Find the x-intercept and y-intercept of the line???

Answer:

step by step answer at least

The value of one fourth squared times one fourth raised to the zero power end quantity all raised to the second power is 1/256.

The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

From the information, the exponent illustrated will be:

= (1/4^2 × 1/4^0)²

= (1/16 × 1)²

= (1/16)²

= 1/16 × 1/16

= 1/256

The value is 1 / 256.

Answer:

  28.072°, 61.928°

Step-by-step explanation:

You want the measures of the acute angles in a right triangle with sides 8, 15, 17.

Any of the (inverse) trig functions can be used to find the angles. You know the acute angles are complementary, so finding one tells you the measure of the other.

  Tan = Opposite/Adjacent

The smallest angle (A) is adjacent to side 15 and opposite side 8.

  tan(A) = 8/15

  A = arctan(8/15) ≈ 28.072°

The complement is angle B:

  B = 90° -28.072° = 61.928°

__

Additional comment

We have taken sides {a, b, c} = {8, 15, 17}. The angles opposite those sides are A, B, C.

You can also use ...

  A = arcsin(8/17)

  B = arccos(8/17)

When the capital letter Y is rotated 180°,  Our point A(x,y) rotates 180 degrees counterclockwise around the origin to become A' (-x,-y). transforming both x and y negative is all we do as a result.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given,

The capital letter Y is rotated 180°.

The coordinates shift from (x, y) to (x, z) when you reflect a figure across the x-axis (x, -y). The coordinates would change from (x, -y) to (x, y) if you then reflected it over the y-axis (-x, -y). As a result, reflecting over the x- and y-axes will be similar to turning 180 degrees counterclockwise. Our point A(x,y) rotates 180 degrees counterclockwise around the origin to become A' (-x,-y). transforming both x and y negative is all we do as a result.

Step-by-step explanation: Please give brianlist

Answer:

The first step is to label the points being (1,2.3),(6,6.8) in which the first ordered pairs is the number of weeks, and the second one is the dollars in millions.

Hence, the slope is: m=(6.8-2.3)/(6-1) = 4.5/5 = 9/10 = 0.9

The slope represents the dollar rate in the millions per week. In this case, the movie grossed $0.9 million per week from week one to the sixth week.

You will have $1,09,545.455 in the account in 20 years. An you will put total $72,000 in the account. And you will earn $37,545.455 of total interest.

Here,

We deposit $300 each month earning 4% interest compounded monthly.

we will find the future value of this amount after 20 years.

for finding future value, The general formula is

FV=PV∙(((1+i)ⁿ-1))/i

Where,

FV= future value

PV=present value

i=interest

n=time period

now, our PV=300$ and we have 4% interest compounded monthly

i.e.

i=4/100∙1/12

i=0.0033

And, the period of time is

n=20×12

n=240

Now, we will calculate the future value

FV=300 (((1+0.0033)²⁴⁰-1))/0.0033

FV=300 (((1.0033)²⁴⁰-1))/0.0033

FV=300 (((2.205)-1))/0.0033

FV=300(365.15)

FV=1,09,545.455$

Now, The total money you put into account is

total amount=300×20×12

total amount=72,000$

The time taken for the rocket to reach its maximum height is; 1.25 seconds.

The maximum height reached by the toy rocket is; 44.5 feet.

It follows from the task content that the maximum height reached by the rocket is to be determined.

The given function is; h (t) = -16 t² + 40t + 7.

Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.

Therefore; at maximum height;

h'(t) = 0

h'(t) = -32t + 40 = 0

-32t = -40

t = -40/-32

t = 1.25 seconds.

Therefore, the time taken for the rocket to reach its maximum height is; 1.25 seconds.

Also, the maximum height reached by the rocket is at; h (1.25);

h(1.25) = -16(1.25)² + 40 (1.25) + 7

The shares of $2.25 are 200 and the shares of $2.75 are 700.

According to the question,

We have the following information:

An investor bought 700 shares of stock, some at $2.25 per share and some at $2.75 per share. And the total cost was $1825.00.

Now, let's take the shares of $2.25 to be x and the shares of $2.75 to be y.

So, we have the following expression:

x+y = 700

x = 700-y ....(1)

2.25x+2.75y = 1825 ...(2)

Putting the value of x from equation 1:

2.25(700-y)+2.75y = 1825

1575-2.25y+2.75y = 1825

1575+0.5y = 1825

0.5y = 250

y = 250/0.5

y = 500

Now, putting the value of y in equation 1:

x = 700-y

x = 700-500

x = 200

Hence, the shares of $2.25 are 200 and the shares of $2.75 are 700.

Considering the given sample, it is found that:

a) The confidence interval is: (71.43, 77.17).

b) The interval does not contain 78, hence the manufacturer's claim is not correct.

c) The sample size needed is: 55.

The t-distribution is used when the standard deviation for the population is not known, and the bounds of the confidence interval are given according to the following rule:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which the variables of the equation are presented as follows:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 12 - 1 = 11 df, is t = 2.201.

Using a calculator, the other parameters for the interval are given as follows:

[tex]\overline{x} = 74.3, s = 4.52, n = 12[/tex]

Hence the lower bound of the interval is:

74.3 - 2.201 x 4.52/sqrt(12) = 71.43.

The upper bound is:

74.3 + 2.201 x 4.52/sqrt(12) = 77.17.

For item c, we have that:

The margin of error is:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

Then the sample size is obtained when M = 1.04 as follows:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]1.04 = 1.96\frac{3.91}{\sqrt{n}}[/tex]

[tex]1.04\sqrt{n} = 1.96 \times 3.91[/tex]

[tex]\sqrt{n} = \frac{1.96 \times 3.91}{1.04}[/tex]

What are parallel lines?

No matter how far they may extend in either direction, parallel lines are ones that are equally spaced apart from one another and never cross.

If line m is parallel to line n, the two angles given will be congruent because they will be alternate exterior angles (which are congruent).

Here, we have

m = 132°
