Answers

Answer:

yes

Step-by-step explanation:

the ratio of 28 : 36 can be simplifeid by dividing both sides of the ratio by 4.

28/4=7

36/4=9

so the ratio of 28 : 36 is equal to 7 : 9

The regular polygon has radii and an apothem as shown. Find the measure of each numbered angle.

Answers

9514 1404 393

Answer:

  ∠5 = 60°

  ∠6 = 30°

  ∠7 = 120°

Step-by-step explanation:

Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)

  ∠5 = 60°

  ∠6 = 30°

  ∠7 = 120°

Simplify, then write the answer in the standard form

Helga and Dora were solving the following problem together. A boat left Kyuquot and headed west at 15.5 km/h. A second boat left Kyuquot half an hour later and headed west at 18 km/h. For how many hours did the first boat travel before the second boat overtook it? Both girls used t to represent the time taken by the first boat. However, they disagreed on the equation to model the situation. Helga’s Equation Dora’s Equation 15.5t = 18(t + 0.5) 15.5t = 18(t - 0.5) a) Explain what the expression on each side of each equation represents. b) Which equation is correct? Explain. c) What is the solution to the problem?

Answers

Answer:

15.5t=18(t-0.5) is the correct answer

Step-by-step explanation:

if the first boat travels t time then the second traveld t-0.5 time to take over

The expression on each side of each equation represent the distance travelled. Hence, 15.5t=18(t-0.5) is the correct answer

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that boat left Kyuquot and headed west at 15.5 km/h.

A second boat left Kyuquot half an hour later and headed west at 18 km/h.

Helga’s Equation 15.5t = 18(t + 0.5)

Dora’s Equation 15.5t = 18(t - 0.5)

Therefore, if the first boat travels t time then the second travelled

t-0.5 time to take over

Which graph represents an exponential function?

Answers

An exponential function has a graph that is a smooth curve; it either increases at an ever increasing rate or decreases at an ever increasing rate. The only graph that fits these characteristics is the first one.

Suppose all the terms of a geometric sequence are
positive, and the common ratio r is between 0 and
1.
Is the sequence increasing of decreasing? Explain.

Answers

Answer: the sequence is increasing. The reason it is increasing because its atleaset increasing by one number.

Answer:

Step-by-step explanation:

this is called  "monotonically decreasing"    as the exponent on the ratio goes up , and the ratio is less than 1 but more than zero,  the number gets smaller and smaller.... it approaches zero is what happens.

Answer:

Step-by-step explanation:

You are given the area and base lengths of a trapezoid and asked for its height. The formula for the area of a trapezoid is useful.

  A = (1/2)(b1 +b2)h

Filling in the given information, you have ...

  30 ft² = (1/2)(4 ft +8 ft)h

  30 ft² = (6 ft)h . . . . . . . . . . . simplify

  h = (30 ft²)/(6 ft) = 5 ft . . . . divide by the coefficient of h

The height of the trapezoid is 5 feet.

The graph of linear function f passes through the points (-8,-2) and (4,4). What is the x-intercept of f?

Answers

Answer:

2

Step-by-step explanation:

X= 2

just make a graph and you got the answer

.

The value of the x-intercept if f passes through the points (-8,-2) and (4,4), is -4 and the equation of the line is 2y -x = 4.

What is function?

Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.

Given:

The graph of linear function f passes through the points (-8,-2) and (4,4),

Calculate the equation of the line as shown below,

y - 4 = [4-(-2) / 4 - (-8)](x - 4)

y - 4 = 6 / 12 (x - 4)

y - 4 = 1/2 (x - 4)

2y - 8 = x - 4

2y -x = 4

Calculate the x-intercept by putting y = 0,

0 × 2 - x = 4

x = -4

Thus, the value of x is -4.

what is the lateral of a cone with 10 yd and 12.1 yd

Answers

Answer:

190.07 yd²

Step-by-step explanation:

Given that :

Base of cone = 10 yards

Height of cone = 12.1 yards

The lateral area of a cone is obtained using the relation :

π × r * l

Where r = Radius = base / 2

l = height of cone

Radius, r = 10/ 2 = 5 yards

Lateral area = π * 5 * 12.1

Lateral area = 190. 0666

Lateral area = 190.07 yd²

Evelyn is going to invest $3,500 and leave it in an account for 16 years. Assuming the interest is compounded quarterly, what interest rate, to the nearest tenth of a percent, would be required in order for Evelyn to end up with $6,200?

Answers

Answer:

Quarterly interest rate= 0.8974%

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $3,500

Future Value (FV)= $6,200

Number of periods (n)= 16*4= 64 quarters

It is almost impossible to calculate the interest rate using a formula. To determine the interest rate, we need to use a financial calculator:

Function: CMPD

n= 64

I%= SOLVE= 0.8974

PV= 3,500

FV= -6,200

Quarterly interest rate= 0.8974%

If f(x) = 3x - 1 and g(x) = x + 2, find (f+ g)(x).

Answers

Answer:

4x+1

Step-by-step explanation:

Since you're finding (f+g) (x), it means you are adding f(x) and g(x) together.

so you add: (3x-1) and (x+2)

combining like terms, you get 4x and 1, which means (f+g)(x)= 4x+1

Answer:

(f + g)(x) = 4x + 1

Step-by-step explanation:

(f + g)(x) - f(x) + g(x) = 3x - 1 + x + 2 = 4x + 1
