Answer:

Hi. so I don't have the answers but usually if you find the name of the website your homework is from (if should be at the bottom of the page) online you can also find the answers for it. Just letting you know for this homework and future references.

Step-by-step explanation:

If the teacher asks for you to show your work the website might not show you step by step but you can just say you did it on a separate page. hope this helps!

Answer:

  • h(x) = 1/2 |x - 1|  -  2
  • h(x) = - (x + 2)²  +  3

Step-by-step explanation:

  • <em>See attached</em>

You need to recognize the parent function by looking at the graph. Then you need to find out how different is the graph from the parent function and finally work out the equation of the graph considering the transformations.

4)

<u>The parent function is the absolute value function:</u>

  • h(x) = |x|

Its vertex is at the origin. We see the vertex has shifted and also the slope has changed.

We can find the slope easily, the ratio of rise to run is 1/2

<u>The function becomes:</u>

  • h(x) = 1/2 |x|

Now considering the translation. We see the vertex has coordinate of (1, -2)

It means the graph has shifted 1 unit right and 2 units down.

<u>The shift right  is shown as:</u>

  • h(x) = 1/2 |x - 1|

<u>and adding the shift down:</u>

  • h(x) = 1/2|x - 1| - 2

This is our final equation.

5)

Parabola is the graph of the quadratic function.

<u>The vertex form of the function is:</u>

  • h(x) = a(x - h)² + k, where (h, k) is the vertex

<u>Now, we see it is opening down and the vertex is at (-2, 3):</u>

  • h(x) = a(x - (-2))² + 3 = a(x + 2)² + 3

<u>To find the value of a we can use a point on the graph. Let's use point (0, -1):</u>

  • -1 = a(0 + 2)² + 3
  • -1 = 4a + 3
  • 4a = -4
  • a = -1

<u>The function is:</u>

  • h(x) = - (x + 2)² + 3

Suppose you invest 1600 at annual interest rate of 7.9% compounded cont how much will u have after 10yrs
frez [133]

Answer:

B. $3525.43

Step-by-step explanation:  

We will use continuously compound interest formula to solve our problem.

A=P*e^{rT}      

A= Amount after T years.

P= Principal amount.

r= Interest rate (in decimal form).

e= The mathematical constant e.

T= Time in years.

First of all we will convert our interest rate in decimal form.

7.9\text{ Percent}=\frac{7.9}{100}=0.079

Now let us substitute our given values in above formula.

A=1600*e^{0.079*10}

A=1600*e^{0.79}

A=1600*2.2033964262559365

A=3525.4342820094984\approx 3525.43

Therefore, we will get an amount of $3525.43 after 10 years and option B is the correct choice.

Hi guys . pls help me with this​
daser333 [38]

Step-by-step explanation:

The upstream speed is S / t₁, and the downstream speed is S / t₂.

If we say f is the speed of the fish in calm water, and r is the speed of the river, then:

f − r = S / t₁

f + r = S / t₂

If we say T is the time it takes to cross the river, then the speed perpendicular to the river is ℓ/T, the speed parallel to the river is r, and the overall speed is f.

Using Pythagorean theorem:

f² = (ℓ/T)² + r²

f² − r² = (ℓ/T)²

(f − r) (f + r) = (ℓ/T)²

(S / t₁) (S / t₂) = (ℓ/T)²

S² / (t₁ t₂) = (ℓ/T)²

(t₁ t₂) / S² = (T/ℓ)²

√(t₁ t₂) / S = T/ℓ

T = ℓ√(t₁ t₂) / S
