A wooden board is leaning against a house

kobusy [5.1K]

Answer:

24.4 feet

Explanation:

Let x be the length of the wooden board as shown in the diagram.

Using trigonometry ratio, we can write

$\cos(35)=\frac{20}{x}$

$\implies0.819= \frac{20}{x}$

cross multiplying we get:

$0.819 \times x = 20$

Diving through by 0.819, we obtain

$x = 24.42$

To the nearest tenth, x=24.4 feet.

Solve the inequality 5(2h+8)<60

Bezzdna [24]

Answer and Step-by-step explanation:

$Greetings!$

$Let's~answer~your~question!$

$First, ~let's~ work~ on ~the~ left~ hand ~side~ of ~your ~inequality,~ the~ 5(2h+8)~This\\ means,~ for~ instance, ~to ~see ~if ~it ~can~ be ~simplified ~at~ all.~Multiply~ h ~and~ 2$

$The~ answer~ is~ h$

$2\times h~ evaluates~ to~ 2h$

$2\times h+8 ~evaluates~ to~ 2h+8$

$Multiply ~5~ by~ 2h+8$

$we ~multiply~ 5~ by~ each ~term ~in~ 2h+8 ~term ~by~ term~and~we~use~distributive~\\property.$

$Multiply ~5 ~and~ 2h$

$5\times2h=10h$

$Multiply~ 5 ~and ~8$

$5 \times 8 = 40$

29. The function f(t) =-16t^2 + 35 gives the height, f (in feet) of a ball t seconds after being dropped from a height of 35 fee

Nostrana [21]

The time taken for the ball to fall a distance of 10feet is 1.25secs

Given the function modeled by the height expressed as:

f(t) =-16t² + 35

In order to determine the time taken by the all to fall a distance of 10 feet, hence;

f(t) = 10

10 = -16t² + 35

-16t² = 10 - 35

-16t² = -25

-t² = -25/16

t² = 25/16

t = √25/16

t = 5/4

t = 1.25secs

Hence the time taken for the ball to fall a distance of 10feet is 1.25secs
