If f(x) = 3x2 + 2x - 2, find f(8) - f(-5)

Answers

Answer 1

Answer: 143

Step-by-step explanation:

f(8) = 3(8)^2 + 2*8 - 2 = 3*64 + 16 - 2 = 192 + 16 - 2 = 206

f(-5) = 3(-5)^2 + 2*(-5) - 2 = 3*25 + (-10) -2 = 75 - 10 - 2 = 63

f(8) - f(-5) = 206 - 63 = 143

The lengths of a side of a triangle are 12.1 inches, 11.28 inches, and 5.4 inches. What is
the perimeter of the triangle?

Answers

Answer:

28.78

Step-by-step explanation:

12.1+11.28+5.4=28.78

To find a perimeter, you would add up all of the sides. There are 3 sides so you would add them all up to get 28.78

For parallel lines, gradients (slope) must be the same.

The lines given in multiple choice, no line with the same gradient/slope as line y = 3x - 2.

Step-by-step explanation:

From y = 3x - 2,

The slope = 3

Let's check slopes of lines from multiple choice:

From first line

4x + 2y = 5

2y = -4x + 5 (dived 2 both sides)

y = - 2x + 5/2

The slope = -2

Continue with remaining three equations you get slopes: -1/2, -4 and 4.

Hence no equations above represent parallel equation to y = 3x - 2

The quotient of fifty and five more than a number is ten

Answers

Answer:

This number would be straight out zero  .

Step-by-step explanation:

First it said the quotient of fifty and five MORE than a number is 10, so we first need to focus on the line five MORE than a number is 10, so we know this number is less than the value used in the equation then we focus on the quotient of fifty and, So we know this unknown number lets just say the variable for it is n, then we know that fifty/ n+5=10. So Lets use the associative property to turn this into and some algebra to fifty/10 = n+5, so 50/10 equals to 5, so we know that, 5= n+5, so that would be... n =  0.

it is expected that gas prices will rise to be 142% of the current amount. If the current gas price is $4 per gallon, explain how to estimate the expected price of gas.

Answers

The answer is 54 iybiybyibyib

Answer:

$5.68

Step-by-step explanation:

142% of the current price of $4 per gallon is found by multiplying these numbers:

 142% × $4.00/gal = $5.68/gal

_____

Of course, you know that 142% = 142/100 = 1.42. The numbers get multiplied and the units ($/gal) get applied to the result.

Multiplication by 4 is easily done mentally by doubling twice:

 4×1.42 = 2×(2×1.42) = 2×2.84 = 5.68

If the perimeter of this isosceles triangle is at most 45 centimeters, which inequality could be used to find the value of p?
4p - 6 < 45
7p - 12 < 45
6p - 12 < 45
5p - 6 < 45

Answers

Answer:

Step-by-step explanation:

7p-12< 45

_

The inequality that can be used to find p is 7p -12 < 45. The correct option is B.

What is a Triangle?

A triangle is a polygon with three sides, three angles, and three vertices.

The perimeter of the given triangle is at most 45 centimeters.

The perimeter of a triangle is equal to the sum of all sides

The sides given is 3p-6 , 3p-6 ,p

So,

3p-6 +3p-6 +p < 45

7p -12 < 45

Therefore, the inequality that can be used to find p is 7p -12 < 45. The correct option is B.

Determine if both triangles are congruent or not. Label the triangles as SSS, AAS, ASA, SAS, HL, or not enough information.

Answers

△ABD and △BCD are congruent as:

∠CBD = ∠ABD (Equal Angles)

BD = BD (Common side)

The 90 degree angle (Common between both triangles)

Therefore

△ABD ≅ △BCD (By AAS)

Answer:  ASA (angle side angle)

The diagram is not drawn to scale and it appears misleading since AD appears shorter than DC. However, the smaller triangles are congruent and we can prove it using ASA.

The tickmarks on the angles show we have a pair of congruent angles. The other pair of congruent angles are the two right angles (angle BDC and angle ADB). The pair of congruent sides are DB = DB. We use the reflexive property here. The sides are between the congruent angles mentioned. So we'll use ASA and not AAS.

-------------

Extra info:

We can't use SSS because we only have info about one pair of sides. SAS won't be used either for the same reason. HL = hypotenuse leg, and it applies to right triangles only. We don't have any info about the hypotenuse of either triangle, so we can't use this either.

Every 1 inch of vertical rise, 12 inches ramp length is required. What is the ramp length required for the rise of 10.5?

Answers

Answer:

You will require 126 inches of ramp for a rise of 10.5

Step-by-step explanation:

Evaluate the word problem

If your verticle rise is 10.5 inches for every 1 inch of that 10.5 you have 12 inches. This is written into an equation as follows;

x: How many inches of vertical rise you have,

y: Length of ramp required

y = 12x

Solve:

y = 12x

y = 12(10.5)

y = 126 inches of ramp
