Write the equation for the following table: X. Y. 0 3 1 7 2 11 3 15

Vanyuwa [196]

Answer:

$y = 4x + 3$

Step-by-step explanation:

The equation of the table of values given can be written as $y = 4x + 3$ .

When x = 0,

$y = 4(0) + 3$

$y = 0 + 3 = 3$ this corresponds with what we have in the table above.

Let's try another.

When x = 2,

$y = 4(2) + 3$

$y = 8 + 3$

$y = 11$

This also corresponds with what we have in the table.

Therefore, the equation of the table given is $y = 4x + 3$ .

The measure of one angle of a right triangle is 44º more than the measure of the smallest angle. Find the measures of all

nadezda [96]

Answer:

The sum of all angles of a triangle is equal to 180 degree.
Now since it is a right angle triangle one angle is 90 degree.
And the other one given is 44 degree.
So the 3rd angle is 180 minus 90 plus 44 so it is equal to 46 degree .

A 0.02 N push accelerates a table-tennis ball along a table at 8 m/s2 north. What is the mass of the ball?

Rashid [163]

Force=0.02N=F
Acceleration=a=8m/s^2
Mass=m

According to Newton's second law

$\\ \sf\longmapsto F=ma$

$\\ \sf\longmapsto m=\dfrac{F}{a}$

$\\ \sf\longmapsto m=\dfrac{0.02}{8}$

$\\ \sf\longmapsto m=0.0025kg$

$\\ \sf\longmapsto m=2.5g$

The area of a square is 21 more than its perimeter. find the length of a side.

Evgesh-ka [11]

The formula for area of a square is s^2 so it would be 7; the perimeter would be 7+7+7+7= 28 and the area would be 7^2= 49
