Find h(-1) if h(x) =- 3|3x – 6|– 3?

Answers

Answer:

Step-by-step explanation:

h(-1) = - 3|3(-1) - 6| - 3

h(-1) = - 3|-3 - 6| - 3

h(-1) = - 3|-9| - 3

h(-1) = - 3(9) - 3

h(-1) = - 27 - 3

a What is the correct quotient?
bWhat mistake did CJ likely make?
a. He multiplied the reciprocals of both fractions.
b. He added -3/4 and 1/4
c. He multiplied-3/4 by 1/4
d. He multiplied using the reciprocal of -3/4.

Answers

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

From the question,

We are to determine the correct quotient.

The given division operation to be carried out is -3/4 divided by 1/4

The correct quotient can be determined as shown below

[tex]-\frac{3}{4} \div \frac{1}{4}[/tex]

Multiply [tex]-\frac{3}{4}[/tex] by the reciprocal of [tex]\frac{1}{4}[/tex]

The reciprocal of [tex]\frac{1}{4}[/tex] is [tex]\frac{4}{1}[/tex]

Then, we get

[tex]-\frac{3}{4} \times \frac{4}{1}[/tex]

This gives

[tex]-\frac{12}{4}[/tex]

= -3

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4.

Hence, the correct quotient is -3

The mistake CJ likely made is He multiplied using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

rectangular equation for the curve whose parametric equations are x = 2cosθ, y = cos2θ.

Answers

The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].

In this question, we have a set of parametric equation which must be reduced into a single rectangular equation both by algebraic and trigonometric means, that is to say:

[tex]x = f(\theta), y = g(\theta) \to y = h(x)[/tex]

If we know that [tex]x = 2\cdot \cos \theta[/tex] and [tex]y = \cos 2\theta[/tex], then the rectangular equation is:

[tex]y = \cos 2\theta[/tex]

[tex]y = \cos^{2}\theta - \sin^{2}\theta[/tex]

[tex]y = 2\cdot \cos^{2}\theta -1[/tex]

[tex]\cos \theta = \frac{x}{2}[/tex]

[tex]y = 2\cdot \left(\frac{x}{2} \right)^{2}-1[/tex]

[tex]y = \frac{x^{2}}{2} -1[/tex]

The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].

PLEASE HELP!!!!! A satellite telescope has a parabolic dish. Satellite signals are collected at the focal point (focus) of the
parabola. The distance from the vertex of the parabolic dish to the focus is 40 feet. The vertex of the dish is
located at a point 50 feet above the ground and 100 feet to the east of a computer that reads and records
data from the telescope. The diameter of the dish is 160 feet.

Answers

The dish illustrates operations on a parabola.

The depth of the parabolish dish is 160 feet.

The bowl is said to be a parabola.

So, we have:

[tex]\mathbf{(x -h)^2 = 4p(y - k)}[/tex]

Where:

[tex]\mathbf{Focus: p = 40}[/tex]

[tex]\mathbf{Vertex:(h,k) = (0,0)}[/tex]

From the question, the diameter is 160 feet.

So, the radius (r) is:

[tex]\mathbf{r = \frac{160}{2} = 80}[/tex]

So, the coordinate of the depth of the parabola would be:

[tex]\mathbf{(x,y) = (60 + 100,y)}[/tex]

[tex]\mathbf{(x,y) = (160,y)}[/tex]

Substitute these values in [tex]\mathbf{(x -h)^2 = 4p(y - k)}[/tex]

So, we have:

[tex]\mathbf{(160 - 0)^2 = 4 \times 40 \times (y -0)}[/tex]

[tex]\mathbf{160^2 = 160y}[/tex]

Divide both sides by 160

[tex]\mathbf{160 = y}[/tex]

Rewrite as:

[tex]\mathbf{y = 160 }[/tex]

Hence, the depth of the parabolish dish is 160 feet.

Which will have a higher effective interest rate - a payday loan for $1500 that

O A. A payday loan for $1500 that is due in 12 days with a fee of $90,

о
C. A payday loan for $1500 that is due in 10 days with a fee of $90,
since it has the longer period
D. A payday loan for $1500 that is due in 10 days with a fee of $90,
since it has the shorter period

Answers

The higher effective interest rate is for A payday loan for $1500 that is due in 10 days with a fee of $90, since it has the shorter period, the correct option is B.

What is Interest Rate?

An Interest Rate is the rate at which a person either takes a loan, or a person lends money to somebody.

The interest rate is different for different types of loans, some interests are simply calculated on the principal, called as Simple Interest while some are calculated on both the principal and the interest, called as Compound Interest.

A payday loan has principal of $1500

It is due in 12 days, so time period is 12 days.

The interest amount is $90

I = P * R *T / 100

90 = 1500 *12 *R /100

R = 0.5 %

A payday loan has principal of $1500

It is due in 10 days, so time period is 10 days.

The interest amount is $90

90 = 1500 *10 *R /100

R = 0.6 %

The rate of interest is more for a payday loan for $1500 that is due in

10 days with a fee of $90.

Hence, the correct answer is A payday loan for $1500 that is due in 10 days with a fee of $90, since it has the shorter period, the correct option is B.

Find the measure of the angle with the red dot (NOT X.)
Picture Included. Thank you!

Answers

Step-by-step explanation:

I can't see picture very well but as I see first angle is

-4x+5 and second is -13x+39 ( if it isn't, correct me)

sum of this angles is 180° because they are inner angles

(-4x+5) + (-13x+39) = 180

-4x+5 -13x+39=180

-17x+44=180

-17x = 180-44

-17x= 136

x= -8

angle -4x+5 will be:

-4*-8 + 5= 32+5= 37°
