Answer:
90/[10+(3-3-4)]=90/[10+(-10)]
90/(10-10)=90/0=0

Answer:
a)
b)
c)
d)
Step-by-step explanation:
We will use the following trigonometric identities
.
Recall that given a right triangle, the sin(theta) is defined by opposite side/hypotenuse. Since we know that the angle is in quadrant 2, we know that x should be a negative number. We will use pythagoras theorem to find out the value of x. We have that
which implies that . Recall that cos(theta) is defined by adjacent side/hypotenuse. So, we know that the hypotenuse is 7, then
b)Recall that , then using the identity from above, we have that
c) Recall that . Then,
d) Recall that and . Then
4/5 + 11/12
To add fractions they must have the same denominator (bottom number)
Let's change the denominators of our fractions to something else.
This new denominator should be divisible by the old ones (5 and 12)
Let's just use 5 × 12 = 60 as our denominator.
To get 4/5 to a denominator of 60--
The top and bottom of any fraction can be multiplied by the same number to get an equal fraction and essentially change the denominator.
We want to multiply 5 by something to get 60...
let's multiply the top and bottom of 4/5 by 12.
4/5 = 48/60
Now, 11/12.
We need to mulitply the top and bottom by 5 to get the bottom to 60.
55/60
Now instead of
4/5 + 11/12
we have
48/60 + 55/60
Let's add the numerators (top numbers).
(48+55)/60
103/60
If you need your answer as a mixed number:
103/60
60/60 + 43/60
The function sits with its starting point at the origin. The function is translated h units to the left or right and k units up or down. Since our radicand, the value under the square root sign, is x+7, putting that into our standard form it would be x-(-7) because minus a negative is a positive. So we move the parent graph to the left (-7 moves to the left) 7 units. There is no number k so our function is not moving up or down. Only to the left 7.
