Answer:

6 dollars

Step-by-step explanation:

first work out how much of a pound he wanted to buy

3/5 of a pound

divide one pound by five then time that by three

1÷5=0.2

0.2×3=0.6

so 0.6 pounds

now if one pound is 10 dollars

what will 0.6 pounds be?

find how much pounds you get for one dollar

1÷10=0.1

so one dollar buys 0.1 pounds

so times by 6 to get 0.6 pounds for 6 dollars

Step-by-step explanation:

Glass beads cost $10 per pound

He didn't buy upto one pound, just 3/5

$cost \: = \frac{3}{5} \times 10 \\ = 6$

He spent $6

Given:

Given that the graph of the quadratic function.

We need to determine the value of a in the function's equation.

Value of a:

The value of a can be determined using the formula,

$y=a(x-h)^2+k$

where (h,k) is the vertex and a is a constant.

From the graph, it is obvious, that the vertex of the parabola is (0,9).

Thus, substituting the vertex (h,k) = (0,9) in the above formula, we get;

$y=a(x-0)^2+9$

$y=ax^2+9$ -------- (1)

Let us substitute any one of the coordinate that the graph passes through to determine the value of a.

Let us substitute the point (3,0) in the equation (1), we have;

$0=a(3)^2+9$

$0=9a+9$

$-9=9a$

$-1=a$

Thus, the value of a is -1.

Hence, Option B is the correct answer.

Question

rodikova [14]

Answer:

$Volume = 11488.21$

$Area = 2461.76$

Step-by-step explanation:

Given

$Radius, r = 14\ in$

Shape: Sphere

Solving (a): The Volume

This is calculated as:

$Volume = \frac{4}{3}\pi r^3$

Take $\pi$ as 3.14 and substitute 14 for r

$Volume = \frac{4}{3} * 3.14 * 14^3$

$Volume = \frac{4}{3} * 3.14 * 2744$

$Volume = \frac{4 * 3.14 * 2744}{3}$

$Volume = \frac{34464.64}{3}$

$Volume = 11488.21$

Solving (b): The Surface Area

This is calculated as follows:

$Area = 4\pi r^2$

Take $\pi$ as 3.14 and substitute 14 for r

$Area = 4 * 3.14 * 14^2$

$Area = 4 * 3.14 * 196$

$Area = 2461.76$

Write the point-slope form of the line that passes through (6,1) and is parallel to a line with a slope of -3 include all of you

ycow [4]

Answer:

The point-slope form of the line that passes through (6,1) and is parallel to a line with a slope of -3 is 3x + y – 19 = 0

Solution:

The point slope form of the line that passes through the points $\left(x_{1} y_{1}\right)$ and parallel to the line with slope “m” is given as

$y - y_{1} = m\left(x - x_{1}\right)$ --- eqn 1

Where “m” is the slope of the line. $x_{1} \text { and } y_{1}$ are the points that passes through the line.

From question, given that slope “m” = -3

Given that the line passes through the points (6,1).Hence we get $x_{1} = 6 ; y_{1} = 1$

By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope -3 can be found out.

y – 1 = -3(x – 6)

y – 1 = -3x +18

On rearranging the terms, we get

3x + y -1 – 18 = 0

3x + y – 19 = 0

Hence the point slope form of given line is 3x + y – 19 = 0
