Write the standard form of the equation of the line through the given point with the given slope. point (-1.0); slope -2/3​

Answers

Answer:

Step-by-step explanation:

When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)

which here becomes:

y - 0 = m(x + 1), or y = (-2/3)(x + 1), or  y = (-2/3)x - 2/3

If you want this in standard form, first clear the fractions by multiplying all terms by 3:  3y = -2x - 2

Now add 2x to both sides, obtaining:  2x + 3y = -2 (in "standard form."

Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students' nets is true?

Answers

Complete question is;

Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students’ nets is true? Both nets do not form octagonal prisms.

A) Only Alejandro’s net is correct.

B) Only Noya’s net is correct.

C) Neither net is correct.

D) Both nets are correct.

Answer:

C) Neither net is correct.

Step-by-step explanation:

From the second attached image, we can see what an octagonal prism looks like when it is opened to show all the faces.

However, looking at the first attached image showing the net drawings of boya and Alejandro, it is very clear that none of them got the required shape for the octagonal prism. Therefore, we can conclude that neither of the nets are correct.

For a school fundraiser, Percy bought a big box of rubber ducks and wrote prize amounts, in dollars, on the bottom of each rubber duck. The prize amounts were $5, $10, $20, $50, and $100. The number of ducks with each prize amount varied so that the total value for all the ducks with each prize amount was always $500.

Percy then put all the rubber ducks in his school’s swimming pool. At the fundraiser, participants used a long net to catch a duck from the pool. They won the amount written on the bottom of the rubber duck, and then they threw the duck back into the pool before the next person’s turn. Since the ducks were returned to the pool after they were caught, the chances of winning any particular amount remained the same.

since both intersecting lines are straight,
the angle opposite 45° also equals to 45°, as they are vertically opposite angles.

thus,
45°+45°+x+x = 360° (sum of angles at a point)
2x = 360°-90°
2x = 270°
x = 135°

He then took a random sample of 6 tests and calculated the minimum of the sample. He replaced those tests

functions

OB. AB) = x= 1962–31x-3
x-2
O C. FX) =

Answers

Given:

The graph of rational function.

To find:

The rational function.

Solution:

If the graph of a rational function has a vertical asymptote at [tex]x=a[/tex], then [tex](x-a)[/tex] must be a factor of the denominator of that rational function.

From the given graph it is clear that the graph has two vertical asymptotes. One is at [tex]x=-1[/tex] and another one is at [tex]x=3[/tex].

It means, [tex](x-3)[/tex] and [tex](x+1)[/tex] are the only two factors of the denominator of the rational function.

In option A, the factors of the denominator are different from [tex](x-3)[/tex] and [tex](x+1)[/tex] .

In option B, the denominator has an extra factor [tex]x-2[/tex].

In option C, the denominator has only two factors [tex](x-3)[/tex] and [tex](x+1)[/tex].

Therefore, the correct option is C.

Suppose you invest $4,600 into a savings account with a 8.25% annual interest rate
that compounds interest monthly. Use the TVM solver on your calculator to find the
future value of the account after ten years.

NEED ANSWER ASAP

Answers

Answer:

$10,467.06

Step-by-step explanation:

The computation of the future value is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

here

rate of interest = 8.25% ÷ 12 = 0.6875%

And, the number of years is = 12 × 10 = 120

So, the future value is

= $4,600 × (1 + 0.6875%)^120

= $4,600 × 2.275448086

= $10,467.06

Answer:

[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{24}[/tex]

Step-by-step explanation:

To get the sine of a non-right angle C in a right triangle, just divide the side opposing C by the long side. To get the cosine, divide the sides at C (shorter by longer). To get the tangent, divide the sine by the cosine.

Let's go:

[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{25} / \frac{24}{25} = \frac{7}{24}[/tex]

Answer:

sin(7/25), cos(24/25), tan(7/24)

Step-by-step explanation:

The sin, cos, and tan are found through the sides of the triangle.

The acronym SOH CAH TOA can be used to find which goes where.

S = sin

C = cos

T = tan

O = opposite

A = adjacent

H = hypotenuse

since it asks to use  angle C you start from there, for sin its O/H hint by the SOH the rest are the same.
