10 points. y = a(x-h)^2 + k

Advocard [28]

Answer:

Option A $\textbf{a}=\frac{\textbf{y-k}}{(\textbf{x-h})^2}$

Step-by-step explanation:

Verification: The given equation is

$y=a(x-h)^2+k$

$y-k=a(x-h)^2$

$\frac{y-k}{(x-h)^2}=a$

which may be written as

$a=\frac{y-k}{(x-h)^2}$

Question 11 Working together, it takes two different sized hoses minutes to fill a small swimming pool. If it takes minutes for

Annette [7]

Answer:

x = 12 hrs to fill the pool

Step-by-step explanation: INCOMPLETE QUESTION

Missed information:

Time for two different sizes hoses to fill a small simming pool (let say that is 3 hours)

Time for one of the two hoses to fill a small simming pool ( lt say that is 4 hours)

With that information we can answer the question

If one of the hoses fill the pool in 4 hours, it will fill 1/4 of the pool in 1 hour

We dont know the other hose how long it take to fill the pool so let call that time x hours then in 1 hour it will fill 1/x of the pool

In 1 Hour the two hoses will fill 1/3 of the pool then

In one hour

1/4 + 1/x = 1/3 Solving for x

( x + 4 )/ 4x = 1/3

3x + 12 = 4x

- x = -12 x = 12 hours

HELP i can’t figure this out

Agata [3.3K]

Answer:

m∠B = 66.3°

a = 0.0319

b = 0.0726

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

⇒ m∠A + m∠B + m∠C = 180°

⇒ 23.7 + m∠B + 90 = 180

⇒ m∠B = 180 - 90 - 23.7 = 66.3°

We can use the sine rule to help solve the missing side lengths.

$\dfrac{a}{sin(A)}=\dfrac{b}{sin(B)}=\dfrac{c}{sin(C)}$

where A, B and C are the angles and a, b and c are the side lengths opposite the angles.

Therefore,

$\dfrac{a}{sin(23.7)}=\dfrac{b}{sin(66.3)}=\dfrac{0.0793}{sin(90)}$

$\implies a=\dfrac{0.0793}{sin(90)}\times sin(23.7)=0.031874458...=0.0319$

$\implies b=\dfrac{0.0793}{sin(90)} \times sin(66.3)=0.072612043...=0.0726$
