Answer:
- 1 cm to 40 m
- 1/40 cm to 1 m
Step-by-step explanation:
The problem statement isn't clear as to which unit is 1 in your unit rate. If it is 1 cm, you can find the unit rate by multiplying the reationship by 4:
... 4 × (1/4 cm to 10 m) = 1 cm to 40 m
If it is 1 m, you can find the unit rate by multiplying the relationship by 1/10:
... 1/10 × (1/4 cm to 10 m) = 1/40 cm to 1 m

<em>Additional comment on the problem</em>
Ordinarily, drawing scales are expressed as a fraction. Here, that would be ...
(1/4×1/100 m)/(10 m) = 1/4000 . . . or . . . 1 : 4000
Answer:
The first option
.
Step-by-step explanation:
To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be
. This eliminates the bottom two solutions.
In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like

This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.
Only answer choice 1 meets the requirement.
Answer:
x
Step-by-step explanation:
Answer:
f(x)=19(2)^x
Standard form of exponential graph is f(x) = ab^x
Plugging in (0, 19), you get
19 = ab^0 -> 19 = a(1)
a=19
f(x)=19b^x
1216 = 19(b)^6
64=b^6
b=2
-> f(x) = 19(2)^x
