Answer:

    X=-\frac{5}{52}

Step-by-step explanation:

-6x+5y=16x+4y=-10\\Let\\-6x+5y=-10(1)\\16x+4y=-10(2)\\8(1)+3(2):\\48x+48x+40y+12y=-80-30\\52y=-110\\y= -\frac{110}{52} =-\frac{55}{26}

replace y into (1):

-6x+5(-\frac{55}{26})=-10\\-6x=-10-5(-\frac{55}{26}  \\x= -\frac{5}{52}

Write the equation of a line passing through the points ​(2​, -4​) and ​(2​, -9​). Write the equation in​ slope-intercept form.
Norma-Jean [14]
1. find our slope: y2 - y1/ x2- x 1

-9 + 4= -5
2 - 2 = 0

m = 0

2. now we need to use our point-slope form to find our y intercept

point-slope form: y - y1 = m(x - x1)

y + 4 = 0(x - 2)

distribute:
y + 4 = 0x

3. get y by itself

y + 4 - 4 = y
0x - 4 = 0x - 4

4. write in slope-intercept form:

y = 0x - 4
OR
y = -4

Find the exact volume of the cylinder.
netineya [11]

Step-by-step explanation:

The volume of a cylinder can be found with the equation

<em><u>\pi{r}^{2}h</u></em>

So, plug in the values. The diameter of the circle is 10m, which means that the radius is 5m. The height of the cylinder is 13m.

V = π (5)^2 (13)

<u>V = 325π m^3</u>

Answer:

D. 325π m^3

Use slope formula: y2-y1/x2-x1

XZ: -5/9
YZ: 2/7
XY: -7/2

XYZ is a right triangle because two of these slopes have a product of -1.

(YZ and XY does).  We are all busy these days.

Find the compunt intrest on rs 31250 at 12 % per annum for 12 1/2 years
postnew [5]

Answer:

<h2>$128847</h2>

Step-by-step explanation:

given Principle at 31250

and rate = 12%

and time 12.5 years

the amount would be given by the equation

P(1+\frac{rate}{100})^{time}

plug in values to get

31250(1+\frac{12}{100})^{12.5}

end up with value $128847

A ball is launched from a 682.276 meter tall platform. the equation for the ball's height h at time t seconds after launch is h(
blagie [28]

The maximum height the ball achieves before landing is 682.276 meters at t = 0.

<h3>What are maxima and minima?</h3>

Maxima and minima of a function are the extreme within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.

We have a function:

h(t) = -4.9t² + 682.276

Which represents the ball's height h at time t seconds.

To find the maximum height first find the first derivative of the function and equate it to zero

h'(t) = -9.8t = 0

t = 0

Find second derivative:

h''(t) = -9.8

At t = 0; h''(0) < 0 which means at t = 0 the function will be maximum.

Maximum height at t = 0:

h(0) = 682.276 meters

Thus, the maximum height the ball achieves before landing is 682.276 meters at t = 0.
