Answer:

233.5 in²

Step-by-step explanation:

First we have to find the slant height.

5²+14²=c²

25+196=c²

221=c²

c=14.866

Now we can find the lateral area.

Answer:

Part A : see composition process below

Part B :    [tex]Domain=\{x\,|\,x\neq 0\}[/tex]

Step-by-step explanation:

Part A

Let's use the composition of functions to find if they give the identity : [tex]f(g(x))=x[/tex]  thus proving they are the inverses of each other:

[tex]f(g(x))=f(\frac{5x+1}{x} )=\frac{1}{\frac{5x+1}{x}-5} =\frac{1}{\frac{5x+1-5x}{x}} =\frac{1}{\frac{1}{x} } =x[/tex]

So we have proved they are the inverses of each other.

Part B

Given that the composition is:

[tex]f(g(x))=\frac{1}{\frac{1}{x} }[/tex]

the Domain must exclude x=0, for which this quotient is undefined.

The Domain is then:

[tex]Domain=\{x\,|\,x\neq 0\}[/tex]

Answer:

They should refinish 96 tables using method 1

They should refinish 82 tables using method 2

Step-by-step explanation:

Let

a = number of tables refinished using method 1

b = number of tables refinished using method 2

Time equation

a+2b=260 (1)

Cost equation

6a+5b=986 (2)

a+2b=260 (1)

6a+5b=986 (2)

Multiply (1) by 5 and (2) by 2

5a+10b=1,300 (3)

12a+10b=1,972 (4)

Subtract (3) from (4)

7a=672

Divide both sides by 7

a=96

Recall,

a+2b=260

96+2b=260

2b=260-96

2b=164

Divide both sides by 2

b=164/2

=82

They should refinish 96 tables using method 1

They should refinish 82 tables using method 2

Answer:

80

Step-by-step explanation:

0,   3,   8,   15,   24,  35,   48,   63,  80 which is the nth term

first step you have to find how many steps the sequence was going with.

examples= from 0 to 3 the steps were 3

                =from 3 to 8 the steps were 5

                = from 8 to 15 the steps were 7

you will recognize that the steps the sequence is going with is odd numbers.

so you will use the odd numbers until you find what you need. which leads you to 80 which is the nth number in the sequence.

Answer:

80

Answer:

A. -8

Step-by-step explanation:

[tex]x^2-10x+8=0[/tex]

then we subtract 8 from both sides

[tex]x^2-10x+8-8=0-8[/tex]

[tex]x^2-10x=-8[/tex]

The value on the right side is -8 in the process of completing the square.

Answer:

x = 148

Step-by-step explanation:

CPD is a straight line so it equals 180

CPB + BCD = CPD

x + 32 = 180

Subtract 32 from each side

x+32-32 = 180-32

x =148

Answer:

x = -2

Step-by-step explanation:

If you have any questions about the way I solved it, don't hesitate to ask ;)

The value of the function (f+ g)(x) = 0 then x = -2.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Given:

f(x) = x² - 2x and g(x) = 6x + 4

As,  (f+g)(x) = 0

x² - 2x + 6x + 4 = 0

x² + 4x + 4 =0

x² + 2x + 2x + 4 = 0

x(x+2) + 2 (x +2 )= 0

(x + 2)(x+2) = 0

(x+ 2)²= 0

x+ 2= 0

x = -2

Answer:

[tex] 0.7287[/tex]

Step-by-step explanation:

Let $534.9=a$

Thus, given:

$\log a=2.7287$

Hence:

$\log \Big( \frac{a}{100}\Big)=\log a- \log 100$

$\implies \log \Big( \frac{a}{100}\Big)=2.7287-2=0.7287$

Answer:

c) p = 3/q

Step-by-step explanation:

If 3 is divided by a smaller number "q", then it would result in a larger number "p".

Example:

1. Substitute 3 for "q"

3/3 = 1

q = 3

p = 1

2. Substitute 1 for "q"

3/1 = 3

q = 1

p = 3

When "q" decreased, "p" increased.

Step-by-step explanation:

c) p=3/q

Answer:

A. 30 degrees

Step-by-step explanation:

Set the two angles equal to each other:

3x-15 = 45-x

Solve for x:

4x -15 = 45

4x = 60

x = 15

Finally, plug in the x to one of the equations (preferably 45 - x since it's easier to solve) and solve for x.

45 - 15 = 30

Answer:

A 30 degrees

Step-by-step explanation:

Hence, the m∠DCA is 59.2

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs, and sometimes the arms of the angle.

m∠DCB = (4x) + (6x-58) = 90

10x = 148

x = 14.8

m∠DCA = 4x

             = 4(14.8)

             = 59.2

Answer:

x=9

Step-by-step explanation:

PQ + QR + RS = PS

2x-6 + 1 + x-4 = 18

Combine like terms

3x -9 = 18

Add 9 to each side

3x-9+9= 18-9

3x = 27

Divide by 3

3x/3 = 27/3

x = 9

Answer:

RS=5

Step-by-step explanation:

solve for x:

2x-6+1+x-4 = 18

combine like terms

3x-9=18

subtract both sides to make x isolated

3x=27

divide by 3 to get x

x=9

A) 24+24+120+160+200

Step-by-step explanation:

The two ends are 24 (1/2bh= 1/2(8*6)).

One side (the back) is 6x20=120

One side (the bottom) is 8x20=160

One side (the top) is 10x20=200

So the equation is 24+24+120+160+200

Answer:

A

Step-by-step explanation:

From the graph we can notice that the coordinates of the poinrs x and y are:

● x(-2,0)

● y(3,-2)

There are many methods to find the distance between x and y. We will use the distance formula.

Let d be the distance between x and y.

● d = √[(-2-3)^2 + (0-(-2))^2]

● d = √[(-5)^2 + 2^2]

● d = √(25+ 4)

● d = √(29)

The other method was using the pythagorian theorem. d is the hypotenus.

ΔANT ≅ ΔFLE by the SIde-Side-Side (SSS) rule of congruency

Step-by-step explanation:

The given information are;

Segment TN is congruent ts segment EL

Segment TA is congruent ts segment EF

Segment AN is congruent ts segment FL

Therefore, triangle ΔANT is congruent to ΔFLE by the Side-Side-Side (SSS) rule of congruency

One of the rule used to serve as proof that two or more triangles are congruent, is the Side-Side-Side (SSS) rule of congruency. The Side-Side-Side rule of congruency states that if the dimensions of the three sides of one triangle are equal to the dimensions of the three sides of another triangle, the two triangles are congruent.

Therefore, the correct option is ΔANT ≅ ΔFLE by the Side-Side-Side (SSS) rule of congruency
