Find zeros and y intercept of each function algebraically f(x)=x^3-10x^2+24x
Answer:
The zeros are 0, 4, 6.
The y-intercept is 0.
Step-by-step explanation:
f(x) = x^3 - 10x^2 + 24x
x^3 - 10x^2 + 24x = 0
x(x^2 - 10x + 24) = 0
x(x - 4)(x - 6) = 0
x = 0 or x - 4 = 0 or x - 6 = 0
x = 0 or x = 4 or x = 6
y-intercept:
Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.
You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).
Let x = 0.
f(0) = 0^3 - 10(0^2) + 24(0)
f(0) = 0
y-intercept: 0

Why might algebra tiles not be a good tool to use to factor x2 + 18x + 80? Explain.
Step-by-step explanation:
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.
There are a lot of tiles to drag onto the board.
You would need to create a rectangle from 99 tiles.
80 is a multiple of 10, so it has factors of 10 and 8, which add to 18.

Basil has five numbered cards.
Two of the numbers are hidden. 4 9 9 ? ? 8
The mode of the five numbers is 8.
The mean of the five numbers is 6
c) Work out the two hidden numbers.
Answer:
The two hidden numbers are 8 and 1.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is given by the sum of all its values divided by the number of values.
Mode of a data-set:
The mode of a data-set is the value that appears the most.
In this question:
4, 9, x, y, 8
Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:
4, 9, 8, y, 8
The mean of the five numbers is 6
This means that:
[tex]\frac{4+9+8+y+8}{5} = 6[/tex]
[tex]29+y = 30[/tex]
[tex]y = 30 - 29[/tex]
[tex]y = 1[/tex]
The two hidden numbers are 8 and 1.

A different camera is selling for $7.50 off the regular price. It was discounted 15%. What was the original price of the camera?
A)$112.50
B)$75.00
C)$50.00
D)$45.00
Answer:
C) $50.00
Step-by-step explanation:
$7.50 is the 15% discount
1% of the original price would be ($7.50 / 15)=0.50
100% of the original price would be 100 x 0.50 = $50.00
Renee and Thomas live at the beach and collect seashells. The number of shells Renee collects on any given day, R, is approximately Normal with a mean of 58.2 shells and a standard deviation of 12.8 shells. The number of shells Thomas collects on any given day, T, is approximately Normal with a mean of 47.9 shells and a standard deviation of 11.5 shells. Assume the two random variables are independent of each other. What is the probability that on a randomly selected day the total number of shells collected by Renee and Thomas is 120 or more? 0.002 0.209 0.284 0.791

sin0=? cos0=? tan1=?
Answer:
See explanations below
Step-by-step explanation:
Sin 0 = x
0 = arcsinx
Since 0 the angle is positive and lies in the 1st and second quadrant, sin 0 = 0 (in the first quadrant)
cos 0 = 1 (by punching the calculator)
tan 1 = 0.0174
All this values can easily be gotten directly from calculators

Jason has 1/3 of a liter of milk. Jason divides the milk equally into 4 mugs of tea.
How much milk will Jason have in each mug?
Answer:
1/12 l
Step-by-step explanation:
Amount of milk = 1/ 3 l
No: of mugs = 4
Amount in each mug = 1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l
(Hope its right!)
Answer:
They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4

[tex]m= 14 \sqrt 2, \: n = 14[/tex]
Step-by-step explanation:
Hope it helps you in your learning process.
Given is a 45°-45°-90° triangle.
Measure of sides n and 14 are opposite to 45° degree angles.
Therefore, they are equal.
So, n = 14
[tex] 14 = \frac{1}{\sqrt 2}\times m[/tex]
[tex] 14 \sqrt 2=m[/tex]

14=s/3 what does s equal
===============================================
Explanation:
To isolate s, we need to undo the division. We'll multiply both sides by 3
14 = s/3
3*14 = 3*(s/3)
42 = s
s = 42
-------
As a check,
14 = s/3
14 = 42/3 .... replace s with 42
14 = 14
We get the same thing on both sides, so this confirms we have the correct value of s.
work out the size angle DEF
Answer:
Step-by-step explanation:
Here, we want to get the value of angle DEF
we have this as ;
Angle DEF = 1/2 * DOF
1/2 * 150 = 75
This is because angle at the center is twice the angle at the circumference

Solve two fifths minus one seventh equals blank.
Answer:
9/35.............,..........
Answer:
1/5
Step-by-step explanation:
2/5 - 1/7 = ???
find the least common denominator!
45 would be the least common demoninator!
so...
2 (7) / 5(7) - 1 (5) / 7 (5) = ?
14/ 45 - 5 /45 = ?
14 - 5 = 9
9/45. Simplify!
9/45 divide 9 from both sides
9/9 / 45/9
= 1/5, one fifths is your answer!
