Vonna scored 35 goals at soccer practice. Her ratio of goals to misses was 5:8. How many times did she miss?

Digiron [165]

<u>Answer:</u> She misses 56 times at a soccer practice.

<u>Step-by-step explanation:</u>

Let the goals she misses be 'x'.

According to the question:

$5:8::35:x$

These two ratios follow direct relationship, so:

$\frac{5}{8}=\frac{35}{x}\\\\5x=35\times 8\\\\x=\frac{280}{5}\\\\x=56$

Hence, Vonna misses 56 times at a soccer practice.

The equation h(t)= -16t^2+864t models the path of a rocket shot into the air. After how many seconds does the rocket hit the gro

Vika [28.1K]

Answer:

t = 54 seconds

Step-by-step explanation:

The equation that models the path of a rocket into the air is given by :

$h(t)= -16t^2+864t$

It is required to find the time after which the rocket will hit the ground. When it hits the ground, the height of the rocket will becomes zero. It means,

h(t) = 0

i.e.

$-16t^2+864t=0\\\\16t(-t+54)=0\\\\16t=0, -t+54=0\\\\t=0\ and\ t=54\ s$

It means after 54 seconds, the rocket will hit the ground.

Write the equation of this circle in standard form

Svetradugi [14.3K]

Answer:

Standard equation of this circle is (x +5)² + y² = 9.

Step-by-step explanation:

The equation of a circle with center at (h,k) and a radius of r is:

(x - h)² + (y - k)² = r²

Subtitute the variables with h= -5, k = 0, and r = 3

(x - (-5))² + (y - 0)² =3²

(x + 5)² + y² = 9
