Answer:

[tex]T(x)= 0.04x^2+64x+142[/tex]

Step-by-step explanation:

Sum of Functions

We are given the functions for the cost of two generators:

[tex]C(x) = 0.03x^2+26x+24[/tex]

[tex]K(x) = 0.01x^2+38x+118[/tex]

We are required to find the function for the sum of the costs of the two generators:

T(x)= C(x)+K(x)

We'll add both functions:

[tex]T(x)= 0.03x^2+26x+24+ 0.01x^2+38x+118[/tex]

To find the sum of both functions, we collect like terms:

[tex]T(x)= (0.03+0.01)x^2+(26+38)x+(24+118)[/tex]

[tex]\boxed{T(x)= 0.04x^2+64x+142}[/tex]

Answer:

Step-by-step explanation:

1). f(x) = 2x

   f(-3) = 2(-3) = -6

   f(1) = 2(1) = 2

   f(4) = 2(4) = 8

   Ordered pairs → (-3, -6), (1, 2), (4, 8)

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

    f(-3) = 2(-3) + 1 = -5

    f(1) = 2(1) + 1 = 3

    f(4) = 2(4) + 1 = 9

   Ordered pairs → (-3, -5), (1, 3) and (4, 9)

     x       -3        1        4      

    f(x)     -5       3        9

3). f(x) = -3x

Which congruence theorems can be used to prove AABR = AACR? Select three options.

A. HL
B. AS
C. SSS
D. ASA
E. AAS

Answers

HL because it's a right triangle

Answers:

A)  HL

B)  SAS (I'm assuming you meant to say SAS instead of AS)

C)  SSS

========================================================

Explanation:

The square angle marker tells us we have 90 degree angles. So these are right triangles.

Because we're dealing with right triangles, we could use HL which stands for "hypotenuse leg". The hypotenuse is AR for either triangle, and you could use either of these two pairs for the leg

AB = AC (one possible pairing), or,BR = CR (another possible leg pairing)

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

The tickmarks tell us which sides are the same length. We can see that

AB = AC (single tickmark)BR = CR (double tickmarks)

We also know that angle ABC = angle ACR because all right angles are congruent. These facts allow us to use SAS (side angle side). I'm assuming you meant to say "SAS" instead of "AS" for choice B.

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

SSS stands for "Side Side Side". It means if we know that three pairs of sides are congruent, then we can prove the triangles congruent overall.

The three pairs of congruent sides are:

AB = AC (single tickmark)BR = CR (double tickmarks)AR = AR (shared overlapped side; reflexive property)

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

Side notes:

We can rule choice D out because we don't have enough info to use ASA. We would need info about another pair of congruent angles.Similarly, AAS can't be used either. We only have info about one pair of angles (not two). So we can rule out choice E.

For each sequence find the first four terms and the tenth term 3n-4

Answers

Answer:

= 1, 2, 5, 8 and 26

Step-by-step explanation:

To find the first 4 terms, substitute n = 1, 2, 3, 4 into the formula

a₁ = 3(1) - 4 = 3 - 4 = - 1

a₂ = 3(2) - 4 = 6 - 4 = 2

a₃ = 3(3) - 4 = 9 - 4 = 5

a₄ = 3(4) - 4 = 12 - 4 = 8

The first 4 terms are

- 1, 2, 5, 8

Substitute n = 10

a₁₀ = 3(10) - 4 = 30 - 4 = 26

Answer:

Below.

Step-by-step explanation:

We get the first 4 terms by plugging in n = 1 2 3 and 4:

3(1) - 4 = -1 , 3(2) - 4 = 2 ...

First 4 terms are

-1, 2, 5, 8

10th term =   3(10) -4 = 26.

Write an equation that can be solved for p to find the number of cookies Jamie baked? A) 24/p = 56 B) p - 24 = 56 C) p + 24 = 56 B) 24p = 56

Answers

Answer:

C) p + 24 = 56

Step-by-step explanation:

The total number of cookies baked = Number of cookies Ellie baked + Number of cookies Jamie baked

Ellie baked 24 chocolate chip cookies.

Jamie baked p peanut butter cookies.

Total of 56 cookies.

Hence:

56 = p + 24

Therefore, the equation that can be solved for p to find the number of cookies Jamie baked is

p + 24 = 56

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation, and translation.

Translation is the movement of a figure up, down, left or right.

Dilation is the enlargement or reduction in the size of a figure by a factor.

Reflection is the flipping of a figure about a point.

Rotation is the turning of an image about a fixed point.  

From the image attached, triangle A was dilated (reduced) to produce triangle B.
