A scientist is measuring the temperature change in a decimal compound. The temperature dropped 11 f per hour from the original temperature. After four hours the temperature was 90 f find the compounds original temperature.

Answer:

Step-by-step explanation:

The given equation is

[tex](x-0.5)^{2} +(y-3.5)^{2} =16[/tex]

This equation belongs to a circle, which center is at (0.5, 3.5) and its radius is 4.

You can deduct its elements, becase this equation of the circle is explicit, which means the constant term represents the square power of the radius. Solving that, we have

[tex]r^{2} = 16\\r=\sqrt{16}\\ r=4[/tex]

Therefore, the radius is 4 units long.

Answer:

433

Step-by-step explanation:

Break apart into 3 hundreds, 1 ten, and 2 ones.

745 - 300 = 445

445 - 10 = 435

435 - 2 = 433

Answer:

x = 3

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

First, subtract 4 from both sides:

3x + 4 (-4) = 13 (-4)

3x = 13 - 4

3x = 9

Next, divide 3 from both sides:

(3x)/3 = (9)/3

x = 9/3

x = 3

3 is your answer for x.

Answer:

Answer:

Variable B is the area of triangular base.

B = 38.5 [tex]in^{2}[/tex].

Variable h is the height of pyramid.

In the given prism, h is 9 inches.

The volume of prism is 346.5 [tex]in^{3}[/tex].

Step-by-step explanation:

Please refer to the attached image for the detailed labeling of all the sides.

[tex]\triangle ABC[/tex] is the triangular base of the prism.

BC is the base of triangular base of the prism.

AP is the height of triangular base.

Area of triangular base is represented by B and is calculated by following formula of area of a triangle.

[tex]Area = \dfrac{1}{2} \times \text{Base}\times \text{Height}[/tex]

[tex]\Rightarrow \dfrac{1}{2} \times 11 \times 7\\\Rightarrow 38.5\ in^{2}[/tex]

Hence, B = 38.5 [tex]in^{2}[/tex].

Height of prism, h = 9 in

h is represented as side BE in the attached image.

It is know that volume of prism is given as :

V = Bh

Putting values of B and h:

[tex]V = 38.5 \times 9\\\Rightarrow V = 346.5\ in^{3}[/tex]

Answer:

The formula for volume of a prism is V = Bh.

The variable B stands for the ✔ area of the base.

In this prism, B equals ✔ 38.5  in.².

The variable h stands for ✔ height.

In this prism, h is ✔ 9 in.

The volume of the prism is ✔ 346.5  in.³.

Answer:

Area of sector: 48π in^2; Option D

Step-by-step explanation:

~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~

Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.

1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π

2. Let us see this as a proportionality:

Degree of sector/ Degree of circle = Area of sector/ Area of circle

3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:

120 / 360 = x / 144π,

120 * 144π = 360 * x,

17,280π = 360 * x,

x = 17,280π / 360,

Area of sector: 48π in^2

Answer:

The measure of [tex]MN[/tex] :

[tex]MN = 8[/tex]

Step-by-step explanation:

To find the measure of [tex]MN[/tex], add the measure of [tex]RO[/tex] and [tex]ES[/tex] together and divide it by 2 to get the actual measure of [tex]MN[/tex]:

[tex]RO =[/tex] 10

[tex]ES =[/tex] 6

[tex]MN =[/tex] unknown

-Finding the measure of [tex]MN[/tex]:

[tex]10 + 6 = \frac{16}{2} = 8[/tex]

[tex]MN = 8[/tex]

So, the measure of [tex]MN[/tex] would be [tex]8[/tex] .

Answer:

D.) x=3

Step-by-step explanation:

its right

The function will form a vertical asymptote at [tex]x=3[/tex].

Option D: [tex]x=3[/tex] is correct.

Given:

The function is [tex]f (x) = \dfrac{ 6} { x - 3 }[/tex].

We need to find the vertical asymptote of the function.

The given function is a rational function in which the denominator is [tex]x-3[/tex].

Now, the denominator should not be equal to zero.

As the function approaches [tex]x=3[/tex], the function will lead to infinity (positive or negative).

So, the function will form a vertical asymptote at [tex]x=3[/tex].

Option D: [tex]x=3[/tex] is correct.

y=|x+2|+1

Step-by-step explanation:

the equation for absolute value is y=a|b(x-h)|+k, however, in this case the equation is just y=|x-h|+k

the x value is shifted left 2 so it's |x+2|

the y value is shifted 1 up so it's +1

the equation for the graph is y=|x+2|+1
