Answer:

m∠A = 106°

Step-by-step explanation:

All three sides of the triangle are given in the question.

To find the measure of included angle A between two sides we will apply cosine formula,

BC²= AB² + AC² - 2(AB)(AC)cosA

(13)² = (10)² + (6)² - 2(10)(6)cosA

169 = 100 + 36 - 120cosA

cosA = [tex]\frac{-169+136}{120}[/tex]

cosA = -0.275

A = [tex]\text{cos}^{-1}(-0.275)[/tex]

A = 105.96°

A ≈ 106°

Therefore, m∠A = 106° will be the answer.

Answer:

-a > -b

Step-by-step explanation:

On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).

The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.

If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.

So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.

Example: let a = 3 and b =5.  

It is true that 3 < 5.

But it is NOT true that -3 < -5. It's the other way around!

-5 < -3

So, if a < b, then -a > -b.

I hope this brainliest, for 5 stars.

Step-by-step explanation:

The coordinates of line is (0, -3), (1, -1) and (2, 1)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 2x - 3

Now, putting x=0

y= -3

and, x= 1

y= 2(1)-3

y = -1

and, x= 2

y=2 (2)- 3

y = 1

Hence, the coordinates of line is (0, -3), (1, -1) and (2, 1)

Answer:

40 sq feet

Step-by-step explanation:

(im bad at explaining)

1 x 2 = 2 sq ft

3 x 2 = 6 sq ft

4 x 12 = 48 sq ft

2 sq ft + 6 + sq ft = 8 sq ft

48 - 8 = 40

The amount of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle) = 40 ft².

Area of a rectangle = lenght × width.

The amount of square feet of outdoor carpet needed = area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)

The amount of square feet of outdoor carpet needed = 12 × 4 - (3 × 2 + 2 × 1)

The amount of square feet of outdoor carpet needed = 48 - (6 + 2)

The amount of square feet of outdoor carpet needed = 40 ft²

Answer:

1/16 = 0.0625 = 6.25% probability that the sum of the two rolls equals 5.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Die with 8 sides

This means that the total number of outcomes is [tex]T = 8^2 = 64[/tex]

Outcomes in which the sum of the two rolls is 5:

(1,4), (4,1), (2,3), (3,2)

4 desired outcomes, so [tex]D = 4[/tex]

What is the probability that the sum of the two rolls equals 5?

[tex]p = \frac{D}{T} = \frac{4}{64} = 0.0625[/tex]

1/16 = 0.0625 = 6.25% probability that the sum of the two rolls equals 5.

The probability that the sum of the two rolls equals 5 is 1/16

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

Given a single die with 8 sides (numbered 1, 2, 3, ... , 8) is rolled twice, the total outcome will be:

Total outcome = 8^2

Total outcome = 64

For the sum of two rolls, the expected outcome will be:

E = {(1, 4), (4, 1), (3, 2), (2, 3)}

n(E) = 4

Pr(sum of the two rolls is 5) = 4/64

Pr(sum of the two rolls is 5) = 1/16

Hence the probability that the sum of the two rolls equals 5 is 1/16

B) 29/6

C) 23/3

D) 16/5

Step-by-step explanation:

To make the proper fraction improper, first, multiply the whole number by the bottom number in the fraction, then add whatever number was on top of the fraction, so for A, multiply 2 (whole number) by 8 (number on the bottom of the fraction), then add 7 (number on top of the fraction)

Actually Welcome to the Concept of the Graphs and plots,

since the given equation is a parabolic equation graph, hence we substitute every value to get the value of variable y.

1.) if x = -5 ,then 25-30-7 => y = -12

2.) if x = -1 , then 1-6-7 => y = -12

3.) if x = -6 , then 36 -36 -7=> y = -7

4.) if x = 0 , then 0+0-7 => y = -7

hence all values are proved above
