Please please help me!!!

Value of h please help me, I don't understand

Greeley [361]

Answer: h = 14.1 ft

Step-by-step explanation:

The given triangle is an isosceles right angle triangle because the two sides or legs of the triangle are equal. To determine h, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Hypotenuse = 20ft

opposite side = adjacent side = h feet

Therefore

20² = h² + h²

400 = 2h²

h² = 400/2 = 200

Taking square root of both sides, it becomes

h = √200

h = 14.1 ft

Liza y Abby planean extender sus mantas en un parque para un picnic con sus amigos. El parque está lleno de gente, así que extie

Margarita [4]

Answer:

Step-by-step explanation:

The question in English is basically find the area of the pink and blue area shown. The image is attached. This is Liza and Abby's blanket spread and we want the area of the whole shown.

Solution:

We want area of pink rectangle PLUS the blue region, which is a sum of lower rectangle and top triangle (if we cut it in this way).

First, area of pink rectangle:

Area = length * height

Area = 5 * 5.7

Area = 28.5

Now, the blue region, if broken down, lower portion is rectangle and upper portion is a triangle (we DISREGARD the overlapping region, of course!)

Lower Rectangle Area = length * height = 4 * 2 = 8

Upper triangle Area = 0.5 * base * height = 0.5 (4) * (6-2) = 0.5 * 4 * 4 = 8

So, blue region area = 8 + 8 = 16

Total Area = 28.5 + 16 = 44.5 sq. ft.

PLEASE HELP

kolbaska11 [484]

Answer:

a) P(x) = 32000*1.04^x
b) $37435
c) During year 7

Step-by-step explanation:

Given

Initial pay = $32000
Increase rate = 4%

a. Formula

P(x) = 32000*1.04^x

b. Year 5 is after 4 years, so we are looking for the value of P(4)

P(4) = $32000*1.04^4 = $37435

c. P(x) = 40000, x = ?

40000 = 32000*1.04^x
1.04^x = 40000/32000
1.04^x = 1.25
log 1.04^x = log 1.25
x = log 1.25 / log 1.04
x = 5.69, this is 6 years after

The required number of the years is 6 + 1 = 7
