14. height = volume/ ( length x width)

Height = 224/ ( 2x8)

Height = 224/16

Height = 14 inches.

15. height = volume/ area of the top(circle)

Area of top = pix r^2 = 3.14 x 4 = 12.56 square inches.

Height = 62.8/12.56 = 5 inches

16. Volume/ height = area of top(circle)

169.56/ 6 = 28.26 square inches

Area = pi x r^2

28.26 = 3.14 x r^2

Divide both sides by 3.14

R^2 = 28.26/3.14 = 9

Take the square root of both sides

R = sqrt(9)

R = 3

Radius = 3 inches

For what values of y:

Whitepunk [10]

Answer:

$y > \frac{3}{17}$

Step-by-step explanation:

To solve this problem, simply set the binomial, $5y - 1$ as greater than $\frac{3y - 1}{4}$ , and solve for the value of y as you would solve an equation.

Thus:

$5y - 1 > \frac{3y - 1}{4}$

Multiply both sides by 4

$4(5y - 1) > \frac{3y - 1}{4}*4$

$4*5y - 4*1 > 3y - 1$

$20y - 4 > 3y - 1$

Subtract 3y from both sides

$20y - 4 - 3y > 3y - 1 - 3y$

$17y - 4 > -1$

Add 4 to both sides

$17y - 4 + 4 > -1 + 4$

$17y > 3$

Divide both sides by 17

$\frac{17y}{17} > \frac{3}{17}$

$y > \frac{3}{17}$

Therefore, the value of y that will make the binomial $5y - 1$ greater than $\frac{3y - 1}{4}$ is $y > \frac{3}{17}$ .

Y = ax2 + c Axis of symmetry:

Mrac [35]

Answer: Hope this helps you solve the problem if you need better examples or a direct answer just reply ヾ(•ω•`)o

Step-by-step explanation: Rewrite the equation as ax2 +bx+ c = y a x 2 + b x + c = y. Move y to the left side of the equation by subtracting it from both sides. Use the quadratic formula to find the solutions. Or you can Problem 1 0 Graph y = x2 the first thing we need to do is to remember the x and y table we used to make for y = mx + b. We will do this on the below table always using the numbers -2, -1, 0, 1, 2.

13. Find the equations of the straight lines which passes

ipn [44]

9514 1404 393

Answer:

y = 1/2x +2
y = -2x +7

Step-by-step explanation:

The slope of a line is the tangent of the angle it makes with the x-axis. The given line has a slope of -1/3, so the lines we want will have slopes of ...

m1 = tan(arctan(-1/3) +45°) = 0.5 . . . . . using a calculator

m2 = tan(arctan(-1/3) -45°) = -2

Of course, these two lines are perpendicular to each other, so their slopes will have a product of -1: (0.5)(-2) = -1.

We can use the point-slope form of the equation for a line to write the desired equations:

y = m(x -h) +k . . . . . line with slope m through point (h, k)

Line 1:

y = 1/2(x -2) +3

y = 1/2x +2

Line 2:

y = -2(x -2) +3

y = -2x +7
