Answer:
f(8) = 195
Step-by-step explanation:
When the x if f(x) is replaced with an 8, this just means that it is the eighth term. All you really have to do is replace every X in the function to find the answer.
f(8) = 3 + 3(8)²
f(8) = 3 + 3(64)
f(8) = 3 + 192
f(8) = 195
Hope this helps!
Answer:
195
Step-by-step explanation:
plug 8 =x into the equation

A triangle has two sides of length 13 and 8. What compound inequality describes
the possible lengths for the third side, x?
Write a compound inequality like 1
Answer:
5 < x < 21
Step-by-step explanation:
The shortest would be if the 8 leg folded back on the 13 leg
13 - 8 > 5
The logest would be if the 8 leg extended the 13 leg
13 + 8 < 21
Therefor
5 < x < 21
Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.
(-7,-2); y= - 2x+5
Write an equation for the line in slope-intercept form.
(Simplify your answer. Use integers or fractions for any numbers in the equation.)
Answer:
y = -2x - 16
Step-by-step explanation:
y = -2x + b
-2 = -2(-7) + b
-2 = 14 + b
b = -16
the function g(x)=x^2+3. the function f (x)= g (x+2).
Answer:

Find the volume of a right circular cone that has a height of 5.2 m and a base with a
radius of 15. 3 m. Round your answer to the nearest tenth of a cubie meter.
Answer:
1274.7 cubic meters
Step-by-step explanation:
Because the equation to find volume of a cone is V = πr²(h/3), you would have to plug in your values which are h = 5.2m, and r = 15.3m. Once you do the math you will get 1274.72 cubic meters, or 1274.7 when rounded to the nearest tenth.
How much Zn and how much HCl should be used to produce 1.5 g ZnCl2
Answer:
0.71963 g of Zn0.80256 g of HClStep-by-step explanation:
The required mass of reactants can be computed from the number of moles of product.
moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles
Then the mass of Zn required is ...
mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g
Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...
mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g
_____
Comment
The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.

Answer:
I believe, by process of elimination, it is "Kara's fee for the second child is $5"
Step-by-step explanation:
It can't be the second option because if her hourly rate for 2 kids was 14, then on hour 2 the total would be $28.
It can't be the third option because Jill's pattern is $11 dollars an hour, and Kara's is adding $9. So, by hour 4, Jill would make $44 and Kara would make $41.
Lastly, it can't be the 4th option because 11-9=2. 2 does not equal 3.

Answer:
57º
Step-by-step explanation:
A triangle equals 180º so to find x, just subtract the other angles from 180
180 - 39 - 84 = 57
Step-by-step explanation:
x+39+84=180 (being sum of angle of triangle is 180)
x+123=180
x=57
How do you do this and is this correct
What is 67,795 rounded to the nearest thousand?
Answer:
68 000
Step-by-step explanation:
When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.
What is the volume of a cone (in cubic inches) with a radius of 2 inches and a height of 3 inches?

Answer:
D.0
Step-by-step explanation:
If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.
Answer:
Never your answer is 0
Step-by-step explanation:
The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis

Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle.
Given and ,
° and
°.
Answer:
146°
Step-by-step explanation:
Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m arch AB=64° and ⦣ABC=73°, m ⦣ABC=__ ° and m arch AC=__ °.
Solution:
Given that:
arc AB = 64° and ⦣ABC=73°
The Central Angle Theorem states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points. The inscribed angle is any point along the outer arc AB and the two points A and B.
Therefore arc AC is the central angle of ⦣ABC. Using the central angle theorem gives:
arc AC = 2 * ⦣ABC
substituting:
arc AC = 2 * 73
arc AC = 146°
