Take into account the length of the right side of the figure is 10. Moreover, x is the hypotenuse of a right triangle. To find the value of x, use the sine function:
cos 45 = opposite side/hypotenuse
cos 45 = 10/x solve for x
x = 10/cos 45
x = 10/0.707
x = 14.14
with the previous value of x, you can find y. Again, consider the right triangle right side. x is the hypotenuse. Use the Pythagorean theorem to find y:
x² = 10² + y² solve for y and replace x
y² = x² - 10²
y² = (14.14)² - 100
y² = 200 - 100
y² = 100 apply square root both sides
y = 10
Hence, the values of x and y are 14.14 and 10 respectively
D
graph becomes slimmer, so definitely be multipled 1/2
D. both climbers rested on the wall for 2 minutes
3x=x+40(vertically opposite angle)
thus ,
X= 20
Answer:
B. Sum difference, product, power
Step-by-step explanation:
To evaluate this limit we need to know how to get the limits involving sums and differences. Since powers are involved we need the power rule too. We use the product rule instead of the quotient rule because the fraction can be written as a product with a negative power.
