterly compounding = 500 (1 .0225)^(8x4) = $1019.05

Total = $3,770.55

$3000 x e^0.032 x 8 = $24,780.42

Future value with exponential increase = 1050 x (1.015)^8 = $1,182.82

Future value with biannual compounding = 1950 x (1 + 0.028/2)^(8 x 2) = $2435.80

Total = $3618.62

Answer:

[tex]\{-9,-1,5,7\}[/tex]

Step-by-step explanation:

The range would be the corresponding y-values for the given set:

[tex]h(-5)=2(-5)+1=-10+1=-9\\\\h(-1)=2(-1)+1=-2+1=-1\\\\h(2)=2(2)+1=4+1=5\\\\h(3)=2(3)+1=6+1=7[/tex]

Thus, the range of [tex]h[/tex] using set notation is [tex]\{-9,-1,5,7\}[/tex]. Also, see attached graph.

Answer:

See answers below

Step-by-step explanation:

Problem 1

Recall that [tex]tan(A+B)=\frac{tanA+tanB}{1-tanAtanB}[/tex] and that [tex]tan(\frac{\pi}{4})=1[/tex]. Using these two facts, we can rewrite the expression:

[tex]\frac{1+tanx}{-1+tanx}\\\\-\frac{1+tanx}{1-tanx}\\ \\-\frac{tan(\frac{\pi}{4})+tanx}{1-tan(\frac{\pi}{4})tan(x)}\\ \\-tan(x+\frac{\pi}{4})\\ \\tan(\frac{3\pi}{4}-x)[/tex]

Hence, the first choice is correct

Problem 2

[tex]cos(\frac{x}{2})=\sqrt{3}-cos(\frac{x}{2})\:;\: 0\leq x < 360^\circ\\\\2cos(\frac{x}{2})=\sqrt{3}\\ \\cos(\frac{x}{2})=\frac{\sqrt{3}}{2}\\\\\frac{x}{2}=\frac{\pi}{6}+2\pi n,\frac{11\pi}{6}+2\pi n\\ \\ x=\frac{\pi}{3}+4\pi n,\frac{11\pi}{3}+4\pi n\\ \\ x=60^\circ+720n^\circ, 660^\circ+720n^\circ\\\\x=60^\circ[/tex]

It's helpful to use the unit circle to solve these kinds of problems. Therefore, the third answer is correct.

Problem 3

Because [tex]sin\theta=-\frac{5}{13}[/tex] and our parameters are [tex]\pi < \theta < \frac{3\pi}{2}[/tex], the triangle must be in Quadrant III where [tex]sin\theta < 0[/tex] and [tex]cos\theta < 0[/tex].

You may recall the double angle formula [tex]sin2\theta=2sin\theta cos\theta[/tex]. We can find [tex]cos\theta[/tex] using [tex]sin\theta[/tex] with the Pythagorean Identity [tex]sin^2\theta+cos^2\theta=1[/tex] keeping our parameters in mind:

[tex]sin^2\theta+cos^2\theta=1\\\\(-\frac{5}{13})^2+cos^2\theta=1\\ \\\frac{25}{169}+cos^2\theta=1\\ \\cos^2\theta=\frac{144}{169}\\ \\cos\theta=-\frac{12}{13}[/tex]

Thus, [tex]sin2\theta=2sin\theta cos\theta=2(-\frac{5}{13})(-\frac{12}{13})=2(\frac{60}{169})=\frac{120}{169}[/tex], which means the third option is correct.

Answer:

2 times a number, plus 1, plus 2 times a number, is equal to 4x + 2.

The way they factored ↓

2 x 2 = 4

4x = 4 times a number or itself multiple times

4 + 2 is the same as a number times 1 equals 2.

If that's the case, x = 2.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Jane spends $5.75 for lunch during 5 school days.

Hence, We get;

The amount spend money for lunch during 10 school days is,

⇒ $5.75 × 10 / 5
