the height of a triangle is 4 less than it’s base. The area of the triangle is 30 square inches. Find the length of the base to

Arisa [49]

Answer:

10 inches

Step-by-step explanation:

The formula for the triangle area is the following:

A = b * h / 2

Where b is the length of the base side and h is the height.

So, as the height is 4 less than the base, we have that:

h = b - 4

Using this value in the area equation, we have that:

A = b * (b - 4) / 2

30 = (b^2 - 4b) / 2

b^2 - 4b = 60

b^2 - 4b - 60 = 0

Using Bhaskara's formula to solve the quadratic equation, we have:

Delta = 4^2 + 4*60 = 256

sqrt(Delta) = 16

b1 = (4 + 16)/2 = 10

b2 = (4 - 16)/2 = -6 (negative value does not fit for this problem)

So the length of the base is 10 inches.

Jessica ran on the track team at her school. She finished the 200-meter race in 54 seconds. What was jessica's average speed,in

Scrat [10]

Answer:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race

Step-by-step explanation:

The problem provides for this case the amount of distance travelled by Jessica in a given time. And we know that travels 200m in 54 seconds.

We want to find the average speed and we can use the following formula:

$v =\frac{x}{t}$

Where x represent the distance and t the time if we replace the info given we got:

$v = \frac{200m}{54 s} =3.704 \frac{m}{s}$

Then the average speed for this case in m/s is 3.704 for the 200 meter race

Find the inverse of the function f(x) = (x - 4) 2 - 5 if x ≥ 4.

Serggg [28]

Same here, we do a quick switcharoo on the variables first,

$\bf \stackrel{f(x)}{y}=(x-4)^2-5\qquad inverse\implies \boxed{x}=\left( \boxed{y}-4 \right)^2-5
\\\\\\
x+5=(y-4)^2\implies \pm\sqrt{x+5}=y-4\implies \pm\sqrt{x+5}+4=y$
