Answer:
(sin(A) + cos(A)).sec(A) = 17/12
Step-by-step explanation:
tan(A) = 5/12
sin(A) = 5/13
cos(A) = 12/13
sec(A) = 1/(cos(A)) = 13/12
(sin(A) + cos(A)).sec(A) = (5/13 + 12/13).13/12
= 17/13.13/12
= 17/12

Consider the graph of the function f(x)=10^x.
Using graph, the value of g(x) = 8 and the y- intercept at the point (0,-1).
What is graph?A graph is a "mathematical representation of a network and it describes relationship between lines and points".
According to the question,
f(x) = [tex]10^x[/tex]
g(x) = -4f(x) +12
g(x) = -4 (10ˣ) +12
The graph intersect at y-axis then x-coordinate should be zero.
Let take any two points on y-axis (0, 1) and substitute g(0) = -4 (10⁰) + 12
= 8
Hence, the value of g(x) = 8 and the y- intercept at the point (0,-1).

How many teaspoons are in 200 milliliters? 1 tsp = 5 ml 200 mL = [?] tsp
Answer: 40
Step-by-step explanation:
using dimensional analysis ( you might not have learned this yet, but it's basically multiplying things to cancel out units)...
200 ml * (1 tsp/ 5 ml) = 40 tsp
200 milliliters is equal to 40 teaspoons.
Here, we have,
given that,
1 tsp = 5 ml
so, we get,
If 1 teaspoon (tsp) is equal to 5 milliliters (ml),
then to find how many teaspoons are in 200 milliliters (mL),
we have to divide 200 by 5:
so, we get,
200 mL / 5 mL/tsp
= 40 teaspoons (tsp)
i.e. 200 ml * (1 tsp/ 5 ml) = 40 tsp
So, 200 milliliters is equal to 40 teaspoons.

Answer:
2.25 yards per costume
Step-by-step explanation:
if you want to find the unit rate of something put it into a fraction which is also considered dividing. Like if you want to figure out miles per hour or ounces per cup, just divide miles by hour, or divide ounces per cup to get your final answer. In this case divide 15.75 yards of fabric by 7 costumes to get your answer.
