Answer:

50/3

Step-by-step explanation:

For x

3x-2(2+1)=4

3x-2(3)=4

3x-6=4

3x=4+6

3x=10

x=10/3

as we have to find 5x=?

5(10/3)

Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three op

iVinArrow [24]

The statement that are true about the function and its graph is "The graph of the function is a parabola " , the correct option is (b) .

In the question ,

it is given that ,

the quadratic function is f(x) = x² – 5x + 12 .

for x = -10 ,

f(-10) = (-10)² – 5(-10) + 12

= 100 + 50 + 12

= 162

option(a) is false .

the graph of the quadratic function is shown below .

form the graph we can see that the graph is a parabola ,

and the function opens upwards ,

the graph does not contain the points (20,-8) and (0,0)

Therefore , The statement that are true about the function and its graph is "The graph of the function is a parabola " , the correct option is (b) .

The given question is incomplete , the complete question is

Consider the quadratic function f(x) = x² – 5x + 12. Which statement is true about the function and its graph?

(a) The value of f(–10) = 82

(b) The graph of the function is a parabola.

(d) The graph contains the point (20, –8).

(e) The graph contains the point (0, 0).

poizon [28]

Answer:

We know that:

There is a total of 81 houses:

51 had a finished basement.

56 had a three-car garage.

37 had a finished basement and a three-car garage.

a) How many had a finished basement but not a three-car garage?

51 had a finished basement, and 37 have a finished basement and the garage, then:

51 - 37 = 14 hoses have only the basement.

b) How many had a three-car garage but not a finished basement?

Same reasoning as above:

56 - 37 = 19 houses only have the garage.

c) How many had either a finished basement or a three-car garage?

Now we only count the ones that have one finished thing, in this case, we already found the number of houses that have only the garage or only the basement, then the number of houses that either had a finished basement or a finished garage is:

19 + 18 = 37 houses.

Sin 0 = 0.731353701, 0º PLEASE HELP!!

Snezhnost [94]

Answer:

The two solutions for $\sin \theta = 0.731353701$ are $\theta_{1} \approx 47^{\circ}$ and $\theta_{2}\approx 133^{\circ}$ , respectively.

Step-by-step explanation:

The sine function is positive in the first and second quadrants, that is, $0^{\circ}< \theta < 180^{\circ}$ . Then, there are two solutions for the given value by means of the following inverse trigonometrical function:

$\theta = \sin^{-1} 0.731353701$

$\theta_{1} \approx 47^{\circ}$ and $\theta_{2}\approx 133^{\circ}$

The two solutions for $\sin \theta = 0.731353701$ are $\theta_{1} \approx 47^{\circ}$ and $\theta_{2}\approx 133^{\circ}$ , respectively.
