Answer:
y^2-1=80
y^2=81
y = positive and negative 9
y2−1=80
Step 1: Add 1 to both sides.
y2−1+1=80+1
y2=81
Step 2: Take square root.
y=±√81
y=9 or y=−9
Answer:
y=9 or y=−9

139 km
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]50^{2} + 130^{2} = c^{2} \\2500 + 16900 = 19400^{2}\\[/tex]
[tex]\sqrt{19400}[/tex] = 139.28

If you but t tacos for c dollars what is the unit rate
Answer:
wdym
Step-by-step explanation:
The unit rate of t tacos for c dollars is t/c.
Given that, t tacos costs for c dollars.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Here,
The unit rate = Number of tacos/Cost of t tacos
= t/c
Therefore, the unit rate of t tacos for c dollars is t/c.

h(1)= 9
h(n)=h(n−1)⋅(-3)
Find an explicit formula for h(n).
h(n)= ?
Given:
[tex]h(1)=9[/tex]
[tex]h(n)=h(n-1)\cdot (-3)[/tex]
To find:
The explicit formula for h(n).
Solution:
We have,
[tex]h(n)=h(n-1)\cdot (-3)[/tex] ...(i)
It is the recursive formula of a geometric sequence. It is of the form
[tex]a(n)=a(n-1)\cdot r[/tex] ...(ii)
where r is the common ratio.
On comparing (i) and (ii), we get
[tex]r=-3[/tex]
We have, [tex]h(1)=9[/tex] so the first term of the geometric sequence is [tex]a=9[/tex].
The explicit formula for a geometric sequence is:
[tex]h(n)=ar^{n-1}[/tex]
Substitute a=9 and r=-3 to get the explicit formula for the given sequence.
[tex]h(n)=9(-3)^{n-1}[/tex]
Therefore, the required explicit formula is [tex]h(n)=9(-3)^{n-1}[/tex].

Answer:
1725ft^2
Step-by-step explanation:
Area of trapezoid:
[tex]\frac{b_1+b_2}{2}*h[/tex]
Substitute the values and solve:
[tex]\frac{50+65}{2}*30=1725[/tex]ft^2
Answer:
1725 sq.ft
Step-by-step explanation:
Given
Parallel sides of the trapeziod yard = 50ft , 65ft
Height of the trapezoid = 30ft
Therefore, area of the trapezoid yard
[tex] = \frac{b1 + b2}{2} \times h[/tex]
[tex] = \frac{50ft + 65ft}{2} \times 30ft[/tex]
[tex] = \frac{115ft}{2} \times 30ft[/tex]
= 57.5 ft × 30 ft
[tex] = 1725 {ft}^{2} (ans)[/tex]

Write an equation for expense (blue line)
I would really appreciate if someone helped me I'm not understanding this.
Answer: y = 0.0005x+1
This is the same as saying y = (1/2000)x + 1
===============================================================
Explanation:
The blue line goes through (0,1) and (2000,2)
The slope is
m = (y2-y1)/(x2-x1)
m = (2-1)/(2000-0)
m = 1/2000
This says that each time we move up 1, we move to the right 2000 units.
Think of it as slope = rise/run = 1/2000
The slope 1/2000 means that each time you make 2000 soccer balls, it will cost you $1000. Keep in mind that y is in thousands (eg: y = 1 means 1000). This further implies that the marginal cost is ($1000)/2000 = $0.50 = 50 cents. The marginal cost is the cost to make one extra unit.
The fraction 1/2000 converts to the decimal form 0.0005 after using a calculator. So m = 0.0005 is the decimal form of the slope.
The y intercept of the blue line is b = 1 as this is the location where the blue line crosses the vertical y axis. The y intercept represents the fixed costs needed to set up production, for example: buying the machinery needed is a fixed cost.
-------------------
Since m = 0.0005 and b = 1, we go from y = mx+b to y = 0.0005x+1
We could say y = (1/2000)x + 1, though I think it's probably easier to use a decimal in this case.
What is the equation of the line (0, 0) (3, -9)
Answer:
y= -3x
Step-by-step explanation:
Find the slope
-9-0/3-0 = -9/3
Simplify = -3
Plug into point-slope formula
y-y1=m(x-x1)
y-0=-3(x-0)
y= -3x
