Answer:

p = 7

Step-by-step explanation:

Step 1: Subtract 2p from both sides.

5p − 9 − 2p = 2p + 12 − 2p

3p−9=12

Step 2: Add 9 to both sides.

3p − 9 + 9 = 12 + 9

3p = 21

Step 3: Divide both sides by 3.

$\frac{3p}{3}$ = $\frac{21}{3\\}$

p = 7

Answer:

f(x) = -3x + 10

Step-by-step explanation:

Substitute values to find b;

y=mx+b

y=-3x+b

Replace X and Y

4=-3(2)+b

4=-6+b

Swap sides to set equal to b. Swapping causes sign change

4+6=b

10=b

base1= 158.802

 $\tan(18^o 33')= \frac{200}{base2}$

base2=596.008

the distance travelled = 596.008 - 158.802 = 438 m

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
