Answer:

61 degrees.

Step-by-step explanation:

Any triangle's interior angles must add up to 180. 67 + 52 = 119. 180 - 119 = 61.

Answer:

The value of x is 61 degrees

Step-by-step explanation:

Becasue a triangle can have a total degrees of 180 and if we add the degrees of B and C you get 119 and if you subtract that from 180 you get 61, therefore 61 degrees is the value of x

For the given word problem, identify the rate of change. Gasoline at a particular gas station costs $2.78 per gallon. If Cory bu
zhenek [66]

Answer:

Cory bought 6.47 gallons

rate of change is $2.78 per gallon

Step-by-step explanation:

cost of gas per gallon = $2.78

it means that if one buy 1 gallon he will have to pay $2.78 and similary for each increase in 1 gallon of gallon gas he will have to pay $2.78.

Thus, rate of change is cost of gas per gallon as cost to buy gas changes with the change in quantity of gallon.

Let the quantity of gas bought be x gallon.

Total cost for x gallons = cost of gas per gallon*x = 2.78x

Given that total money paid by him is $18

2.78x = 18

x = 18/2.78 = 6.47

Thus, Cory bought 6.47 gallons

rate of change is $2.78 per gallon

The cost to ride a ferris wheel is $2.00 per person. The ferris a wheel has a capacity of
irakobra [83]

Answer:

When we have a function f(x), the domain of the function is the set of all the inputs that "work" (Not only in a mathematical way, the context is also important) with the function f(x)

In this case, we have a function M(p) = $2*p

This function represents the amount of money collected depending on the number of people who ride on the ferris whell.

Then p can be only a whole number (we can not have 1.5 people, only whole numbers of people).

And we also know that the maximum capacity of the ferris is 64 people.

Then:

p ≤ 64

And we also should add the restriction:

0 ≤ p ≤ 64

(Because p can't be smaller than zero)

Such that p should also be an integer, then, the domain is:

D: p ∈ Z, p ∈ {0, 1, 2, ..., 64}

Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (fxg)(-5).<br><br> a. -59<br> b. 3<br> c. 26<br> d. -6
DedPeter [7]

Answer:

78

Step-by-step explanation:

The given functions are:

f(x) =  - 2x - 7

and

g(x) =  - 4x + 6

(f \times g)(x) = f(x) \times g(x)

(f \times g)(x) = ( - 2x - 7)( - 4x + 6)

When we plug in x=-5, we get:

(f \times g)( - 5) = ( - 4 \times -  5 + 6)( - 2 \times  - 5 - 7)

(f \times g)( - 5) = ( 20 + 6)( 10 - 7)

(f \times g)(5) = ( 26)( 3) =7 8
