ANSWER: y = 1

STEPS:

first, find the slope by using the formula

which is also represented as m

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

where from point (-8, 1) x1 is -8 and y1 is 1

then from point (7, 1) x2 is 7 and y2 is 1

so we substitute into the formula

[tex] \frac{1 - 1}{7 - ( - 8)} = \frac{0}{7 + 8} = \frac{0}{15} [/tex]

[tex]m = \frac{0}{15} [/tex]

Then we solve for the equation of the line by using the formula

[tex](y - y1) = m(x - x1)[/tex]

but we have only y1, m and x1 so we substitute given us

[tex](y - 1) = \frac{0}{15} (x - ( - 8))[/tex]

but also, we must get rid of the fraction 0/15

so we multiply through by the denominator 15

[tex]15 \times (y - 1) = 15 \times \frac{0}{15} (x - (8))[/tex]

we get

[tex]15(y - 1) = 0(x - ( - 8))[/tex]

now we expand all brackets

[tex]15y - 15 = 0[/tex]

but we want the equation so we make y stand alone

[tex]15y = 15 \\ \\ \frac{15y}{15} = \frac{15}{15} \\ \\ y = 1[/tex]

the equation of the line is y=1

The third coin also has a 1 in 2 or 1 2 chance of matching the coin on the first toss. Therefore the probability of tossing three coins and getting all heads or all tails is: 1 × 1 2 × 1 2 = 1 4 = 0.25 or 25% We can also show this from the results table below: There are 8 possible outcomes for tossing three coins.

The required, Jordan had to pay $53.03 in interest on her loan.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.

here,
To find the amount of interest Jordan had to pay, we can use the simple interest formula,

I = P  × r × t

Where I is the amount of interest, P is the principal (the initial amount of the loan), r is the annual interest rate as a decimal, and t is the time in years.

In this case, P = $850, r = 0.0575 (5.75% expressed as a decimal), and t = 14/12 (since the loan was for 14 months, which is 1 year and 2 months or 1.16667 years).

Substitute the value in equation 1.

I = $850 × 0.0575 × 14/12

= $57.02

Therefore, Jordan had to pay $53.03 in interest on her loan.

Answer:

Step-by-step explanation:

hello :

the coordinates of the point on the unit circle at the given angle.-225°:

x= cos(-225°)= -√2/2

y = sin (-225°)= √2/2

The coordinates of the point on the unit circle at an angle -225°° are [tex](\frac{-\sqrt{2} }{2} , \frac{\sqrt{2}} {2} )[/tex].

" The coordinates of the point is defined as the pair of such points which represents the exact location of the point."

" Unit circle means a circle with radius equals to 1unit."

Formula used

Equation of the circle with center (0, 0) and radius r

[tex]x^{2} +y^{2} =r^{2}[/tex]

Coordinates of the point on the circle (rcosθ , rsinθ)

cos(-θ) = cosθ

sin (-θ) = -sinθ

cos ([tex]\frac{3\pi }{2}[/tex] -θ) = -cosθ

sin ([tex]\frac{3\pi }{2}[/tex] -θ) = -sinθ

According to the question,

Given θ = -225°

Unit circle 'r' = 1

Therefore Coordinates are,

'x' coordinates represented by  rcosθ

'y' coordinates represented by  rsinθ

Substitute the value of r and θ in the coordinates of the point we get,

x = rcosθ

 = 1 × cos (-225°)

 = cos (225°)

 = cos ( 270° - 45°)

 [tex]=cos(\frac{3\pi }{2} -\frac{\pi }{4} )[/tex]                      

[tex]= - sin(\frac{\pi }{4}) \\= - \frac{1}{\sqrt{2} } \\=-\frac{\sqrt{2} }{2}[/tex]

y = rsinθ

 = 1 × sin (-225°)

 = -sin (225°)

 = -sin ( 270° - 45°)

 [tex]=-sin(\frac{3\pi }{2} -\frac{\pi }{4} )[/tex]                      

[tex]= -( - cos(\frac{\pi }{4})) \\= \frac{1}{\sqrt{2} } \\=\frac{\sqrt{2} }{2}[/tex]

Hence, coordinates of the point on the unit circle at an angle -225°° are [tex](\frac{-\sqrt{2} }{2} , \frac{\sqrt{2}} {2} )[/tex].

Answer:

The value of x is all real numbers.

Step-by-step explanation:

4(2x -1) + 8 -14x = -8x + 4 + 2x <== distribute 4

4(2x) + 4(-1) + 8 -14x = -8x + 4 + 2x

8x - 4 + 8 -14x = -8x + 4 + 2x <== combine any like terms on both sides

-6x + 4 = -6x + 4 <== both sides are equal

Since both sides of the equation are equal, this means that any x value makes the equation true. Any real number can be used as the value of x.

Answer:

Step-by-step explanation:

The probability of getting both fashion and health magazine without replacement is 2/7.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a shelf contains 3 fashion magazines and 4 health magazines.

Total number of books = 7

Number of fashion magazines = 3

Number of health magazines= 4

Probability of getting fashion magazines = 3/7

Probability of getting health magazines = 4/6

Probability of getting both the events = 3/7 ×4/6

= 1/7 ×4/2

= 2/7

Therefore, probability of getting both fashion and health magazine without replacement is 2/7.

Step-by-step explanation:

the area of a circle is

pi×r²

the lateral area of a cylinder is the area only if the "mantle" of the cylinder : the round area all around the cylinder in its side.

in other words : everything but the ground and the top area.

how can we get the area of the side "mantle" ?

we can imagine, we take a knife and cut a straight line (and at 90°) from the top to the bottom, and then cut off the ground and the top circles by cutting along their circumference.

what do we get ?

if we put that remaining area in the table and press it flat, it is ... a rectangle. simply a rectangle.

its width is the height of the cylinder (the length of our initial top-bottom cut).

and its length is the length of the circle circumference that e just cut off.

and the circumference of a circle is

2×pi×r

so, the lateral area of the cylinder is

2×pi×r × h

r being the radius

h being the height of the cylinder.

and we get

LA = 2×pi×r×r = 882×pi

pi × r² = 441 × pi

r² = 441

r = 21 units²
