the equation a equals 1 half b h, where b represents base and h represents height, is used to find the area of a .

NikAS [45]

The formula for b from the given area is equal to (2A / h).

As given in the question,

Formula to find area of a triangle is equal to A = (1/2) b h

b represents the base of the triangle

h represents the height of the triangle

A = (1/2) b h

Multiply both the side by 2 in area formula

2A = b h

Divide both the side by h

b = (2A) / h

Therefore, the formula for b from the given area is equal to (2A / h).

The complete question is:

The formula A = (1/2)b h represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b.

Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).

DochEvi [55]

Let $y=ab^x,$ as described in the problem statement. Plugging in $x=2$ and $x=5$ gives us the equations $18=ab^2$ and $60.75=ab^5.$ Since $a,b$ are nonzero, we divide the second equation by the first to get $\frac{27}{8}=b^3,$ which means that $b=\frac{3}{2},$ after taking the cube root. Plugging this value for $b$ into the first equation, we now have $18=a(3/2)^2=\frac{9a}{4}.$ Solving gives $a=8,$ and our desired exponential equation is $\boxed{y=8\left(\frac{3}{2}\right)^x}.$
