Answer:

54.8 (rounded to the nearest tenth from 54.76558202)

Step-by-step explanation:

Using the Cosine equation (CAH) you type in a calculator "cos(x) = 4.5/7.8".

This will get you the answer if typed in a calculator and hitting "SOLVE".

Answer:

It is not a function

Step-by-step explanation:

In function, each x-value has only one y-value

Here the x-value of 7 has two y-values of -3 and -1

Answer:

x = 14

<CAD = 42degrees

Step-by-step explanation:

Since all the rays meet at a point, the sum of all the angles at the point will be 360 degrees, since angle at a point is 360degrees

Taking the sum of all the angles and equating to 360, we will have;

<BAC + <DAE + <BAE + <CAD = 360

60+90+12x+3x = 360

150 + 15x = 360

15x = 360 - 150

15x = 210

x = 210//15

x = 14

Get <CAD

Since <CAD = 3x

<CAD = 3(14)

<CAD = 42 degrees

Hence the measure of angle CAD is 42degrees

Answer:

a=2

b=40m

c=2m/s

Step-by-step explanation:

slope is rise over run so 10/5 simplified is 2/1 or 2

for b just look at the graph at the 20th second

for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

D. x⁶ + 4x³ + 10x⁷

Answer:

[tex] { - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

Step-by-step explanation:

For a polynomial to be in standard form, it must satify the conditions below:

1) It must not contain like terms

2) The exponents (powers) must be written in descending order

That is, the polynomial must be of the form

[tex]f(x) = {ax}^{n} + {bx}^{n - 1} + {cx}^{n - 2} + . \: . \: . \: . \: . \: mx + n[/tex]

Where a, b, c, m, n, are coefficients/constants

The only option that satifies the above conditions, and follows the pattern f(x) shown is:

[tex]{ - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

Answer: SAS

Step-by-step explanation: The angles sides are congruent based on the diagram

Answer:

48

Step-by-step explanation:

Since it's a right angle, it's automadically 90 degrees so you just have to add 23+ 19 and subtract from 90.

23 + 19 = 42

90 - 42 = 48

Answer:

c = 18

d = 36

Step-by-step explanation:

2c = d (equation 1)

c + d = 54 (equation 2)

Use substitution by putting 2c in the place of d on the second equation.

c + 2c = 54

3c = 54

Then divide both sides by 3 to get c (18).

Then use equation 1 to find d. Do this by putting 18 in the place of c.

2(18) = d

Solve, and the answer is d = 36

Answer:

(3 x)/(5 x + 2)

Step-by-step explanation:

Simplify the following:

(3 x^2)/(5 x^2 + 2 x)

Hint: | Factor common terms out of 5 x^2 + 2 x.

Factor x out of 5 x^2 + 2 x:

(3 x^2)/(x (5 x + 2))

Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (3 x^2)/(x (5 x + 2)).

Combine powers. (3 x^2)/(x (5 x + 2)) = (3 x^(2 - 1))/(5 x + 2):

(3 x^(2 - 1))/(5 x + 2)

Hint: | Evaluate 2 - 1.

2 - 1 = 1:

Answer:  (3 x)/(5 x + 2)
