Answer:

85 cents

Step-by-step explanation:

Let a represent the price of pineapples

Let p represent the price of peaches

74p + 9a= 14p + 21a

p = 17 cents

Substitute 17 for p

74(17) + 9a = 14(17) + 21a

1258+9a= 238+21a

1258-238= 21a-9a

1020= 12a

a= 1020/12

a= 85

Hence the price of pineapples is 85 cents

You throw a water balloon straight up with a velocity of 14 m/s. What is it’s max height?
Kay [80]

Answer:

y_m_a_x=10m

Step-by-step explanation:

The max height of an object can be calculated using one the basic projectile motion equations:

y_m_a_x= \frac{v^2*sin^2(\theta)}{2g}

Where:

g=Gravitational\hspace{3}constant\\v=Velocity\hspace{3}of\hspace{3}the\hspace{3}object\\\theta=Launch\hspace{3}angle

In this case, let's asumme g=9.8m/s^2, besides θ=90, because the water ballon was threw straight up, so:

y_m_a_x= \frac{v^2*sin^2(\theta)}{2g}=\frac{(14^{2})*sin^2(90) }{2*9.8}=\frac{196*1}{19.6}=10m

The leaning tower of Pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. How tall was the lean
Marizza181 [45]

Answer:

56 meters.

Step-by-step explanation:

Please find the attachment.

Let the leaning tower's be h meters tall, when it was originally built.

We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.

Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

\text{Cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}

Upon substituting our given values we will get,

\text{Cos (4)}=\frac{55.86}{h}

h=\frac{55.86}{\text{Cos (4)}}

h=\frac{55.86}{0.99756405026}

h=55.996\approx 56                      

Therefore, the leaning tower was approximately 56 meters, when it was originally built.

Please help, I’ll mark as brainliest.
Crazy boy [7]

Step-by-step explanation:

H(x)=

\frac{f(x)}{g(x)}

If g(x) values =0, h(x) will be undefined.

So f(x)=0, h(x) will be undefined.

Zo find values of f(x) equal 0.

That is when x=2. So the answer to first solution is 2.

h(x) is negative when (-oo, -3) U (2,oo)
