For the first 3 years of a horse's life, the weight, w (in kilograms), of the horse approximately fits the formula w(t)=30+170t, where t is the age of the horse in years. Which of the following is the most accurate interpretation of the slope of the line represented by this formula? A. The slope is 170. This means that the horse gains an average of 170 kilograms per year for the first 3 years of its life. B. The slope is 30. This means that the horse gains a total of 30 kilograms in the first 3 years of its life. C. The slope is 30. This means the horse gains on average 30 kilograms per use for the first 3years of its life. D. The slope is 170. This means that the horse gains a total of 170 kilograms in the first 3 years of its life.

In ΔOPQ, p = 180 inches, q = 120 inches and ∠O=171°. Find the length of o, to the nearest inch.

Answers

Given:

In ΔOPQ, p = 180 inches, q = 120 inches and ∠O=171°.

To find:

The length of o, to the nearest inch.

Solution:

According to cosine formula,

$a^2=b^2+c^2-2bc\cos A$

Using cosine formula in ΔOPQ, we get

$o^2=p^2+q^2-2pq\cos O$

On substituting the values, we get

$o^2=(180)^2+(120)^2-2(180)(120)\cos (171^\circ)$

$o^2=32400+14400-43200(-0.9877)$

$o^2=46800+42668.64$

$o^2=89468.64$

Taking square root on both sides.

$o=√(89468.64)$

$o=299.113$

$o\approx 299$

Therefore, the length of o is about 299 inches.

yvonne has a goal of buying a brand new home within a year. she’s afraid that she will be unable to save the money that she needs for a down payment. which of the following should not be part of yvonne’s plan for achieving her goal of buying a home?

Answers

B. borrow the money for the down payment and pay it back later

Answer:

The correct option is B.

Step-by-step explanation:

If she borrowing money from somewhere else will increase pressure on her financially as she will have to pay the amount of interest along with the principle amount that she is borrowing.

This can result in increasing the pressure on her mentally and financially.

Rest all the other options will motivate her to save money for the house she wants to have without putting her into any kind of pressure.

Therefore the correct option is B.

∠A = 106.3°, ∠B = 20.6°, ∠C = 53.1°

Step-by-step explanation:

In a ΔABC, the sides opposite to the angle A is a, angle B is b, and angle C is c. a = 60 , b= 22, c = 50

We can find any one angle by cosine rule,

a² = b² + c² - 2 bc cos (A)

60² = 22² + 50² - 2(22)(50) cos A

3600 = 484 + 2500 - 2200 cos A

3600 = 2984 - 2200 cos A

3600 - 2984 = -2200 cos A

616 = -2200 cos A

cos A = 616/ -2200 = -0.28

A = cos⁻¹ (-0.28) = 106.3°

Now we can use sine rule to find angle B as,

sin A/ a = sin B / b

sin 106.3° / 60 = sin B / 22

sin B = 22 × sin 106.3° / 60

B = sin⁻¹ (22 × sin 106.3° / 60 ) = 20.6°

As we know the sum of angles in a triangle is 180°.

∠A + ∠B + ∠C = 180°

106.3° + 20.6° + ∠C = 180°

126.9° + ∠C = 180°

∠C = 180° - 126.9° = 53.1°

Find the slope of the line that passes through the points (-8,-3) and (2, 3)0
1
3/5
5/3

Answers

Answer:

The answer is

$(3)/(5)$

Step-by-step explanation:

To find the slope passing through two points we use the formula

$m = (y2 - y1)/(x2 - x1)$

Where

m is the slope

( x1 , y1) and ( x2 , y2) are the points

From the question the points are

(-8,-3) and (2, 3)

So the slope is

$m = (3 + 3)/(2 + 8) = (6)/(10) = (3)/(5)$
