Step-by-step explanation:
9 X 9 = 81
Answer:
No she doesn't have enough paint.
Step-by-step explanation:
You have to find the area of both walls then subtract both areas by 250. It would give you a negative number, meaning there is not enough paint.
A) 25% of males preferred playing sports.
Explanation) .25 is the same is 25%.
B) 25% of the people surveyed preferred reading a book.
Explanation) You have to add up how many males and females rather
to read a book. It's .10 + .15 = 25%.
C) 70 females were surveyed out of 200 people.
Explanation) Add up .15 + .5 + .15 to get .35. Put .35 multiplied by 200 to get 70.
Answer:
The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2π. So, a coefficient of b=1 is equivalent to a period of 2π. To get the period of the sine curve for any coefficient b, just divide 2π by the coefficient b to get the new period of the curve.
Step-by-step explanation:
Tgα = tan(α) = sqrt(2)/1 = opposite/ adjacent
opposite = sqrt(2)
adjacent = 1
hypotenuse = sqrt(opposite^2 + adjacent^2)
= sqrt(sqrt(2)^2 + 1^2) = sqrt(3)
sin(α) = opposite/hypotenuse
= sqrt(2)/sqrt(3)
cos(α) = adjacent/hypotenuse
= 1/sqrt(3)
now we can calculate the value of
5sin²α+3cos²α / 3sin²α-5cos²α
... do the math
