e. Segment EH is congruent to segment FG.
f. Segment GH is congruent to segment EF.

Answers

Answer: C, E, F

Step-by-step explanation: dude tbh idek but ik that it’s the right answer

The true statements are:

Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.

Given:

Triangle HEF is the image of triangle FGH after a 180-degree rotation about point KAnd Six statements

To find:

The true statements out of given sic statements.

Solution:

ΔHEF is the image of ΔFGH after a 180°rotation about point K.

This simply implies that ΔFGH is congruent to ΔHEF. As no dilation is done while rotation of the ΔFGH.

In congruent ΔFGH and ΔHEF

HF = HF (common)GH = EFFG = EH∠FGH=∠HEF∠GFH=∠EHF

Can also be written as:

⇒ ∠KFG=∠KHE

∠GHF=∠EFH

Can also be written as:

⇒ ∠GHK=∠EFK

So, from the given statements the true statements are:

Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.

what does x equal?

Answers

Answer:

16 = x

Step-by-step explanation:

Since angle B and E are congruent to each other (because triangle ABC is congruent to triangle DEC), We can set up an equation to find x.

x + 15 = 6x - 65

Add 65 and subtract x to and from both sides.

80 = 5x

Divide by x.

16 = x.

The answer is x=16 hope this helps

Answer: The y=2

Step-by-step explanation:

Anna invested $28,000 in an account paying an interest rate of 6.5% compounded daily. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $39,500?

Answers

Answer:

It will take 5.3 years to reach $39,500

Step-by-step explanation:

Compound Interest

It occurs when the interest is reinvested rather than paying it out.

Interest in the next compound period is then earned on the principal sum plus the previously accumulated interest.

The formula is:

[tex]\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

We are required to find the time needed to convert the principal P into a given final amount.

Solving the above equation for t, we get:

[tex]\displaystyle t=\frac{log(A/P)}{n\cdot log\left(1+r/n\right)}[/tex]

Anne invested P=$28,000 in an account at r=6.5%=0.065 compounded daily. There are 360 days in a year, so n=360. The final amount A=$39,500.

Substituting into the formula:

[tex]\displaystyle t=\frac{log(39,500/28,000)}{360\cdot log\left(1+0.065/360\right)}[/tex]

t=5.3 years

It will take 5.3 years to reach $39,500

If △EFG ≅ △HJK, complete each part.

Answers

Answer:

[tex] \overline{EG} \cong \overline{HK} [/tex]

[tex] \overline{HJ} \cong \overline{EF} [/tex]

[tex] \angle F \cong \angle J [/tex]

[tex] \angle H \cong \angle E [/tex]

∆FGE ≅ ∆JKH

Step-by-step explanation:

Since ∆EFG ≅ ∆HJK, therefore, the corresponding sides and angles of both ∆s are congruent.

Thus:

[tex] \overline{EG} \cong \overline{HK} [/tex]

[tex] \overline{HJ} \cong \overline{EF} [/tex]

[tex] \angle F \cong \angle J [/tex]

[tex] \angle H \cong \angle E [/tex]

∆FGE ≅ ∆JKH (take note of the arrangement of the letters or naming of each vertex of both triangles. Each vertex of in one ∆ must correspond to the vertex of the other for the ∆s to be congruent)

△EFG ≅ △HJK,

From the figure attached we can conclude that

[tex]\rm \bar {EG}[/tex] ≅ [tex]\rm \bar {HK}[/tex]

[tex]\rm \bar HJ[/tex] ≅ [tex]\rm \bar FE[/tex]

∠[tex]\rm F[/tex] ≅∠[tex]\rm J[/tex]

∠[tex]\rm H[/tex] ≅∠[tex]\rm E[/tex]

△FGE ≅ △JKH

Given that

△EFG ≅ △HJK,

Since △EFG ≅ △HJK is given hence we can conclude that corresponding sides and corresponding angles of both the triangles will be equal.

Two triangles are said to be congruent when they are of similar shape and size means all the angles of one triangle are equal to the corresponding angles of other triangle and all the sides of one triangle are equal to corresponding sides of other triangle.

From the figure attached we can conclude that

[tex]\rm \bar {EG}[/tex] ≅ [tex]\rm \bar {HK}[/tex]

[tex]\rm \bar HJ[/tex] ≅ [tex]\rm \bar FE[/tex]

∠[tex]\rm F[/tex] ≅∠[tex]\rm J[/tex]

∠[tex]\rm H[/tex] ≅∠[tex]\rm E[/tex]

Below are two inequalities and the graphs of their lines without the shading. By imagining where the shading should be, identify which point would satisfy BOTH inequalities

Answers

We want to imagine where the shading should be, and with that determine which point is a solution for both inequalities. We will see that the solution is the point (7, -8)

Interpreting inequalities:

In this case, the inqualities are:

y < -x + 1y < (-1/2)*x - 1

You can see that in both cases, y is smaller than the line, thus, for both inequalities, we must shade the part that is below the lines.

With that in mind, the region of solution will be the region that is below both lines at the same time, and that region will be the "triangle" that you can see at the middle below the horizontal axis.

Now that we know the region of solutions, we only need to see which point belongs there, from the given options the only that belongs to that region is the point (7, -8), which means that this point is a solution for both inequalities.
