A ball is thrown vertically upward from the ground. Its distance in feet from the ground in t seconds is s=−16t2+192t. After how
steposvetlana [31]

Answer:

t=7seconds or 5seconds

Step-by-step explanation:

s=-16t^2 +192t

let s=560ft

560=-16t^2 +192t

16t^2 -192t+560=0

16(t^2-12t+35)=0

(t^2 -12t +35)=0

factoring it ,it will give

(t-7)(t-5)=0

solving for t

t-7=0 or t-5=0

t=7s or t=5s

If the length of the shorter leg of a right triangle is 5 cm and the length of the hypotenuse is 13 m, find the length of the lo
Delvig [45]

Answer:

2 cm (Answer B)

Step-by-step explanation:

This is a right triangle, and therefore the Pythagorean Theorem applies:

(shorter leg)² + (longer leg)² = (hypotenuse)²

In this case, (longer leg)² = (hypotenuse)² - (shorter leg)², or

(longer leg)² = (13 cm)² - (5 cm)², or:

(longer leg)² = 169 cm² - (25 cm²) = 144 cm²

The length of the longer leg is the square root of 144 cm², or 12 cm (Answer B)

there are some pets in a pet shop. 36% of them are rabbits, 28% of them are dogs and the rest are hamsters. If there are 160 dog
guapka [62]

Answer:

250

Step-by-step explanation:

36% are rabbits, and 28% are dogs.  That means the percent that are hamsters is:

100% − 36% − 28% = 36%

There are 160 dogs and hamsters, which are 28% + 36% = 64% of the pets.  Therefore, we can write and solve a proportion:

160 / 64% = x / 100%

x = 250

There are a total of 250 pets.

Identity the function that models a ball being thrown in the air with an initial velocity of 32ft/s, from a hight of 20 ft
Salsk061 [2.6K]
\bf \qquad \textit{initial velocity}\\\\
h = -16t^2+v_ot+h_o \qquad \text{in feet}\\
h = -4.9t^2+v_ot+h_o \qquad \text{in meters}
\\ \quad \\

v_o=\textit{initial velocity of the object}\\
h_o=\textit{initial height of the object}\\
h=\textit{height of the object at "t" seconds}\\\\
-----------------------------\\\\

\begin{cases}
v_o=32\\
h_o=20
\end{cases}\implies \boxed{h(t)=-16t^2+32t+20}
