Answer:
the sequence is the a geometric sequence because the terms has a common ratio. the common ratio = -80 / 200 = -2 / 5common ratio = 32 / -80 = -2 /5
so the next to term can be solve multiplying the last term with the common ratio
x = -12.8 ( -2 / 5)x = 5.12
y = 5.12 ( - 2 / 5)y = -2.048

15. Annual sales for a surf shop are $130,000
and are increasing at a rate of 7% per year; 7 years
find the Function and the
Value after 7 years
Answer:
[tex]P(7)=\$208,752[/tex]
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
[tex]P(t)=P_o(1+r)^t[/tex]
Where P(t) is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
It's given the annual sales for a surf shop are Po=$130,000. They are increasing at a rate of r=7% = 0.07 per year. Substituting values, the function is:
[tex]P(t)=\$130,000(1+0.07)^t[/tex]
[tex]\boxed{P(t)=\$130,000(1.07)^t}[/tex]
The value of the function after t=7 years is
[tex]P(7)=\$130,000(1.07)^7[/tex]
Computing:
[tex]P(7)=\$130,000*1.6058[/tex]
[tex]\mathbf{P(7)=\$208,752}[/tex]

Answer: same bro
Step-by-step explanation:
Answer:
So basically the hypotenuse will be the side directly opposite from the right angle (the square marked on the triangle), it will always be the longest side
the "opposite" will be the side directly across from the curved angle marked
the "adjacent" will be the side that the curved angle touches, i.e. the one "next to it"

The depth, d , of a lake is 57 m, rounded to the nearest integer. Write the error interval for d in the form a ≤ d < b .
Given:
The depth, d , of a lake is 57 m, rounded to the nearest integer.
To find:
The error interval for d in the form a ≤ d < b.
Solution:
The depth, d , of a lake is 57 m, rounded to the nearest integer.
If the depths of the lake is 56.5m or greater than this up to 57 m, then the depth, d , of a lake is 57 m, rounded to the nearest integer.
[tex]56.5\leq d\leq 57[/tex] ...(i)
If the depths of the lake is 57m or greater than this up to 57.5 m but not 57.5 m, then the depth, d , of a lake is 57 m, rounded to the nearest integer.
[tex]57\leq d<57.5[/tex] ...(ii)
Using (i) and (ii), we get
[tex]56.5\leq d<57.5[/tex]
Therefore, the error interval for d is [tex]56.5\leq d<57.5[/tex].

What is Angle Sum Property?To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.
The formula for calculating the sum of interior angles is ( n − 2 ) × 180 where n is the number of sides.
Given:
We have Heptane and the sum of Angles of Heptane is
= 180 ( n-2)
= 180 (7-2)
= 900
Now, using Angle Sum Property
145 + 133 + 140 + x + 125 + 119 + 117 = 900
779 + x =900
x= 900- 779
x = 121
Hence, the measure of x is 121.

Determine whether the relation (7,4), (5.-1), (3, -8), (1, -5), (3,6) is a function. Explain.
Answer:
No it is not a function
Step-by-step explanation:
it is not because of the sets of data (3,-8) and (3,6). as you can see the x values are the same( 3 is the x value in each set) and the y vaues (-8 and 6) are different.

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 2, and the given zeros. -4,0,2,4
Answer:
A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;
f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x
Step-by-step explanation:
The given parameters of the polynomial are;
The leading coefficient of the polynomial = 2
The zeros of the polynomial = -4, 0, 2, 4
We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)
For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'
To have a leading coefficient of 2, we can add '2' as a factor of the polynomial
Therefore, we can have the factors of the polynomial as follows;
(x² - 4²)·2·x×(x - 2) = 0
From the above equation, using a graphing calculator, we get the following possible polynomial;
(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0
Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.

Two points in the (x, y) plane are a distance of 5 units apart. After a certain transformation is applied to both points, the two new points are 10 units apart. What was the transformation?
Answer:
translation
Step-by-step explanation:
Based on the information provided the type of transformation would have been a translation of one or both points. This means that either one or both points were moved. If only one point was moved it would have moved 5 units. If both were moved equally then they would have moved 2.5 units apart. Since we are not told the initial and end values of each point we cannot tell if the translation was a vertical or horizontal translation.

Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answer:
x = -4, y = 9
or
(-4, 9)
Step-by-step explanation:
x - 5y = -49
y = -2x + 1
substitute y for -2x + 1
x - 5(-2x + 1) = -49
x + 10x - 5 = - 49
add 5 to both sides
x + 10x - 5 + 5 = - 49 + 5
x + 10x = -44
11x = -44
divide both sides by 11
11x/11 = -44/11
x = -4
substitute x for -4 in any of the original equations
y = -2x + 1
y = -2 * -4 + 1
y = 8 + 1
y = 9
Answer:
x = -4, y = 9 or (-4,9)
