PLS HELP ME W/ #8 ASAP

tiny-mole [99]

Answer:

x=2

TU:4(2)-1=7

UB: 3

TB: 10

Step-by-step explanation:

4x-1+2x-1=5x

6x-2=5x

6x=5x+2

subtract 5x from both sides

x=2

TU: (4x-1)

4(2)-1

8-1

TU:4(2)-1=7

UB: (2x-1)

2(2)-1

4-1

UB: 3

G(2) +7 What is the average rate of change of g over the interval -2.4)

solmaris [256]

Answer:

$Rate = 1$

Step-by-step explanation:

Given

$g(x) = x + 7$

Interval: (-2,4)

Required

Determine the average rate of change

This is calculated using:

$Rate = \frac{g(b) - g(a)}{b-a}$

Where:

$(a,b) = (-2,4)$

So, we have:

$Rate = \frac{g(4) - g(-2)}{4-(-2)}$

$Rate = \frac{g(4) - g(-2)}{4+2}$

$Rate = \frac{g(4) - g(-2)}{6}$

Calculate g(4) and g(-2)

$g(4) = 4 + 7 = 11$

$g(-2) = -2 + 7 = 5$

So:

$Rate = \frac{11 - 5}{6}$

$Rate = \frac{6}{6}$

$Rate = 1$

Hence, the average rate of change is 1

A beach ball rolls off a cliff and onto the beach. The height, in feet, of the beach ball can be modeled by the function h(t)=64

True [87]

You are given h(t) = 64–16t^2.

You need to find h(1.25).

Set up:

h(1.25) = 64 - 16(1.25)^2

Take it from here.

In a 30-60-90 triangle, the length of the side opposite the 30 degree angle is 8. Find the length of the side opposite the 60 de

nalin [4]

Answer:

The length of the side opposite the 60 degree angle 'c' = 4

Step-by-step explanation:

Step(i):-

Given data ∠A = 90° , ∠B = 60° and ∠C = 30°

Given data the length of the side opposite the 30 degree angle is 8

let 'a' = 8

step(ii):-

By using sine rule formula in properties of triangle

$\frac{a}{Sin A} = \frac{b}{Sin B} = \frac{c}{Sin C} = 2 R$

$\frac{a}{Sin A} = \frac{c}{Sin C}$

$\frac{8}{Sin 90} = \frac{c}{Sin 30}$

cross multiplication , we get

$\frac{8 X sin 30}{Sin 90} = c$

we know that trigonometry formulas

sin 30° = $\frac{1}{2}$ and sin 90°= 1

C = 8 X 1/2 = 4

conclusion:-

The length of the side opposite the 60 degree angle 'c' = 4
