Step-by-step explanation:
SinA + CosA × TanA
=0 + 1 x 0
=0
Step-by-step explanation:
1/2 represents every fraction, where the denominator (bottom part) is twice the numerator (top part).
like 4/8 or 6/12 or 128/256 or ...
what do we need in the denominator to calculate with 15/16 ?
the same : 16.
and what is half of 16 ? 8.
so, we need the 1/2 based on 16th = 8/16.
so, the dog ate 8/16 (1/2) of the original 15/16.
what was left was
15/16 - 8/16 = 7/16 pound
SOLUTION:
Step 1:
The length of a rectangular garden is 8 feet longer than its width.
If the garden's perimeter is 184 feet.
What is the area of the garden in square feet?
Step 2:
L = length
W = width
L = W+8
P = perimeter
P = 2(L+W)
P =184 (given)
Substitute L=W+8 in the perimeter equation
2( (W+8) + W ) = 184
(W+8) +W = 92
2W + 8 = 92
2W = 84
W = 42 ft ( Width = 8 feet )
L = W+8
L = 42+8
L = 50 ft ( Length = 50 feet )
Always check your work.
In this case, check the perimeter.
2(L+W) = ?
2(50+42) = 184 feet.
CONCLUSION:
Then, the question says:
It asks for the area in square feet.
A = Area
A = L*W
A = 50 ft * 42 ft
A = 2100 sq ft.
.
Answer:
21 feet (20.977)
Step-by-step explanation:
1. Draw a picture, it makes it much easier. Draw a right triangle with the vertical labeled 25 and the horizontal labeled X, then label the angle adjacent to the horizontal and hypotenuse 40°
2. Use tangent because X is opposite of 40 and 25 is adjacent to angle 40. the equation would be Tan40/1 = X/25
3. You then cross multiply to get 25Tan(40) = X
4 You then plug it into a calculator and get the full answer of 20.97749078, but I always round up to either 20.98 or 21 feet, whatever your teacher allows
So my title in Brainly isn't Expert and people probably don't call me that in real life, but we have been studying this in my math class.
Domain is the extent of X values while range is Y. The shown quadratic equation continues to the left an infinite amount as well as to the right. The answer is all real numbers since it continues to infinity both directions.
