Answer:

Pythagoras theorem) 85^2 = 77^2 +|XY|^2. Step 2 |XY|^2 = 7225 - 5929, = 1296. Get square root to find value or length of the line XY.= 36 units. Tan Y = opposite ÷ adjacent = 77÷36. Angle in degrees = Tan^(-1)(77÷36) = 64.94 degrees.

Answer:

Step-by-step explanation:

ok, so you tangent is opposite/adjacent. You need to find the adjacent side. You could do a^2+b^2=c^2.A and B are the legs and c is the hypotunese. 85^2-77^2=b^2. This solves to b being 36. This means the adjacent side is 36 and opposite being 77. The tangent of Y is 77/36.

Finding Derivatives Implicity In Exercise, find dy/dx implicity.<br> 4x3 + ln y2 + 2y = 2x

lisov135 [29]

Answer:

$\frac{dy}{dx}=\frac{y(1-6x^2)}{(1+y)}$

Step-by-step explanation:

Given function : 4x³ + ln(y²) + 2y = 2x

on differentiating both sides with respect to 'x', we get

$\frac{d(4x^3 + ln(y^2) + 2y)}{dx}= \frac{d(2x)}{dx}$

$12x^2+\frac{2}{y}(\frac{dy}{dx})+2(\frac{dy}{dx})=2$

$12x^2+(\frac{2}{y}+2)\frac{dy}{dx}=2$

$(\frac{2+2y}{y})\frac{dy}{dx}=2-12x^2$

$\frac{dy}{dx}=\frac{y(2-12x^2)}{2+2y}$

$\frac{dy}{dx}=\frac{2y(1-6x^2)}{2(1+y)}$

$\frac{dy}{dx}=\frac{y(1-6x^2)}{(1+y)}$

A sport watch with an original price of $86 is on sale for $60.20. What is the percent of discount?

Anarel [89]

You need to first calculate the amount of lost money, which is 86-60.2=25.8 To find the discount, you need to put this over the initial price, or 86. This equals 0.3, which is 30 percent.
