Slope intercept form of y+3= 1/2(x-2)?

WITCHER [35]

The slope intercept form looks like y=mx+b (m-slope, b is the y intercept)

y+3=1/2(x-2)
y=(1/2)x-(2/2)-3

y=(1/2)x-4

Rosa climbs a 16-meter tower to ride a straight water slide. After landing in the slash pool, she walks 9 meters back to the bas

erastova [34]

Answer:

The length of slide is 18.36 meters

Step-by-step explanation:

The given scenario forms a right-angled triangle where

The height of tower id perpendicular, the distance between slash pool and base of tower is base and the length of slide will be hypotenuse.

Height of tower = h = 16 meters

Distance between slash pool and base of tower = b = 9 meters

Length of slide = s = ?

As it is a right angled triangle, we can use Pythagoras theorem to find the length of slide

Pythagoras theorem states that:

$(Hypotenuse)^2 = (Base)^2+(Perpendicular)^2\\s^2 = b^2+h^2\\s^2 = (9)^2+(16)^2\\s^2 = 81+256\\s^2 = 337\\s^2 = 18.36\ meters$

Hence,

The length of slide is 18.36 meters

Teddy makes 32 fluid ounces of hot cocoa. He pours equal amounts of cocoa into 5 cups. The amount of hot cocoa in each cup will

IgorLugansk [536]

Answer: 6 and 7

Step-by-step explanation:

Since, total quantity of hot coca = $32 \text{ ounces}$

And, when he pours this quantity equal amounts of cocoa into 5 cups.

Then the quantity of hot coca in each cup

= $\frac{32}{5}\text{ ounces}$

= $6.4\text{ ounces}$

Which is between 6 ounces and 7 ounces.
