Answer:

Differentiation is concerned with things like speeds and accelerations, slopes and curves ect. These are Rates of Change, they are things that are defined locally. The Fundamental Theorem of Calculus is that Integration and Differentiation are the inverse of each other.

A sports store is having a 20% off sale on skis. The original price of the ski is $560.00

attashe74 [19]

Answer:

Total cost: 486.080$

Step-by-step explanation:

Original Price: 560.000$

Sale: 20%

Discount: 560.000$ * 20% = 112.000$

Discounted Price: 560.000$ - 112.000$ = 448.000$

Tax Rate: 8.5%

Tax: 448.000$ * 8.5% = 38.080$

Tax after Tax: 448.000$ + 38.080$ = 486.080$

Point P is outside a circle with center O and is 10 cm from the center. The circle has a radius of 5 cm. Lines PA and PB are two

Answer:

∠PAO = 90°
∠APO = 30°
∠AOB = 120°
PB ≈ 8.7

Step-by-step explanation:

A tangent makes a right angle with the radius to the point of tangency. Hence ∠PAO is 90°. The ratio of the short side (OA) of the right triangle OAP to the hypotenuse (OP) is 5 : 10 = 1 : 2. These are the ratios found in a 30°-60°-90° triangle, so we know that ∠APO = 30°.

OP is a bisector of angle APB, so that angle is 60°. Angle AOB is the supplement to angle APB, so ∠AOB = 120°.

As we said above, triangle OAP is a 30°-60°-90° triangle, so its side lengths have the ratios 1 : √3 : 2. This means PA = PB = 5√3 ≈ 8.7.
