Answer:
Step-by-step explanation:
f(9)=5(9-3)(9-2)
=5*6*7
=210
Answer:
f(9) = 210
Step-by-step explanation:
In f(x) = 5(x-3)(x-2), replace each instance of x with 9:
f(9) = 5(9-3)(9-2), or:
=5(6)(7) = 210

Find the volume of the sphere. Round your answer to the nearest tenth. Radius is 12ft
Answer: 7238.2[tex]ft^3[/tex]
Step-by-step explanation:
The formula for a sphere's volume is [tex]V=\frac{4}{3} \pi r^3[/tex].
Substitute r = 12 in the formula: [tex]V=\frac{4}{3} \pi (12)^3[/tex]
Then calculate (type the right side of the equation above in your calculator), and you will get an answer of 2304π. When you simplify further, you get 7238.22947. Rounded to the nearest tenth, it is 7238.2.
∴, the volume of the sphere is 7238.2[tex]ft^3[/tex], to the nearest tenth.
*note: it's [tex]ft^3[/tex] (feet cubed) because a sphere is a 3D object, so its volume is also a 3D measurement.
Which of the following is NOT a terminating decimal?
A. 4.4
B. 4.44
C. 4.0444
D.
Answer:
C
Step-by-step explanation:
The others are repeated
Answer:
[tex]\text{D. }44.\overline{4}[/tex]
Step-by-step explanation:
*The person who asked this question clarified answer choice D should be [tex]\text{D. }44.\overline{4}[/tex].
Define a terminating decimal by a decimal that has a finite (or fixed) number of digits. Answer choices A, B, and C all have a finite number of digits, thus they are terminating decimals. The overline is answer choice D is using to represent that digit (4) is repeating and therefore there are an infinite number of digits in the decimal. Thus, [tex]\boxed{\text{D. }44.\overline{4}}[/tex] is not a terminating decimal.

Hellopoooopppoo
Quickkkkkkkkkkkkkkk
Answer:
4.5 units
Step-by-step explanation:
PQ transferred to WX, and QR to XY.
PQ = 4, WX = 6, so the scaling factor x applies so that we create 6 or of 4 :
4 × x = 6
x = 6/4 = 3/2
the save scaling factor applies now to all other sides too due to the fact that the same transformation was done to the whole shape.
=> QR × 3/2 = XY.
3 × 3/2 = 9/2 = 4.5 = XY

A sequence has three terms.
Its term-to-term rule is
multiply by 6 and then add 13
a) The first term of the sequence is -2
Work out the third term.
b) The order of the three terms of the sequence is reversed.
Describe the term-to-term rule of the new sequence.

It's C
Step-by-step explanation: I took the test and got it wrong
The third term of the given sequence exists 19.
Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex] is reversed will be [tex]$\frac{a-13}{6}$[/tex].
What is a sequence?The sequence exists in a particular order in which connected things follow each other.
The term-to-term rule of the sequence stands 6a+13, where a stands for the first term First-term a = -2
Second term b will be [tex]$-2*6+13=1$[/tex]
The rule for the third term will be 6b+13, where b will be the second term. So the third term will be [tex]$6* 1+13=19$[/tex]
So, the sequence will be [tex]$-2,1,19 \ldots \ldots . .$[/tex]
If the order of the above sequence stands reversed, the new sequence will be [tex]$19,1,-2 \ldots \ldots .$[/tex]
If we subtract 13 from first term 19 and then divide by 6 we will get 1 which stands for the second term of the new sequence [tex]$19,1,-2 \ldots \ldots .$[/tex]
So a new term-to-term sequence rule will be [tex]$\frac{a-13}{6}$[/tex] where a stands for the first term.
Therefore, the third term of the given sequence exists 19.
Term to term rule when the sequence [tex]$-2,1,19 \ldots .$[/tex] exists reversed will be [tex]$\frac{a-13}{6}$[/tex].

