x^2– 7x- 18
(Factor the following))
Answer:
(x - 9)(x + 2)
x = 9 or -2
Step-by-step explanation:
First, we need to find factors of 18 that add up to -7
Factors of 18:
1 and 18
2 and 9
3 and 6
Add/Subtract them to have a total sum of -7
18 - 1 = 17 ...... 1 - 18 = -17 (not -7)
9 - 2 = 7 ........ 2 - 9 = -7 (sum of -7)
6 - 3 = 3 ......... 3 - 6 = -3 . (not -7)
Hence the numbers that would go in the brackets would be -9 and 2
(x - 9)(x + 2)
x² - 7x - 18
Answer:
(x-9)(x+2)
Step-by-step explanation:
The first term is the product of two x's being multiplied together. the second term (-7x) is the sum of the two numbers. -18 (the third term) is the product of those numbers.
Think: what two numbers will add up to -7 and multiply to -18
Those numbers are -9 and 2
Now, this is a quadratic trinomial, and you factor these kinds of equations like this: (x+a)(x+b) (a and b as placeholders for actual numbers)
Now, plug -9 and 2 in
(x-9)(x+2)

You are working as a cashier. You start with $500 in your cash register and the money in the cash register increases by $1000 each hour. Given: f(x) = 1000x +500 Part A Solve for x when f(x) = 2000 Part B What does the solution mean in context?
Answer:
The answer is below
Step-by-step explanation:
A linear function is given as y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change and b is the initial value of y (that is when x = 0).
Let x represent the number of hours and f(x) the amount of money in the cash register. Given that the cash register increases by $1000 each hour and the initial value of money in the cash register is $500. hence:
f(x) = 1000x + 500
a) At f(x) = 2000
2000 = 1000x + 500
1000x = 1500
x = 1500/1000
x = 1.5 hours
b) This means that after 1.5 hours, the amount of money in the cash register is $2000

Write an equation of the parabola in vertex form.
Answer:
[tex]y= -\frac19(x-3)^2+1[/tex]
Step-by-step explanation:
the x-3 is to shift a normal parabola 3 to the right
the +1 is to lift the top up by one
the -1/9 is to compress and swapt it around
Answer:
y =- [tex]\frac{1}{9}[/tex](x - 3)² + 1
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1) , thus
y = a(x - 3)² + 1
To find a substitute another point on the graph into the equation
Substitute (1, [tex]\frac{5}{9}[/tex] ) into the equation
[tex]\frac{5}{9}[/tex] = a(1 - 3)² + 1 ( subtract 1 from both sides )
- [tex]\frac{4}{9}[/tex] = 4a ( divide both sides by 4 )
a = - [tex]\frac{1}{9}[/tex]
y = - [tex]\frac{1}{9}[/tex] (x - 3)² + 1 ← equation of parabola in vertex form

Julius sprinted 68 meters. Reece sprinted diagonally across a diagonal field that measures 16 meters by 63 meters. Who sprinted a longer distance, and by how many meters?
Answer:
Step-by-step explanation:
The answer will surprise you. My guess, before doing it, is Reece went further than Julius.
Reece
distance = sqrt(16^2 + 63^2)
distance = sqrt(256 + 3969)
distance = sqrt(4225)
distance = 65
Looks like I have to eat humble pie. The answer is that Julius went 3 meters further than Reece.

Ice has a density of 0.92 gram per cubic centimeter. What is the total volume of a block of ice that has a mass of 2.3 kilograms?
Answer:
2500 cubic centi meters or 2.5 liters or 0.0025 cubic meters
Step-by-step explanation:
[tex]p = m \v[/tex]
So v=m/p
Before puting numbers in formula
Change kilogram to gram
Or change gram per cubic centimeter to kilogram per cubic meters
At last you'll reach the number 2500 cubic centimeters or 0.0025 cubic meters.
The total volume of a block of ice that has a mass of 2.3 kilograms is 0.0025 cubic meter.
What is a cube?A cube is a three-dimensional representation of a square. it has 6 faces 2 on the bottom and top, 4 on the sides faces.
The volume of a cube can be calculated as the cube of the sides of a given figure.
The volume of a cube =a^3
We are given that;
Density= 0.92 gram per cubic centimeter.
Now,
We need to convert the units to be consistent, so we can either convert kilograms to grams or cubic centimeters to cubic meters. Let’s do the latter:
1 cubic meter=100×100×100 cubic centimeters=106 cubic centimeters
0.92 gram per cubic centimeter=0.92×106 gram per cubic meter=920000 gram per cubic meter
Now we can substitute the values into the formula and find the volume:
V=ρm
V=920000 gram per cubic meter2.3 kilograms
We need to convert kilograms to grams as well:
1 kilogram=1000 grams
Therefore,
V=920000 gram per cubic meter2.3×1000 grams
V=9200002300 cubic meter
Simplifying, we get:
V=0.0025 cubic meter
Therefore, by the volume of cube the answer will be 0.0025 cubic meter.
