Given \tan A = \frac{7}{{24}}, find the cos B
Natali5045456 [20]

We are given

tan(A)=\frac{7}{24}

we know that

tan(A)=\frac{opposite}{adjacent}

so, we get

opposite =7

adjacent=24

now, we can find hypotenuse

hypotenuse=\sqrt{7^2+24^2}

hypotenuse=25

now, we can draw triangle and then switch vertices accordingly

we can find cos(B) using second triangle

cos(B)=\frac{adjacent}{hypotenuse}

In second triangle:

adjacent=7

hypotenuse =25

so, we get

cos(B)=\frac{7}{25}................Answer

A kitten and a puppy found a sausage which is 14cm long and started eating it simultaneously from each end. The kitten is eating
julsineya [31]

It takes them 12 seconds to eat the whole sausage.

<h3>What is speed?</h3>

Speed is the rate of change of distance.

Analysis:

If kitten eats x cm, then puppy will eat 14 - x cm

speed = d/t

speed of kitten = 1/2

speed of puppy = 2/3

1/2 = x/t

2/3 = 14 - x / t

t = 2x--------1

2t = 3(14 - x ) -------- 2

substitute t in equation 2

2(2x) = 3(14 - x)

4x = 42 - 3x

7x = 42

x = 42/7 = 6cm

substitute value of x in equation 1

t = 2(60 = 12 seconds.

In conclusion, it takes the both animals 12 seconds to finish the sausage.

A ball is thrown upward with an initial velocity of 96 ft/sec from a height 640 ft. Its height​ h, in​ feet, after t seconds is
olchik [2.2K]
Check the picture below.

thus is at 0 = -16t² + 96t +640,

\bf 0=-16t^2+96t+640\implies 0=-16(t^2-6t-40)&#10;\\\\\\&#10;0=t^2-6t-40\implies 0=(t-10)(t+4)\implies t=&#10;\begin{cases}&#10;\boxed{10}\\&#10;-4&#10;\end{cases}

well, clearly it can't be a negative value for the elapsed seconds, so it can't be -4.

The age of father is 4nyears.If the age of his daughter is(2n-9)years.find their total age.​
8_murik_8 [283]

Answer:

4n+(2n-9)

4n+2n-9

6n-9 =the total age

6n=9

divide by 6 both sides.

n=9/6

n=1.5 years.

substitute the value of n in the age of the father and the daughter.

Age of father=4×1.5

6years.

Age of Daughter = (2×1.5)-9

3-9

=-6 years

Total age

6-6=0
