Evaluate f(x) when x= 9

Answers

Answer 1

Answer:

The value of f(9) is equal to 498.

Step-by-step explanation:

Given that,

f(x) = 6x²+12

We need to find the value of x(9).

Put x = 9 in the given function.

f(9) = 6(9)²+12

f(9) = 498

So, the value of f(9) is equal to 498.

What is the diameter of a sphere with a volume of 72 in”, to the nearest tenth of an
inch?

Answers

The required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.

What is a sphere?

A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same distance from a single point.

The radius of the sphere is denoted by the letter r, and the specified point represents its center.

The sphere is a three-dimensional shape that is sometimes referred to as a circle's second cousin.

A sphere is a solid shape that is circular, without borders.

Balloons, toy balls, and even light bulbs are examples of objects with sphere shapes.

So, the volume of the sphere formula is:

4/3πr³

We know that the volume is 72 inches.

Then calculate as follows:

72 = 4/3πr³

r³ = 72*3/4π

r = 2.58 (Approx)

Rounding off: 2.6 inches

Then the diameter would be:
2.6 * 2 = 5.2 inches

Therefore, the required diameter of the sphere where the volume is 72 inches is 5.2 inches respectively.

A cylinder and a cone have the same volume. The cylinder has a radius of 8 inches and a height of 6 inches. The cone has a radius of 12 inches. What is the height of the cone?

Answers

Answer: [tex]8\ in.[/tex]

Step-by-step explanation:

Given

Radius and height of cylinder is 8 and 6 inches

Similarly the radius of cone is 12 inches

If they have same volume

Equate the volume of cylinder and cone

[tex]\Rightarrow \pi r^2h=\dfrac{1}{3}\pi r'^2h'\\\\\Rightarrow \pi \cdot 8^2\times 6=\dfrac{1}{3}\pi \cdot 12^2\times h\\\\\Rightarrow h=\dfrac{64\times 18}{144}\\\\\Rightarrow h=8\ in.[/tex]

Therefore , the height of cone is 8 in.

Answer:

y = 10 when x = 9

Step-by-step explanation:

y = k/x

Where,

k = constant of proportionalty

Find k when x = 6 when y = 15

y = k/x

15 = k/6

Cross product

15 * 6 = k

Determine if triangle IJK and triangle LMN are or are not similar, and, if
they are, state how you know. (Note that figures are NOT necessarily drawn to
scale.)

Answers

Yes they are similar! Both share the same angle of 61° then 20x5 is 100 just like 17x5 is 85!!

The triangles are similar, based on the Side-Angle-Side Theorem (SAS).

What is the congruent triangle?

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

By definition, since two triangles are similar if the lengths of the corresponding sides are in proportion and their corresponding angles are congruent.

In this case, we can identify that you know two pairs of corresponding sides. Then, we can find in they are in proportion.

Set up that:

In triangle IJK  and LMN

Angle JIK = Angle MLN = 61 degree

Notice that they are in proportion.

LN /  ML= IK /JI

100 / 20 = 85/ 17 = 5

we can also identify that the corresponding angles L and I are congruent because they have equal measure.

Therefore, since we know that two sides are proportionate and the included angles are congruent, we can conclude that the triangles are similar, based on the Side-Angle-Side Theorem (SAS).

supplements come in 5 kg packages
that cost $80 each. What will Doug's
order cost?

Answers

Answer:

$2000

Step-by-step explanation:

1,000 g would be = 1 Kg so it would be 25 Kg

And 25 X 80 = 2000

Answer:

$400

Step-by-step explanation:

25,000 grams is equal to 25 kg, so if 5 kg equals $80, the total 25 kg divided by 5 equals five. With this you multiply; 5 × 80 kg = 400. So $400 is the answer.

Find the coordinates of point P along the directed line segment AB so that AP to PB is the given ratio A (4,- 2),B(9, 8); 2 to 3

Answers

Answer:

(7, 4)

Step-by-step explanation:

Using the formula for calculating the midpoint expressed as;

M(X,Y) = {(ax1+bx2)/a+b, ay1+by2/a+b}

X = (ax1+bx2)/a+b

Y = ay1+by2/a+b

Substitute the given coordinate

X = 2(4)+3(9)/2+3

X = 8 + 27/5

X = 35/5

X = 7

Y = 2(-2)+3(8)/2+3

Y = -4+24/5

Y = 20/5

Y = 4

Hence the required coordinates will be at (7, 4)

[tex]\lim_{x \to \(-1} f(x)=-2[/tex]

Step-by-step explanation:

In order for a limit to exist in a piecewise function, both its right-side and left-side limits must be equal to each other:

So, if we plug in x=-1 for the left side limit, we get 2cos(πx) = 2cos(π(-1)) = 2cos(-π) = 2(-1) = -2Plugging in x=-1 for the right-side limit, we get 2/cos(πx) = 2/cos(π(-1)) = 2/cos(-π) = 2/(-1) = -2Since both the right-side and left-side limits are equal to each other, we can say that the limit of f(x) as x approaches -1 is -2, therefore the limit existsSee the attached graph

Colleen is knitting a scarf. For every 45 pieces of blue yarn she uses, she uses 18 pieces of red yard. What equation can be used to represent the proportional relationship between the amount of blue yarn, b, and red yard, r, that Colleen uses when knitting a scarf?

Answers

Given:

For every 45 pieces of blue yarn, Colleen uses 18 pieces of red yard.

To find:

The equation that can be used to represent the proportional relationship between the amount of blue yarn, b, and red yard, r, that Colleen uses when knitting a scarf.

Solution:

We have,

Blue yarn = 45 pieces

Red yarn = 18 pieces

It is given that there is a proportional relationship between the amount of blue yarn, b, and red yard, r, that Colleen uses when knitting a scarf. So,

[tex]\dfrac{r}{b}=\dfrac{18}{45}[/tex]

[tex]\dfrac{r}{b}=\dfrac{2}{5}[/tex]

[tex]r=\dfrac{2}{5}b[/tex]

Therefore, the required equation is [tex]r=\dfrac{2}{5}b[/tex].
