The statement H(30) = H(25) + 5 means that, "when Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old"
<h3><u>Solution:</u></h3>
Given that,
Baby Amelia's parents measure her height every month
It is given that H(t) models Amelia's height (in centimeters) when she was "t" months old
Given statement is H(30) = H(25) + 5
So, we can say that H(30) = Amelia's height when she was 30 months old
H(25) = Amelia's height when she was 25 months old
So H(30) = H(25) + 5 means that,
Height of Amelia when she was 30 months old is 5 centimeter more than Amelia height when she was 25 years old
Or we can say that,
When Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old
Answer: The correct option is tan(F).
Explanation:
In the given figure the triangle is a right angle triangle because 
.
It is also given that 
and 
.
Since it is an isosceles right angle triangle, therefore the value of perpendicular and base is same for both angles D and F, which is 5.
The value of cos(F) is 
.
The value of sin(F) is .
The value of sin(D) is .
The value of tan(F) is 1. Which is not equal to .
The value of cos(D) is .
Therefore, the value of tan(F) is not equal to the value of cos(F), so the correct option is third.
Answer:
Her first coupon ti be used is $50 off a purchase above $300
Final purchase price= $340
Step-by-step explanation:
Marie has two coupons
one for a 15% discount and one for $50 off any purchase above $300.
The stores allow the two coupons to be combined and she spends a total of $450.
Her first coupon ti be used is $50 off a purchase above $300.
So Marie have $400 now
15% off $400= 400-(0.15*400)
15% off $400 = 400-60
15% off $400 =$ 340
