What is (f + g)(x)?
f(x) = -3x^2
g(x) = -5x + 4

What Is (f + G)(x)?f(x) = -3x^2g(x) = -5x + 4

Answers

Answer 1

Answer:

x=4 and y= 2/3

Step-by-step explanation:

g(x)= -5x+4

g(0)= -5(0)+4

=4

(0,4)

then you find x

1(x)= -5x+4

x= -5x+4

x+5x = 4

6x ÷ 6 =4÷6

x = 2/3 or ⅔

World Gym has an initial fee of $100 and $50 per month. Flex Gym has an initial fee of $200 and $25 per month. How many months will it take
until you would pay the same amount to join at both gyms?
a. 4 months
b. 5 months
C. 2 months
d. 6 months

Answers

answer:

a. 4 months

step-by-step explanation:

set up an expression for each and put them equal to each otherthis is the way you can use to solve these kinds of problemsbreak down the question into parts

m stands for months

world gym = 100 + 50m

flex gym = 200 + 25m

now put them equal to each other to know how many months it will take to pay the same amount to join

100 + 50m = 200 + 25m

50m = 100 + 25m

25m = 100

m = 4

this means it will take 4 months to pay the same amount to join

To prove that VWZ~ YXZ by the SAS similarity
theorem, which other sides or angles should be used?

Answers

To prove that △VWZ ~ △YXZ by SAS theorem, we must prove that two of the sides for each triangle is congruent, and the angle inbetween the sides are congruent. Depending on which side is given to you, choose the one that conforming to it.

Let △ABC be a right triangle with m∠C = 90°. Given tan ∠B = 1, find tan ∠A.

Answers

The value of tan∠A form the right angled triangle ABC is 1.

Trigonometric ratio

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Given that △ABC be a right triangle with m∠C = 90°. Also, tan∠B = 1. Hence:

tan∠A = (tan∠B)⁻¹ = 1

Step-by-step explanation:

Right off the bat, we know that each drink is $1.50. So buying two would be $3 so far. Subtract $3 from $49.50. Getting $47.50. Now we know the drinks so we must divide 47.50 by 7.25, equalling 6.5 and so on. To round it we can say 6 bowls.

if cos theta + sin theta = root 2 cos thetha prove that cos theta - sin theta = root 2 sin theta
​

Answers

Answer:

We have:

If:

Cos(θ) + Sin(θ) = √2*cos(θ)

We want to prove that:

Cos(θ) - Sin(θ) = √2*Sin(θ)

Well, let's start with the first relation:

Cos(θ) + Sin(θ) = √2*cos(θ)

Now we can subtract 2*Sin(θ) and we will get:

Cos(θ) + Sin(θ) - 2*Sin(θ) = √2*cos(θ) - 2*sin(θ)

Cos(θ) - Sin(θ) = √2*cos(θ) - 2*sin(θ)

Now, we also can rewrite the first equation as:

Cos(θ) + Sin(θ) = √2*cos(θ)

Cos(θ) - √2*cos(θ) = -  Sin(θ)

Cos(θ)*( 1 - √2) = -Sin(θ)

Cos(θ) = -Sin(θ)/( 1 - √2) = Sin(θ)/(- 1 + √2)

We can replace this in the right side of theequation:

Cos(θ) - Sin(θ) = √2*cos(θ) - 2*sin(θ)

Cos(θ) - Sin(θ) = √2* Sin(θ)/(- 1 + √2) - 2*sin(θ)

Cos(θ) - Sin(θ) = (√2/(- 1 + √2) - 2)*Sin(θ)

Now we have this:

√2/(- 1 + √2)) - 2 = a

if we multiply all by (-1  + √2) we get:

√2 - 2*(-1  + √2) = a*(-1  + √2)

√2  + 2 - 2*√2 =  a*(-1  + √2)

2 - √2 = a*(-1  + √2)

√2*(√2 - 1) = a*(-1  + √2)

√2*(√2 - 1)/(-1  + √2) = a

√2 = a

Then:

√2/(- 1 + √2)) - 2 = √2

If we replace this in the equation:

Cos(θ) - Sin(θ) = (√2/(- 1 + √2) - 2)*Sin(θ)

We get:

Cos(θ) - Sin(θ) = √2*Sin(θ)

Which is the thing we wanted to get.

Identify the relationship between angles x and y

Answers

Answer:

Therefore the two angles labelled x are equal. Also, the two angles labelled y are equal. We know that x, y and z together add up to 180 degrees, because these together is just the angle around the straight line. So the three angles in the triangle must add up to 180 degrees.

A ladder is 6 m long.
The ladder is placed on horizontal ground, resting against a vertical wall.
The instructions for using the ladder say that the bottom of the ladder must not be closer than 1.5 m
from the bottom of the wall.
How far up the wall can the ladder reach?

Answers

Answer:

5.8 m

Step-by-step explanation:

Using the Pythagorean Theorem (a² + b² = c²) you get the equation a² + 1.5² = 6² (or 1.5² + b² = 6²). Then you solve from there and rounding to the first decimal place you get 5.8

The ladder can reach a height of 5.6 meters.

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a ladder that is resting against a wall.

Now, assume that the ladder can reach a height of [x] meters. Then when  the bottom is at a horizontal distance of 1.5 meters, then we will get a right angled triangle with base = 1.5 m and hypotenuse = 6m. So, using Pythagoras theorem, we can write -

(6 x 6) = x² + (1.5 x 1.5)

x² = (6 x 6) - (1.5 x 1.5)

x² = 7.5 x 4.5

x² = 33.75

x = 5.6 meters

Therefore, the ladder can reach a height of 5.6 meters.
