Answer:

6236.78454 or 6236.78

Step-by-step explanation:

Use formula A=P(1+r)^t

A=3000(1+0.05)^180/12

*convert 15 years to moths* 180 months

A=3000(1.05)^180/12

A=3000(2.07892818 )

A=6236.78454 or 6236.78

Hope this helps ^-^

Answer:

Answer:

parabola

Step-by-step explanation:

The path followed by a ball can be modeled by a graph.

Throwing a ball is a parabola or quadratic graph.

When a ball is thrown, the path it follows can be represented by:

[tex]\mathbf{f(x) = ax^2 + bx + c}[/tex]

or

[tex]\mathbf{f(x) = a(x - h)^2 + k}[/tex]

The above equations are functions of a parabola or quadratic graph.

Hence, throwing a ball is a parabola or quadratic graph.

Answer:

10 seconds

Step-by-step explanation:

The function is

[tex]h(t)=-16t^2+\text{Initial height}[/tex]

Initial height = 1600 ft

t = Time taken

[tex]0=-16t^2+1600[/tex]

[tex]\Rightarrow -16t^2=-1600[/tex]

[tex]\Rightarrow t^2=\dfrac{1600}{16}[/tex]

Answer:  $12.80

Step-by-step explanation:

:)

Answer:

$12.80 donated money if she bikes 8 miles. solved by finding out how much money she'll get in a mile add .80+.80 and get $1.60. this is way easier to set up equation instead if doing it by half mile. equation is y=1.6(x) // y is money donated, x is $1.60

please follow me

Given:

A line passes through the points (1,-7) and (5,-25).

To find:

The y-intercept of the line.

Solution:

The line passes through the points (1-7) and (5-25). So, the equation of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-(-7)=\dfrac{-25-(-7)}{5-1}(x-1)[/tex]

[tex]y+7=\dfrac{-25+7}{4}(x-1)[/tex]

[tex]y+7=\dfrac{-18}{4}(x-1)[/tex]

[tex]y+7=-4.5(x-1)[/tex]

Subtracting 7 from both sides, we get

[tex]y=-4.5x+4.5-7[/tex]

[tex]y=-4.5x-2.5[/tex]

Putting x=0, we get

[tex]y=-4.5(0)-2.5[/tex]

[tex]y=0-2.5[/tex]

[tex]y=-2.5[/tex]

Therefore, the y-intercept of the given line is -2.5 and the vertex form of (0,-2.5).

Length of ladder (hypotenuse) = 13 ft

Step-by-step explanation:

Given:

Length of base (base) = 5 ft

Length of ladder (hypotenuse) = a

Distance between ground and ladder top (perpendicular) = a - 1

Find:

Length of ladder

Computation:

a² = 5² + (a-1)²

a² = 25 + a² - 2a + 1

2a = 26

Length of ladder (hypotenuse) = 13 ft

Answer:

Step-by-step explanation:

Write as a function.

[tex]f(x)=-3x^{2}+3[/tex]

Consider the difference quotient formula.

[tex]\frac{f(x+h)-f(x)}{h}[/tex]

Find the components of the definition.

[tex]f(x+h)=-3h^{2}-6hx-3x^{2}+3\\f(x)=-3x^{2}+3[/tex]

Plug in the components.

[tex]\frac{f(x+h)-f(x)}{h}=\frac{f(x+h)=-3h^{2}-6hx-3x^{2}+3}{h}[/tex]

Simplify

[tex]\frac{3h(-h-2x)}{h}[/tex]

The value of x rounded to the nearest whole number is 920.

A percentage is a way to describe a part of a whole such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that the number 312.8 is 34% of x.

Thus, we can write,

34% of x = 312.8

(34/100) × x = 312.8

Now, Multiply both the sides of the equation by 100,

(34/100) × x × 100 = 312.8 × 100

Now, Divide both the sides of the equation by 34,

[(34/100) × x × 100] ÷ 34 = (312.8 × 100) ÷ 38

x = (312.8 × 100)/34

x = 920

Therefore, the value of x rounded to the nearest whole number is 920.

The perimeter of the rectangle having a length of 6 units and a width of 3 units is 18 units.

The area of a rectangle is the product of its length and width.

The perimeter of a rectangle is the sum of the lengths of all the sides.

Given, The perimeter of a rectangle can be found using the expression

2l + 2w.

Also given that, the length is 6 units and the width is 3 units.

Therefore, The perimeter of this rectangle is,
