Which equation represents the line that is parallel to segment RS in the triangle below and passes through point T?

mestny [16]

Answer:

$y = \frac{1}{2}x +4$

Step-by-step explanation:

Given:

$R = (0,0)$

$S= (8,4)$

$T = (-2,3)$

First, we have that the line is parallel to RS.

This means that the line has the same slope as RS and the slope of RS is calculated as follows:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{4-0}{8-0}$

$m = \frac{4}{8}$

$m = \frac{1}{2}$

So, the line has a slope of $m = \frac{1}{2}$

Next, we have that the line passes through $T = (-2,3)$ .

The equation of the line is then calculated using the following formula

$y - y_1 = m(x - x_1)$

$y - 3 = \frac{1}{2}(x - (-2))$

$y - 3 = \frac{1}{2}(x +2)$

Open bracket

$y - 3 = \frac{1}{2}x +1$

Make y the subject

$y = \frac{1}{2}x +1+3$

$y = \frac{1}{2}x +4$

How many of the numbers from the set $\{1,\ 2,\ 3,\ldots,\ 50\}$ have a perfect square factor other than one?

Novay_Z [31]

Answer:

2^2 ( 1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44,48

3^2(1,2,3, 5) = 9, 18, 27, 45

5^2(1, 2) = 25, 50

7^2 = 49

I need help with this question

postnew [5]

Answer:

61 cm for each book shelf.

Step-by-step explanation:

First it gives you the width of the boxes so you add them together

132 + 108 + 94 = 334

so 334 cm has already been used out of 456 cm.

Next you will 456 - 334 = 122 cm left over

if they are building 2 book cases you with take what cm's you have left and divide it by 2

122 / 2 = 61

So that means each book case will be 61 cm's wide

3 sinx + 4 cosx = 5

vagabundo [1.1K]

<span>3sinx+4cosx=5
=> 3/5 sinx +4/5 cosx = 1
let cosA=3/5 => sinA=4/5
=> cosAsinx + sinAcosx = 1
=> sin(x+A) = 1
Now,
4sinx - 3cosx
= 5(4/5sinx - 3/5 cosx) [multipying numerator and denominator by 5]
= 5(sinAsinx - cosAcosx)
= -5{cos(x+A)} = -5[root{1-(sin(x+A)^2)}] = -5 x 0 = 0 Ans 0

TRICK: if asinx+bcosx is given then multiply numerator and denominator by root(a^2 +b^2)
this method is useful in many questions </span>

Is 400% of 5 less than 10, greater than 10 but less than 100, or greater than 100?

Kryger [21]

Answer:

400% of 5 = 5 x 400/100 = 20.

20 > 10 and 20 < 100

Hope this helps!
