The answer is A(87).I just plugged the numbers into the Pythagorean Theorem. 200^2 - 180^2 = the square root of 7,600, which equals about 87.

The park side length by the lake as given  180 meters.The  walking path is in  the shape of a rectangle with diagonal 200 square meters. Angles of a rectangle are 90 degrees.We have a right triangle with diagonal as the hypotenuse ,one of the leg as 180 meters and we need to find the adjacent side of the side by the lake that is the other leg

Pythagorean Theorem states: that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Or ,c^{2}=a^{2}+b^{2}. Where a,b are the legs of the triangle and c is the hypotenuse.

Substituting the values of c and a we have:

200^{2}=180^{2}+b^{2}.

Or 40000=32400+b^{2}.

Subtracting 32400 both sides ,

b^{2}=7600.

Or b= 87.17.= 87 m.

The side adjacent to the side by the lake is 87m.

Option A is the right answer.

Solve the following proportion for v. V/13=11/13
NeX [460]

Answer:

V = 11

Step-by-step explanation:

All you have to do here is to multiply both sides of this equation by 13.  This will eliminate the fractions.  You'll be left with V = 11.

What is the y-intercept of the polynomial f(x)f(x) f(x) defined below? Write the y-value only. f(x)=−4x2+x5+10x3+5x+8x4f(x)=-4x^
zhannawk [14.2K]

Answer:

y = 0

Step-by-step explanation:

Given

f(x) = 4x² +x⁵ +10x³ +5x+8x⁴

Required

Determine the y intercept

The y intercept of a function is a point where x = 0

So, we have to substitute 0 for x in the above function

f(x) = 4x² +x⁵ +10x³ +5x+8x⁴ becomes

f(0) = 4(0)² +(0)⁵ +10(0)³ +5(0)+8(0)⁴

f(0) = 4 * 0 + 0 + 10 * 0 + 5 * 0 + 8 * 0

f(0) = 0 + 0 + 0 + 0 + 0

f(0) = 0

Substitute y for f(0)

y = 0

Hence, the y intercept is 0
