A"(-1, -3), B"(-2, -6), C"(1,-7)

Step-by-step explanation:

y= -4 is a horizontal line that cuts y-axis at (0, -4)

A'(-4, -5), B'(-5,-2), C'(-2,-1) are given on thhe graph

first we reflect over the line m, y= -4

A"(-4, -3), B"(-5, -6), C"(-2,-7) because the line m is the bisector of what conects the image and preimage points

second we translate T(3,0) so you add a 3 to the x coordinate of each point

A"(-4+3, -3), B"(-5+3, -6), C"(-2+3,-7)

if cos(x)=-1/4 and tan(x)<0 what is sin(2x)

Answers

By definition of tangent,

tan(x) = sin(x) / cos(x)

so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.

Recall the Pythagorean identity:

cos²(x) + sin²(x) = 1 → sin(x) = + √(1 - cos²(x))

Then

sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4

Recall the double angle identity:

sin(2x) = 2 sin(x) cos(x)

Then

sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8

Answers

3 cups : 12 tbsp? I think is the right answer

The ratio of cups of flour to tablespoons of peanut butter if Felipe makes 3 batches of dog treats is, 1/4

What is the ratio?

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

Felipe makes 3 batches of dog treats

The recipe for peanut butter dog treats,

(Ingredient) (amount)

Peanut butter 4 tbsp

Flour 1 cup

Egg 1

Water 2 tbsp

For 3 batches

Peanut butter required = 3 × required for one batch

= 3 × 4

= 12 tbsp

Flour Required = 3 × required for one batch

= 3 × 1

= 3

the ratio of cups of flour to tablespoons of peanut butter = 3/12

= 1/4

Hence, the ratio is 1/4

Determine the value of x in the diagram below

Answers

Answer:

x =32

Step-by-step explanation:

create equation

180 = 3x + 20 + 2x

combine like terms

180= 3x + 20 + 2x

180=5x + 20

subtract 20 from both sides of the equation

180=5x + 20

180-20= 5x +20 -20

simplify

160= 5x

divided both sides by 5

160/5=5x/5

The spoke of a wheel is 35 cm. How far does the wheel travel in 1 rotation. Give your answer in meters and use pi = 22/7.

Answers

Answer:

2.2 m

Step-by-step explanation:

Assuming that spoke refers to the radius (r) of the wheel, you can determine the circumference of the wheel using 2(pi)(r).

2 x (22/7) x 35cm

= 220cm

As this answer is in cm, it needs to be converted to m to be a correct answer. As 1m = 100cm, 220cm x 0.01 = 2.2m
