Solution: y=2x-11

Step by step solution:
f(x)=(x+1)2-7
f(x)=2x+2-7
f(x)=2x-5
y=2x-5
When it’s translated 3 to the right the y intercept is 3 less if the slope is 1, but since the slope is 2 there the difference is 6, so the y intercept is 6 less than it was before
y=2x-11

Solve the equation below using a graphing

UNO [17]

Answer:

Step-by-step explanation:

The given equation is:

$e^x-\ln 2x = 3.7$

Moving all terms to the left side:

$e^x-\ln 2x - 3.7=0$

Now we define a function:

$y=f(x)=e^x-\ln 2x - 3.7$

The solutions of the equation are the values of x such that y=0.

Since the function cannot be solved by algebraic methods, we use a graphing tool.

Those points where the graph crosses the x-axis are solutions of the equation.

Please refer to the graph in the figure below.

We can clearly identify there are two solutions at

x = 0.05

x = 1.57

Three numbers are in the ratio 3:4:5. If the sum of their cubes is 216000, find the largest of these three numbers.

Makovka662 [10]

Answer:

Step-by-step explanation:

Let the numbers be 3x, 4x, 5x

(3x)^3 + (4x)^3 + (5x)^3 = 216000

27x^3 + 64x^3 + 125x^3 = 216000

216x^3 = 216000

x^3 = 1000

x = 10

5x = 5(10) = 50

Answer: 50

Using the formula for initial velocity h=-16t2+VT the height of any object can be found by the time, Annalee serves a volleyball

Marrrta [24]

The ball will hit the ground at 0.125 seconds

<h3>Quadratic function</h3>

The equation of the function is a quadratic function, and the function is given as:

$h = -16t^2 + 2t$

When the ball hits the ground, the value of h is 0.

So, the equation of the function becomes

$-16t^2 + 2t = 0$

Subtract 2t from both sides of the equation

$-16t^2 =- 2t$

Divide both sides by -2t

$8t =1$

Divide both sides by 8

$t =0.125$

Hence, the ball will hit the ground at 0.125 seconds

Which of the two solids below are similar ?

Pachacha [2.7K]

Answer: I and II.

Step-by-step explanation:

By definition, two solids are similar if their corresponding sides are in the same ratio.

Knowing this, let's find which solids are similar:

Corresponding sides ratio of solids I and II:

$\frac{3}{2}=\frac{2}{\frac{4}{3}}=\frac{5}{\frac{10}{3}}$

$\frac{3}{2}=\frac{3}{2}=\frac{3}{2}$

Corresponding sides ratio of solids I and III:

$\frac{3}{\frac{9}{2}}=\frac{2}{3}=\frac{5}{8}$

$\frac{2}{3}=\frac{2}{3}=\frac{5}{8}$

Corresponding sides ratio of solids II and III:

$\frac{2}{\frac{9}{2}}=\frac{\frac{4}{3}}{3}}=\frac{\frac{10}{3}}{8}}$

$\frac{4}{9}=\frac{4}{9}=\frac{5}{12}$

You can observe that the solids I and II are similar.
