simplyfy 5x + 7x - 3 + 10x - 5x - 20

Answer:

The time required to get  a total amount of $ 12,600.00  from compound interest on a principal of $9000  at an interest rate of 4.75% per year  and compounded 4 times per year  is 7.1 years.

Step-by-step explanation:

Given

Principle P = 9000 dollars

Rate r = 4.75% = 0.0475

Total Amount A = 12600 dollars

compounded quarterly n = 4

To determine:

Time t = ?

Using the equation

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

solving the equation for 't'

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(12,600.00/9,000.00) / ( 4 × [ln(1 + 0.011875/4)] )

t = 7.1 years

Therefore, the time required to get  a total amount of $ 12,600.00  from compound interest on a principal of $9000  at an interest rate of 4.75% per year  and compounded 4 times per year  is 7.1 years.

Given:

The function are

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

[tex]g(x)=\sqrt{x}[/tex]

To find:

The value of [tex](f\circ g)(1)[/tex].

Solution:

We have,

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

[tex]g(x)=\sqrt{x}[/tex]

We need to find the value of [tex](f\circ g)(1)[/tex].

[tex](f\circ g)(1)=f(g(1))[/tex]            [tex][\because (f\circ g)(x)=f(g(x))][/tex]

[tex](f\circ g)(1)=f(\sqrt{1})[/tex]            [tex][\because g(x)=\sqrt{x}][/tex]

[tex](f\circ g)(1)=f(1)[/tex]      

[tex](f\circ g)(1)=(1)^2-1[/tex]                  [tex][\because f(x)=x^2-1][/tex]

[tex](f\circ g)(1)=1-1[/tex]      

[tex](f\circ g)(1)=0[/tex]      

The value of [tex](f\circ g)(1)[/tex] is 0.

Therefore, the correct option is A.

Answer:

y = 4x -3

Step-by-step explanation:

Here, we want to get the equation of the blue line

As we can see, the y-intercept is -3

So we have the equation as;

y = mx -3

To get the value of m which is the slope , we check for any point on the line

That would be;

(1,1)

Let us have this substituted;

1 = m(1) - 3

1 = m -3

m = 1 + 3

m = 4

so the equation of the straight line is;

y = 4x -3

Answer:

Step-by-step explanation:

3(2x + 2) - 3x = 6 + 3x

6x + 6 - 3x = 6 + 3x

6x - 3x = 3x

3x + 6 = 6 + 3x

the answer would be

Answer:

The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]

Step-by-step explanation:

Intercepts of a Function

Given a function y=f(x), the intercepts with the x-axis, if any, can be found by solving the equation:

y = f(x) = 0

The intercepts with the y-axis can be found by calculating

f(0)

We are given the function

y - 4x = 1

To find the x-intercepts, set y=0:

0 - 4x = 1

Solving:

[tex]x = -\frac{1}{4}[/tex]

For x=0:

y - 4*0 = 1

y = 1

The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]

Answer:

first three terms are 3, 6, 9 and the 10th one is 30

Step-by-step explanation:

Answer:

3, 12, 27 and 300

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the n th term formula

3(1)² = 3 × 1 = 3

3(2)² = 3 × 4 = 12

3(3)² = 3 × 9 = 27

The first 3 terms are 3, 12, 27

Substitute n = 10 into formula for 10 th term

3(10)² = 3 × 100 = 300

Answer: 2520

Step-by-step explanation:

Given: Number of people supported the visiting team = 882

Let x = Total number of people at the game.

As per given,

35% of x = 882    [35% were supporting the visiting team]

[tex]\Rightarrow\ 0.35x=882\\\\\Rightarrow\ x=\dfrac{882}{0.35}\\\\\Rightarrow\ x= 2520[/tex]

Hence, the total number of people at the game = 2520 .

Answer:

Hichman will walk faster.

Step-by-step explanation:

Hichman walks 84 feet in 7 seconds and Brittany walks 110 feet in 20 Second.

We need to say who walks faster.

For Hichman,

Distance, d = 84 feet and time, t = 7 s

Speed,

[tex]v_H=\dfrac{d}{t}\\\\v_H=\dfrac{84}{7}\\\\=12\ ft/s[/tex]

For Brittany,

Distance, d = 110 feet and time, t = 20 s

Speed,

[tex]v_B=\dfrac{d}{t}\\\\v_B=\dfrac{110}{20}\\\\=5.5\ ft/s[/tex]

It can be seen that speed of Hichman is 12 ft/s and the speed of Brittany is 5.5 ft/s. It is clear that the speed of Hichman is more than that of Brittany. Hence, Hichman will walk faster.

Answer:

the surface are of a rectangle box of 5cm long, 3cm wide and 4cm wide is 94cm²

The measure of two supplementary angles are 82° and 98°.

Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.

Given that, an angle measures 16° more than the measure of its supplementary angle.

Let the measure of one angle be x.

Then, the other angle is x+16°.

Now, x+x+16°=180°

2x+16°=180°

2x=164°

x=82°

So, x+16°=82+16°=98°

Therefore, the measure of two supplementary angles are 82° and 98°.

-5 sorry if it's wrong. I tried.

Answer:

-5

Step-by-step explanation:

Step-by-step explanation:

We only know 1 side, and that is the width of 4. We only have the diagonals at our side. Half of the diagonal is 5. As a result, the diagonal is 10. I want you to imagine a triangle that has a base of 4 and a hypotenuse of 10. Use the Pythagorean Theorem to find b, or the height.

a² + b² = c²

4² + b² = 10²

16 + b² = 100

100 - 16 = 84

b² = 84

b = √84

b ≈ 9.165

Now we know the length of the rectangle, which is about 9.165. Multiply that by 4 to get the area.

9.165 * 4

36 + 0.4 + 0.24 + 0.020

36.4 + 0.24 + 0.02

36.64 + 0.02

36.66 u²

The area of rectangle RSTU is about 36.66 units squared.
