Find the missing side length in the image below

Travka [436]

Let missing side be x

Using basic proportionality theorem

$\\ \sf\longmapsto \dfrac{45}{35}=\dfrac{x}{56}$

$\\ \sf\longmapsto \dfrac{9}{7}=\dfrac{x}{56}$

$\\ \sf\longmapsto 7x=9(56)$

$\\ \sf\longmapsto x=\dfrac{9(56)}{7}$

$\\ \sf\longmapsto x=72$

A hiker is lost in the woods. A search team has created a coordinate grid to represent the woods. Each unit on the grid is one s

adelina 88 [10]

Since the hiker can move in any direction, the equation that represent the area in which the hiker could be will be the equation of circle with radius r=12 and center (5,10)
The equation of a circle with radius r and center (h,k) is:
$(h-x) ^{2} +(y-k) ^{2} =r ^{2}$
The only thing we have left is replace the values to get:
$(x-5) ^{2} +(y-10) ^{2} =12 ^{2}$
$(x-5) ^{2} +(y-10) ^{2} =144$

If f(x) = 2x ^ 2 - 5 and g(x) = x ^ 2 - 4x - 8 find (f - g)(x)

choli [55]

Answer: (f-g)(x) is equivalent to f(x) - g(x)

So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3

Hope this helps.

How would I solve for this? What’s the answer?

9966 [12]

To find G of F first solve f(x) by replacing x with -7

F(x) = x^2 +6
= -7^2 +6
= 49 +6 = 55

So f(x) = 55

Now replace the X in the g(x) equation with 55

g(x) = x+8 / x

= 55+8 / 55

= 63/55

The last choice is the correct answer.

Jacky spent 53% of all her money to buy a computer game. How much did the game cost, if Jacky had $120 before buying the game?

Keith_Richards [23]

The game cost 63.6$, because 53% of 120 is 63.6
