Answer:

  • (-3, 1)
  • (5,-2)​

Step-by-step explanation:

<h3>Given a line with</h3>
  • The point (0, 1) on it
  • A positive slope
<h3>To find </h3>
  • The point from the list that is not on the same line
<h3>Solution</h3>
  • <em>Slope formula is m = (y2 - y1)/(x2 - x1)</em>

<u>Using one given point, we get the slope:</u>

  • m = (y - 1)/(x - 0)
  • m = (y - 1)/x and m > 0
<h3>Let's verify the answer choices</h3>

<u>Point (12, 3)</u>

  • m = (3- 1)/12 = 2/12 > 0, yes, on the line

<u>Point (-2,-5) </u>

  • m = (-5 - 1)/( -2) = 3 > 0, yes, on the line

<u>Point (-3, 1) </u>

  • m = (1 - 1)/(-3) = 0, no, not on the line

<u>Point (1, 15) </u>

  • m = (15 - 1)/1 = 14 > 0, yes, on the line

<u>Point (5,-2)​</u>

  • m = (-2 - 1)/5 = -3/5 < 0, no, not on the line

Mary wants to fill in a cylinder vase. At the flower store they told her that the vase should be filled 3/4 for the flowers to
Alex Ar [27]

Answer:

About 376.99 cubic inches

Step-by-step explanation:

Cylinder has a volume of:

V=\pi r^2h

Where

V is the volume

r is the radius

h is the height

We need to find the volume of the cylinder, then multiply that answer by 3/4 to get the solution to this problem. First, the full volume of the cylinder.

Given

r = 4

h = 10

So,

V=\pi r^2h\\V=\pi (4)^2 (10)\\V=502.65

Now, we multiply by 3/4:

502.65*\frac{3}{4}=376.99

Mary should be vase to 376.99 cubic inches

The center of a circle is (4, 6), and an endpoint of a diameter is (2, 5). What is the other endpoint of the diameter?
valentinak56 [21]
Consider this option:
1. if the point (4;6) is the centre of the circle and the point (2;5) is the first endpoint of its diameter, then point (4;6) is the middle point of the diameter (it means that is the middle between the 1st and the 2d endpoints of diameter).
2. using the property described above:
for x of the 2d endpoint of the diameter: x=4*2-2=6;
for y of the 2d endpoint of the diameter: y=6*2-5=7.

answer: (6;7)

A single die is rolled twice. Find the probability of rolling an
Nady [450]

Answer: 1/6

Step-by-step explanation:

A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.

Odd numbers in a die = 1, 3 and 6

Numbers greater than 4 = 5 and 6

Probability of rolling an odd number = 3/6 = 1/2

Probability of rolling a number greater than 4 = 2/6 = 1/3

We then multiply both values gotten. This will be:

= 1/2 × 1/3

= 1/6

Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.

12<br> The value of x must be greater than<br><br> a .0<br> B.1<br> C.3<br> D.7
Likurg_2 [28]

Answer:

must be greater than 7

Step-by-step explanation:

using pythagoras theorem

a^2=b^2-c^2

x^2=15^2-12^2

x^2=225-144

x^2=81

take square root both sides

√x^2=√81

x=9

and 9 is greater than 7