Pablo drove 715 miles in 11 hours.
At the same rate, how many miles would he drive in 9 hours?
Answer:
585 miles
Step-by-step explanation:
divide 715 by 11 so that you can see the mph (miles per hour). Then multiply that number by 9 for the amount of miles he would travel in nine hours
715/11=65
65x9=585

Write in standard form the equation of a line with a slope of -3/5 and a y intercept of -3
Answer:
5y+3x=-9
Step-by-step explanation:
Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the slope-intercept form of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.
From this problem, we are given both the slope and the y intercept. We know have the equation:
[tex]y=-\frac{3}{5}x -3[/tex]
Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.
[tex]y+\frac{3}{5} x=-3[/tex]
This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.
[tex]5y+3x=-9[/tex]
I hope this helps! Please let me know if you have any questions :)
A closed container has 2.04 ⋅ 1023 atoms of a gas. Each atom of the gas weighs 1.67 ⋅ 10−24 grams. Which of the following shows and explains the approximate total mass, in grams, of all the atoms of the gas in the container?
0.34 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068 ⋅ 10−1
0.37 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71 ⋅ 10−1
3.41 grams, because (2.04 ⋅ 1.67) ⋅ (1023 ⋅ 10−24) = 3.4068
3.71 grams, because (2.04 + 1.67) ⋅ (1023 ⋅ 10−24) = 3.71
Answer: 0.34 grams
Step-by-step explanation:
Given:
Number of atoms in a closed container
Weight of one atom
Total mass of all the atoms of the gas in the container
Thus A is the right option.
Answer:
0.34 grams

find the value of x.
Answer:
139 degrees
Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees
The diagram shows a sector OAPB of a circle, centre O.
AB is a chord of the circle.
OA = OB = 5.4 cm.
Angle AOB = 72°
Calculate the area of the shaded segment APB.
Give your answer correct to 3 significant figures.
Answer:
4.44 cm²
Step-by-step explanation:
If the diagram attached below is required to complete the question,
Applying,
Area of the shaded segment(A) = Area of the sector- area of the triangle
A = (πr²∅/360)-(r²sin∅/)2................ Equation 1
Where r = radius of the circle, ∅ = angle at the center of the circle,π = pie
From the question,
Given: r = 5.4 cm, ∅ = 72°
Constant: π = 3.14
Substitute these values into equation 1
A = (3.14×5.4²×72/360)-(5.4²/2×sin72)
A = 18.31-13.87
A = 4.44 cm²
What is the value for X?
Answer:
5
Step-by-step explanation:
6x + 4 + 73 + 73 = 180
6x + 150 = 180
6x = 30
x = 5
Those little marks on AB and BC denote congruence. That makes the triangle isoceles. That means the base angles are equal. Both 73.
Triangle Sum Theory states all angles of a triangle add to 180.

Here is a picture of three towers.
Not all the cubes can be seen in the towers.
Edith uses 1 cube to build tower 1.
Edith uses 6 cubes to build tower 2. There are 5 cubes on the bottom layer.
The sequence below shows the number of cubes used for the bottom layer of each tower.
Answer:
nth term = the previous number times 4(x-1)
Step-by-step explanation:
As you see the first tower has 1 then it is 5 for the next tower and then it is 13 for the next tower and then 25. Well this means that as you see, the expressions adds 4 to the previous 4 and then adds to the tower. Let me show you how it works.
Tower 1: 1
Tower 2: 1 + 4 = 5
tower 3 : 5 + 8 = 13
tower 4: 13 + 12 = 25
tower 5: 25 +16 = 41

Find the surface area
Answer:
352 m
Step-by-step explanation:
The area of a trapeze is (the biggest base + the smallest base) × height / 2
The area from rectangles are side a × side b
Trapeze: (6+12)×4/2 = 36
Rectangles: 5 × 10 = 50
6 × 10 = 60
12 × 10 = 120
There are two trapeze andtwo rectangles with the samesize, so you double their area:
2×36 + 2 × 50 + 60 + 120 = 352 m
