So first, find out the total amount of money you make in 3 months.

If you make 1200 dollars a month, then in 3 months, you can make 3600 dollars. This is because 1 month salary + 1 month salary + 1 month salary = 3 month salary, and 1 month salary = 1200. So 1200 + 1200 + 1200 = 3600.

Since you're saving 2/5 of that, the simplest method to do this is to divide by 5, to find 1/5 of 3600, then multiply by 2 to find 2/5.

3600/5 = 720

720 * 2 = 1440

So you can save $1440 in three months.

Given triangle DEF similar to triangle GHF. Enter segments in the blanks provided that would result in a true equation.
Paul [167]

Given:

The triangles DEF is similar to GHF.

The objective is to find a similar ratio of DF/DE.

Explanation:

Using the basic proportionality theorem, for the similar triangles DEF and GHF,

\frac{DE}{GH}=\frac{DF}{GF}=\frac{EF}{HF}\text{ . . . .   ..  .(1)}

Considering the first two ratios of equation (1),

\frac{DE}{GH}=\frac{DF}{GF}

On interchanging the segments further,

\frac{DF}{DE}=\frac{GF}{GH}

Hence, the required segment in the blanks is GF/GH.

Determine (without solving the problem) an interval in which the solution of the given initial value problem is certain to exist
charle [14.2K]

Answer: t = - 5 ∈ I_{1} = ( -∞ , -4 )

Step-by-step explanation:

The standard form of O.D.E is written as :

y^{1} + p(t) = g(t)

Equation given :

(16-t^{2} )y^{1} + 9ty = 5t^{2} ,       y(-5) = 1

The first thing to do is to write the O.D.E in standard form , that is we will divide through by 16 - t^{2} , so we have

y^{1} + \frac{9ty}{16-t^{2}}=\frac{5t^{2}}{16-t^{2}}

With this , we can see that p(t) and g(t) are both continuous in the same domain. Therefore , the intervals are :

I_{1} = ( -∞ , -4 )

I_{2} = ( - 4 , 4 )

I_{3} = ( 4 , -∞ )

recall that y(−5) = 1 , then t = -5

This means that :

t = - 5 ∈ I_{1} = ( -∞ , -4 )

A. All points are translated 3 units right and 1 unit down
irga5000 [103]

Hello!

Given that the red graph is the original graph, and the blue dotted graph is the translated graph, we need to find how much units the dotted graph had translated from the original graph.

We are given the vertex of the original graph being (-2, -4). The x-value of the dotted graph, being 1, tells us that the graph translated 3 units to the right. While the y-value of the dotted graph translated 1 unit down because the original y-value was -4, and the dotted graph is at -5.

Therefore, the answer is choice A, all points are translated 3 units right and 1 unit down.
