Answer:
1. 7¹⁰
2. 9⁸
Step-by-step explanation:
1. 7 = 7¹
Hence, using the rules of indices..... you would add the exponents when numbers that have the same base are multiplied together.
7⁹⁺¹ = 7¹⁰
2. Add exponents
9²⁺⁶ = 9⁸
Answer:
The worth of truck is $2,201 more after 2 years than after 3 years.
Step-by-step explanation:
Given: 
The value of truck is depreciate per year using above formula.
We need to find how much more worth of truck after 2 years than 3 years.
First we find the worth of truck after 2 years, put x=2 into formula
The worth of truck after 2 years would be $27,508
Now we find the worth of truck after 3 years, put x=3 into formula
The worth of truck after 2 years would be $25,307.36
Now we find difference of both value.
Difference = 27508-25307.36 = $2,201
Hence, The worth of truck is $2,201 more after 2 years than after 3 years.
I think there are 9,999 outcomes. If you think about it, how many four digit number can you you come up with. It wouldn't be 10,000 because that's a five digit number. Hope this helped in a way! :)
The required equation of the parabola is (y-5)² = 20(x+2)
<h3>Equation of a parabola</h3>
The standard equation of a parabola is expressed as;
(y-k)² = 4p(x-h)
where;
vertex = (h, k)
focus = (p+k, k)
directrix x = -p + h
Note that the directrix given will determine the type of the equation of a parabola
Given the following parameters
focus = (-2, 5) = (h, k)
x = -p + h
3 = p -2
p = 5
Substitute
(y-k)² = 4p(x-h)
(y-5)² = 4(5)(x-(-2))
(y-5)² = 20(x+2)
Hence the required equation of the parabola is (y-5)² = 20(x+2)
