Answer:

It's equilateral. Equilateral triangles are three equal-sided polygons. Remember that. It helps.

Answer:

t=number of years since start of the study.

y=city´s population.

first year:

y=390,000+0.073(390,000)=390,000(1+0.073)    (=418470)

Second year:

y=(390,000(1+0.073)  + 0.073(390,000(1+0.073) =

=390,000(1+0.073) (1+0.073)

=390,000(1+0.073)²

 (≈449,018.31)

Third year: if you calculate it you would have:

y=390,000(1+0.073)³

Fourth year: if you compute it you would have:

y=390,000 (1+0.073)⁴

t th year:

y=390,000(1+0.073)^t

Answer: y=390,000(1+0.073)^t

Answer:

  4 : 1

Step-by-step explanation:

Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:

Answer:

-5 ≤x≤6

[-5,6]

Step-by-step explanation:

The domain is the values that the input takes

x goes from -5 (inclusive) to 6 (inclusive)

-5 ≤x≤6

[-5,6]

Answer:

[-5, 6]

Step-by-step explanation:

    The domain of a function is the list of x values. Since the endpoints are shaded, that means those x values are included as well. Therefore, the domain of f is [-5, 6].

Answer: 4

Step-by-step explanation:

(4,-2) will be point 1, (7,10) will be point 2. The order doesn't matter.

slope = y2-y1 / x2 - x1

slope = 10 - (-2) / 7 - 4

slope = 12 / 3

slope = 4

The slope of the line that passing through (4, -2) and (7, 10) is 11/3.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

(4, -1) = (a, b) and (7, 10) = (c, d)

Slope:

= (d - b) / (c - a)

= (10 + 1) / (7 - 4)

= 11 / 3

Thus,

The slope is 11/3.

Answer:

m'=7

Step-by-step explanation:

they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:

m = m'

y-4=7x+14

y=7x+18

y=mx+h

So m = 7

Answer:

The value of A is 2

Step-by-step explanation:

F = 2 , B = 3 , K = 10

K = F( A + B )

10 = 2(A + 3)

10 = 2A + 6

Now, Subtract 6 from each side we get,

10 - 6 = 2A + 6 - 6

4 = 2A

2A = 4

Now, divide both side by 2 we get,

2A/2 = 4/2

A = 2

Thus, The value of A is 2

K = F( A + B )

10 = 2(2 + 3)

10 = 2(5)

10 = 10

Answer:

The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.

Step-by-step explanation:

You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x

=> x = 50 m / tan(86°)

x = 50 m / 14.30 = 0.98 m

2 feet away from the building

Answer:

Distance = 5

Step-by-step explanation:

D= sqrt (x1-x2)^2 + (y1-y2)^2
