Use the lengths of corresponding sides
so answer is 16:40 which simplifies to 2:5.
First pair goes to f(x) = 20x
Next pair goes to f(x) = 10x + 20
Third pair goes to f(x) = 10x + 25
Last pair goes to f(x) = 20x + 10
Answer:
Step-by-step explanation:
If the degree of the polynomial is even (positive) ends of the function will either upwards or downwards on axis.
If the coefficient of the leading term of a polynomial is negative, both the ends of the graph will move downwards.
The given function is,
f(x) = -x⁴ + 9
Degree of the polynomial = 4
Coefficient of the leading term = -1
Therefore, ends of the polynomial will open downwards.
Answer:
10
12.5% less than 80 = 10
Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 80=100%
Step 4: Similarly, x=12.5%
Answer:
<h3>dn = -7^n-1</h3>
Step-by-step explanation:
Given the sequence -1,-7,-49,-343,....
We are to find the nth term of the sequence
dn = ar^n-1
a is the first term = -1
r is the common ration = -7/-1 = -49/-7 = 7
n is the number of terms
Substitute
dn = -1(7)^n-1
dn = -7^n-1
hence the nth term of the sequence is dn = -7^n-1
