Imagine the shadow and the building height forms a right angle triangle; 

We know the height and the shadow make up the "legs" of the triangle, 

a²+b²=c²
(750)²+(111)²=c²
562500+12321=c²
574821=c²
c=√574821 
c=758.169 ≈ 758.2 ft 

Hope I helped :)

Multiply.
prohojiy [21]

Answer:

D. 3x² + 19x - 14

Step-by-step explanation:

Use FOIL to find the answer.

First: x * 3x = 3x²

Outer: -2 * x = -2x

Inner: 3x * 7 = 21x

Last: 7 * -2 = -14

Form the equation:

3x² - 2x + 21x - 14

Combine like terms.

3x² + 19x - 14

There are 10 coconuts at-the base of your tree. The coconuts are falling off the tree at a rate of 6 coconuts per week. Assume t
Sphinxa [80]

Answer: y = 6x +10.

After 7 weeks there will not be any coconut on the tree.

Step-by-step explanation: Given initial number of coconuts under the tree = 10 coconuts.

The rate of falling of coconuts each week = 6 coconuts per week.

Let us assume number of weeks be x and y be total number of coconuts after x weeks.

So, total number of coconuts after x weeks would be = Rate of falling of coconuts × number of weeks + Initial number of coconuts.

Therefore,

y = 6x +10.

a) y = 6x +10

Let us graph the linear equation with y-intercept 10 and slope rise/run = 6/1.

b) Total number of coconuts after x weeks = 52.

Plugging y=52 in above equation, we get

52 = 6x+10.

Subtracting 10 from both sides, we get

52-10 = 6x=10-10

42 = 6x.

Dividing both sides by 6, we get

42/6 = 6x/6

7 = x.

Therefore, after 7 weeks there will not be any coconut on the tree.

Solve for the variable c in this equation:<br><br> a(b – c) = d
Aleksandr-060686 [28]

a(b – c) = d

ab - ac = d

subtract ab to both sides

-ac = d - ab

divide both sides by (-a)

c = (d-ab)/-a

simplify

c = -d/a + b
