If f(x) = x²-5x and g(x) = 2x-3, which expression represents the product of these two functions?1) x²-3x-3
2) 2x³-13x²+15x
3) 9x²-15x
4) 2x³-15x

Answers

Answer 1
Answer: 2).  (x² - 5x) (2x - 3) = 2x³ -13x² + 15x
Answer 2
Answer: product=f(x)\cdot g(x)=(x^2-5x)(2x-3)=2x^3-3x^2-10x^2+15x=\n\n=2x^3-13x^2+15x\ \ \ \Rightarrow\ \ \ Ans.\ 2)

The art room at a school is made up of three​ sections: a pottery​ section, a painting​ section, and a sculpture section. Complete questions 6–7 below. LOADING... Click the icon to view the diagram of the art room. 6. Artwork will be on display for an art show in all sections of the art room except the sculpture section. How much space is available for the art​ show?

Answers

Answer:

Step-by-step explanation:

huh huh huh huh whatttttttttttttt

Final answer:

The space available for the art show in the school's art room is the sum of the space allocated for the pottery section and the painting section. Exact values can't be provided without more information or diagrams.

Explanation:

To determine the amount of space available for the art show in the school's art room, we need to add together the space allocated for the pottery section and the painting section. Unfortunately, without more information or diagrams indicating the exact dimensions or square footage of these areas, we cannot provide a numerical answer. However, remember that when you have the information, you simply add the space of the pottery section to the space of the painting section to get the total art show space.

To calculate the volume of a cylinder, we have equation like this: V = πd 2 4 h = πr 2h d is the diameter, r is the radius and h is its height. We can measure the diameter (r = d 2 ) and height directly. To calculate the confidence interval of the volume, we should use the propagation of errors. We use the micrometer screw to measure the diameter. The minimum interval on the screw is 0.01mm. What is the confidence interval for δd and δr?

Answers

Answer:

\delta d = +/- 0.01 mm

\delta r = +/- 0.02 mm

Step-by-step explanation:

\delta d. The error of a quantity directly measured is the uncertainty of the tool used for measuring. So error for diameter is 0.01 mm.

\delta r. The error of a quantity obtained multiplying/dividing a measure by a constant is calculated multiplying/dividing the measure uncertainity by the same constant. Radius is calculated as r=2*d, so we calculate \delta r  multiplying the diameter uncertainty by 2 (\delta r = 2*0.01=0.02).

Cut the sign in half across its middle.  Then you have two right triangles.
They're congruent, so pick one to work with, and discard the other one
temporarily.

In the right triangle:

-- The length of one leg is 'x'.
-- The length of the other leg is (2x + 7).
-- The length of the hypotenuse is  35.47 inches.

You know that in any right triangle:

(The square of the hypotenuse) =
                     (the square of one leg) + (the square of the other one.)

so you can use that to find the value of 'x'.

One you know the value of 'x', go back to the whole sign before you cut it
in half, and notice that the height of the sign is '2x' ... which is the answer.
height =2x so we must find x then multiply by 2

if we cut the triangle in half from with the line from left to right, we have a trianlgle that is x high and 2x+7 wide and the hyposonuse that is 35.47 so
a^2+b^2=c^2
x^2+(2x+7)^2=35.47^2
x^2+4x^2+28x+49=1258.12
group like terms
5x^2+28x+49=1258.12
subtract 1258.12 from both sides
5x^2+28x-1209.12=0
factor 5(x-13.0008)(x+18.6008)=0
therefore
(x-13.0008) or/and (x+18.6008)=0
x-13.0008=0
add 13.0008 to both sides
x=13.0008

x+18.6008=0
subtract 18.6008 from both sides
x=-18.6008
since heights cannot be negative, this solution can be discarded

so x=13.0008
2x=height=26.0016

Solve for f please. c=5/9 (f-32) show work thank u (:

Answers

               C = 5/9(F - 32)

Multiply each side by  9/5 :      9/5 C = F - 32

Add 32 to each side:                9/5 C + 32  =  F
c=5/9 (f-32)
c = 5/9f-160/9 /*9
9c=5f-160
5f-160=9c
5f=9c+160 /: 5
f = (9c+160)/5
