A triangle has an angle that measures 25. The other two angles are in a ratio of 11:20. What are the measures of those two angles?

Answers

Answer:

The measures of the two angles are 55 and 100 degrees.

Step-by-step explanation:

The three interior angles of a triangle always add up to 180.

So if one angle is 25 degrees

180 - 25 = 155

The two other angles must add up to 155.

If the ratio is 11:20

That means there are 31 equal parts between the two angles

So 155/31 =5

Whic means

11 x 5 = 55

20 x 5 = 100

The two missing angles are 55 and 100 degrees.

Hope this explanation helped you!

Given that sin 42° ≈0.669, enter the cosine of a complementary angle.

Answers

Answer:

0.01167

Step-by-step explanation:

180 - 0.669 = 89.331

complementary angle = 89.331

cos(89.331) = 0.01167

Carmen runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

Answers

Answer:

4.2 miles

Step-by-step explanation:

6 miles/50 minutes = x miles/35 minutes

1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5

2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:

0.6/5 = 4.2 miles/35 minutes

-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False

Answers

Answer:

true

Step-by-step explanation:

If x = - 3 is a zero of the polynomial then f(- 3) = 0

f(x) = x³ + 7x² + 16x + 12

     = (- 3)³ + 7(- 3)² + 16(- 3) + 12

     = - 27 + 63 - 48 + 12

     = 0

Since f(- 3) = 0 then x = - 3 is a zero of the polynomial

Choose the function that correctly identifies the transformation of f(x) = x2 shifted three units to the left and five units up.
og*) = (x - 3)2-5
og(x) = (x - 3)2 + 5
og(x) = (x + 3)2 + 5
o g() = (x + 3)2-5

Answers

I just learned this today. I think the answer would be c because if it is in Parentheses, it will go to the right or left depending on if it’s positive or negative and if it’s outside parentheses it will go up or down depending on if it’s positive or negative

The functions that correctly identify the transformation of f(x) = x² shifted three units to the left and five units up is

g(x) = (x + 3)² + 5

Option C is the correct answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The function that correctly identifies the transformation of f(x) = x² shifted three units to the left and five units up is:

g(x) = (x + 3)² + 5

To see why, we can use the following steps:

To shift a function three units to the left, we replace "x" with "(x + 3)".

This is because for any value of "x", "x + 3" represents a point that is three units to the left of "x".

To shift a function five units up, we add 5 to the entire function.

This is because for any value of "x", the value of the function is increased by 5 units.

Combining these transformations, we get:

g(x) = (x + 3)² + 5

This function represents a parabola that is shifted three units to the left and five units up from the original function f(x) = x^2.

Thus,

The functions that correctly identify the transformation of f(x) = x² shifted three units to the left and five units up is

g(x) = (x + 3)² + 5

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

Given that,

The total number of pies is 1,954.

Number of types of pie = 2.

Each type of bakery can be found by taking the ratio of the number of pies and number of types of pie as follows,

1954/2

= 977

Hence, the number of each type of pie made by the bakery is 977.

a quadratic function that fits the points (0,5) (2,3) (4,9)

Answers

Answer:

Step-by-step explanation:

y=ax^2+bx+c we are given point (0,5) so if x=0, y=c, so c=5. We have two other points

(2,3)(4,9) which gives us

4a+2b+5=3 and 16a+4b+5=9

Subtracting twice the first from the second

16a+4b+5-8a-4b-10=9-6

8a-5=3

8a=8, so a=1, so using 4a+2b+5=3 we get

4(1)+2b+5=3

2b+9=3

2b=-6

b=-3 so our quadratic is

y=x^2-3x+5
