Yesterday, there were 80 problems assigned for homework. Harry did 20% of them correctly. How many problems did Harry get right?

Your answer is:

V(n) = 30(0.95)^n

Why?

Well here is why!

Rate of decrease = 5%

Period, n = 10 days

Initial stock price = $30

Value of share price as a function of n:

Value, V(n)

Initial price = A

V(n) = Initial price(1 - rate)^n

V(n) = 30(1 - 0.05)^n

V(n) = 30(0.95)^n

Answer:

10.4

Step-by-step explanation:

So let's do the basic, adding. 5 kilometers on Saturday and 4 on part of Sunday. That's 9. So let's save that. Now for the meters. We know that there are 1000 meters in a kilometer. So add up 600 and 800. That gives you 1400 meters total. Now if we divide 1400 by 1000, we get 1.4. So that is how many kilometers he rode on Friday and and the other part of Sunday. SO now we just add everthing up. 9km+1.4km = 10.4, your answer

Answer:

2.34 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle at the centre (θ) = 34°

Radius (r) = 4 cm

Length of chord (C) =?

The length of the chord can be obtained as follow:

C = 2rSine(θ/2)

C = 2 × 4 × Sine(34/2)

C = 8 × Sine 17

C = 8 × 0.2924

C = 2.34 cm

Therefore, the lenght of the chord is 2.34 cm.

Answer:

(7+5.5)m + 5.5(2)

Step-by-step explanation:

Given:

Equation;

7m + 5.5(2+m)

Find:

Equivalent way

Computation:

7m + 5.5(2+m)

7m + 11 + 5.5 m

12.5m + 11

Or

(7+5.5)m + 5.5(2)

Answer:

26

Step-by-step explanation:

first, substitute the value for x into the expression. since x = 6, you will be plugging in 6 for x.

4x + 2 ⇒ 4(6) + 2

simplify the expression, starting with 4 · 6.

4(6) + 2 ⇒ 24 + 2

then add 24 + 2.

24 + 2 ⇒ 26

aaaand your answer is 26! hope this helps. have a lovely day! <3

Question 3

The triangle is right isosceles (45°)

The legs have equal length

Question 4

The figure is a square

The angle between sides 24 and 24 is the right angle

Answer:

The circumference of the circle is about 166.42 cm.

The area of the circle is about 2205.07 cm².

Step-by-step explanation:

Diameter = 53 cm

Radius = r = 53cm/2 = 26.5 cm

π = 3.14

Circumference = C = 2 π r

C = 2(3.14)(26.5cm) = 166.42cm

The circumference of the circle is about 166.42cm.

Area = A = π r²

A = (3.14)(26.5cm)² = 2205.07 cm²

The area of the circle is about 2205.07 cm².

Answer:  D) 10

============================================================

Explanation:

I'm assuming points M and N are midpoints of segments FD and FE respectively. If that's the case, then segment DE is twice as long compared to segment MN. We consider MN to be a midsegment.

So,

DE = 2*(MN)

3x-2 = 2*(x+4)

3x-2 = 2x+8

3x-2x = 8+2

x = 10

Step-by-step explanation:

you have to have some number for someone to solve it

The statement that could be false on the interval is if x is greater than π/2

Given the function g(x)=√ 1−sin2x

We are to get the value of x that will make the function not exist. For the function not to exist, hence:

sin2x> 1

Solve the expression for x

2x > arcsin(1)

2x > π

x > π/2

This shows that the statement that could be false on the interval is if x is greater than π/2

Answer:

14√2

Step-by-step explanation:

This is a 45-45-90 triangle

Because both of the angles are the same all sides, but the hypotonouse are the same

this means that the other length is 14 too

we can use a²+b²=c² to solve

14²+14²=c²

=

392=c²

√392=c

√392=14√2

Answer:

[tex]Rate = 9(t+1)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 9x^2 - 2[/tex]

[tex]Interval = [1,t][/tex]

Required

Determine the average rate of change

This is calculated using:

[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex][a,b] = [1,t][/tex]

So, we have:

[tex]Rate = \frac{f(t) - f(1)}{t - 1}[/tex]

Solve for f(t) and f(1)

[tex]f(t) = 9t^2 - 2[/tex]

[tex]f(1) = 9*1^2 - 2[/tex]

[tex]f(1) = 9 - 2[/tex]

[tex]f(1) = 7[/tex]

So, we have:

[tex]Rate = \frac{9t^2 - 2 - 7}{t - 1}[/tex]

[tex]Rate = \frac{9t^2 - 9}{t - 1}[/tex]

Factorize:

[tex]Rate = \frac{9(t^2 - 1)}{t - 1}[/tex]

Apply difference of two squares

[tex]Rate = \frac{9(t- 1)(t+1)}{t - 1}[/tex]

[tex]Rate = 9(t+1)[/tex]

Answer:

[tex]r=-3[/tex]

Step-by-step explanation:

The line that passes through the two points (6, -23) and (11, r) has a slope of 4.

We want to determine the missing value of r.

We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:

[tex]\displaystyle \frac{r-(-23)}{11-6}=4[/tex]

Simplify and evaluate:

[tex]\displaystyle \frac{r+23}{5}=4[/tex]

Multiply both sides by 5:

[tex]r+23=20[/tex]

Therefore:

[tex]r=-3[/tex]
