Answer:

Option B

Step-by-step explanation:

Equation of the graph,

f(x) = x²

If the graph is translated 5 units to the right,

g(x) = f(x - 5)

Therefore, g(x) = (x - 5)²

If the function 'g' is translated 3 units up,

h(x) = g(x) + 3

Therefore, h(x) = (x - 5)² + 3

If the function 'h' is vertically compressed by a factor of $\frac{2}{3}$ ,

Then the new function will be,

k(x) = $\frac{2}{3}(x-5)^2+3$

Option B will the correct option.

Component form of u is (-18,13) and The magnitude of u is 22.2

<h3>What is a vector?</h3>

A vector is a two-dimensional entity with both magnitude and direction. A vector can be visualized geometrically as a directed line segment.

The component form of a vector is an ordered pair that describes the change in x and y values

This is mathematically expressed as (Δx, Δy) where Δx=x₂-x₁ and Δy=y₂-y₁

Given ;

Initial points of the vector as (14,-6)

The terminal point of the vector is (-4,7)

Here x₁=14,x₂=-4, y₁=-6,y₂=7

The component form of the vector u is (-4-14,7--6) =(-18,13)

Finding the Magnitude of the vector

u=√(x₂-x₁)²+(y₂-y₁)²

u=√-18²+13²

u=√324+169

u=√493

u=22.2

Therefore the Component form of u is (-18,13) and The magnitude of u is 22.2

I NEED HELP IDENTIFYING THE SLOPE PLEASE !!! Pic attatched !!!!

Alexus [3.1K]

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = 2,4 ) and (x₂, y₂ ) = (5, 1)

m = $\frac{1-4}{5-2}$ = $\frac{-3}{3}$ = - 1 ← negative slope

Repeat

with (x₁, y₁ ) = - 7,8) and (x₂, y₂ ) = (- 7, 0)

m = $\frac{0-8}{-7+7}$ = $\frac{-8}{0}$

Division by zero is undefined, thus slope is undefined.

Repeat with

(x₁, y₁ ) = (6, - 3) and (x₂, y₂ ) = (- 4, - 3)

m = $\frac{-3+3}{-4-6}$ = $\frac{0}{-10}$ = 0 ← zero slope

Repeat with

(x₁, y₁ ) = (3, 5) and (x₂, y₂ ) = (- 1, 2)

m = $\frac{2-5}{-1-3}$ = $\frac{-3}{-4}$ = $\frac{3}{4}$ ← positive slope

FACTOR !!!<br><br> a) 5x^2+25 <br><br> b) 2x^2-3x-2

Mademuasel [1]

Step-by-step explanation:

(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).

(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2

= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).

Please help? This is complicated

D,

You basically see if statements are correct or not. Remember this is sample, sample is portion of population so if everything is dome correctly, the results of sample will also display the results of population +- error (standard deviation). So you can just use the sample results to answer questions about the population.

A is correct because social studies has 4 students and reading has 8. Math has twice.
B is correct because reading has 2 and math has 8. Reading is one fourth of math 8*1/4 = 8/4=2.
D is NOT correct because math is 8, social studies is 4. Math is not half of social studies. Social studies is half of math.
