Answers

Answer 1

H. 12 ft

Given c=15, and a=9, you can use Pythagorean’s theorem a^2+b^2=c^2 to find b, the height

9^2+b=15^2

81+b^2=225

b^2=144

b=12

Height = 12

Answers

Step-by-step explanation:

I'll assume you meant f(x) = 3 - 2x and not t(x) = 3 - 2x

[tex] \frac{3 - 2x}{ \frac{1}{x + 5} } \times 8[/tex]

[tex]((3 - 2x) \times ( \frac{x + 5}{1} )) \times 8[/tex]

[tex]((3 - 2x)(x + 5)) \times 8[/tex]

[tex]( - 2 {x}^{2} - 7x + 15) \times 8[/tex]

[tex]( \frac{f}{g}) \times 8 = - 16 {x}^{2} - 56x + 120[/tex]

What 6x squared divided by x is

Answers

Answer:

[tex]6x[/tex]

Step-by-step explanation:

Hey there!

In order to solve this problem, you need to first simplify the equation by splitting [tex]6x^2[/tex]

After splitting:

[tex]\frac{6*x*x}{x}[/tex]

Now, we can cross out two of the x values

[tex]\frac{6*x}{1}[/tex]

This is also seen as

[tex]6*x[/tex]

Which simplified is our answer

So the fraction [tex]\frac{6x^2}{x}[/tex] can be re-written or solved as, [tex]6x[/tex]

Answer:

[tex]\frac{6x^{2}}{x} =6x[/tex]

Step-by-step explanation:

[tex]x\neq 0\\\\\frac{6x^{2}}{x} =\frac{6\times x\times x}{x} =6x \ \ \ \ (x \ can \ be \ cancelled \ out)[/tex]

Example :

[tex]\frac{6\times 3^{2}}{3} =\frac{6\times 9}{3} =\frac{54}{3} =18[/tex]

[tex]\frac{6\times 3^{2}}{3} =\frac{6\times 3\times 3}{3} =6\times3=18[/tex]

Answers

Answer:

Quotient = division of one number by another

[tex]\implies \textsf{quotient of 30 and 6} = \sf \dfrac{30}{6}[/tex]

[tex]\implies \textsf{3 subtracted from } \sf \dfrac{30}{6}=\dfrac{30}{6}-3[/tex]

The quotient of 30 and 6 can also be written as the ratio 30 : 6

Therefore, the solution is (30:6) - 3

Let's see

Quotient means division

t takes 12 hours for half of the He in a container to leak out. If the same container is refilled with Ne, how long will it take for half of the Ne to leak out

Answers

The time taken by the Ne to come out of the container will be 26.83 hours

What will be the time?

Here it is given in the question that it takes 12 hours for half of the He in a container to leak out If the same container is refilled with Ne then time taken by the Ne gas to leak will be calculated from the formula

[tex]\dfrac{V_{He}}{t_{He}}\times \dfrac{t_{Ne}}{V_{Ne}}=\sqrt\dfrac{M_{Ne}}{M_{He}}[/tex]

Since the volume of both the gases will be same so

[tex]V_{He}=V_{Ne}[/tex]

[tex]\dfrac{t_{Ne}}{t_{He}}=\sqrt5[/tex]

[tex]t_{Ne}=12\times \sqrt5[/tex]

[tex]t_{Ne}=12\times 2.236[/tex]

[tex]t_{Ne}=26.83\ hours[/tex]

Hence the time taken by the Ne to come out of the container will be 26.83 hours

Answer:

Step-by-step explanation:

given an exponential function in the form y = a[tex]b^{x}[/tex]

to find a and b use the coordinate points it passes through

using (0, 4 ) , then

4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , that is

a = 4 , so

y = 4[tex]b^{x}[/tex]

using (2, 100 )

100 = 4b² ( divide both sides by 4 )

25 = b² ( take the square root of both sides )

[tex]\sqrt{25}[/tex] = b , that is

b = 5
