Mrs Davis invests 15,000 into a savings account that pays 7%interest for 3 years how much interest does mrs Davis earn
Answer:
3,150
Step-by-step explanation:
The amount of interest earned by the account is found using the interest formula:
I = Prt . . . . where P is the principal invested at rate r for t years
__
Using the given values, we find the interest to be ...
I = 15,000×0.07×3 = 3,150

The dimensions of a cone are shown in the figure below. What is the approximate volume, in cubic centimeters, of the cone?
Answer:
B or 415
Step-by-step explanation:
the volume of a cone is given by the formula V = (pi × r^2 × h/3)
where,
V = volume of the cone,
r = the radius of the cone,
h = the height of the cone.
so by just plugging in the values we get the answer which is 415
if you need any further guidance make sure to ask. :)
The Volume of Cone is 414.48 cm³.
What is Volume?Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.
We have,
radius = 6 cm
height = 11 cm
Now, slant height
= √r² + h²
= √11² + 6²
= √121+ 36
= √157
= 12.52 cm
Now, Volume of cone
= 1/3 πr²h
= 1/3 (3.14)(6)²(11)
= 1/3 (3.14)(36)(11)
= 414.48 cm³

What interval includes all possible values of x, where –3(6 – 2x) ≥ 4x 12? (–[infinity], –3] [–3, [infinity]) (–[infinity], 15] [15, [infinity])
The minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).
We have given inequality is
–3(6 – 2x) ≥ 4x + 12
What is the meaning of inequality?
The statement of an order relationship greater than, greater than or equal to, less than, or less than or equal to between two numbers or algebraic expressions.
[tex]-3(6 - 2x) \geq 4x + 12\\-18 + 6x \geq 4x + 12\\6x - 4x \geq 12 + 18\\2x \geq 30\\x \geq 15[/tex]
This means that the minimum of x is 15, and the most is infinity, which is the same thing as [15, ∞).

Which graph represents the function
Step-by-step explanation:
Your graph will have a vertical asymptote at x = 1, as the denominator x - 1 cannot equal zero. Therefore, f(1) is not posssible. Then, plugging in test values for the function on the left side of the asymptote...
[tex]f(-1) = \frac{2(-1)-1}{-1-1} = \frac{3}{2}\\f(0) = \frac{2(0)-1}{0-1} = 1\\f(2) = \frac{2(2)-1}{2-1} = 3\\f(3) = \frac{2(3)-1}{3-1} = \frac{5}{2}[/tex]
... you will find that your graph needs to include the following points:
[tex](-1, \frac{3}{2})\\(0, 1)\\(2, 3)\\(3, \frac{5}{2})[/tex]
So therefore, your graph must cross through the above points, and may never cross the vertical line x = 1.

Step-by-step explanation:
We know from the graph
[tex]g(x) = - \frac{1}{5} [/tex]
and
[tex]f(x) = 1[/tex]
using the given equation we can solve
[tex] - \frac{1}{5} = k - 1 \\ [/tex]
subtract 1 from both sides so that k is isolated

On his first birthday, Tomás was 30 inches tall. For the next year, he grew half an
inch each month. What equation models his height during that year, y, as a
function of the number of months, x?
Answer:
[tex]y = \frac{1}{2} x + 30[/tex]
Step-by-step explanation:
y = mx + b
y is his height during that year
x is the number of months
m is the slope or rate of change, which is 1/2 inch every month
b is the y-intercept, which is 30 inches
plug everything in then you get:
y = 1/2x + 30
Answer:
y = 1/2 x + 30
