The ladder makes an angle 30 degrees with the ground

Data;

Length of the ladder (hypothenuse) = 30 ft

height of the wall (opposite) = 15 ft

When the ladder reclines on the wall, it forms a right-angle triangle and we can solve it.

Using SOHCAHTOA,

We have the value of hypothenuse and opposite and we can use the sine angle of this triangle.

The ladder makes an angle 30 degrees with the ground.

A fully functioning forest has a great capacity to regenerate. But exhaustive hunting of tropical rainforest wildlifecan reduce those species necessary to forest continuance and regeneration. For example, in Central Africa, theloss of species like gorillas, chimps, and elephants undercuts the seed dispersal and slows the recovery.

Step-by-step explanation:

The amount of money does Liam need to put in the simple interest account to earn  $750 in interest, is $6250.

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.

The formula for the simple interest can be given as,

[tex]I=\dfrac{Prt}{100}[/tex]

Here, (I) is the interest amount earned on the principal amount of (P) with the rate of (r) in the time period of (t).

Liam wants to put some money in a simple interest account. He pays R=6% interest annually for t=2 years. Liam would like to earn I=$750 in interest.

Put the values in the formula,

[tex]750=\dfrac{P\times6\times2}{100}\\P=\dfrac{750\times100}{6\times2}\\P=6250[/tex]

Thus, the amount of money does Liam need to put in the simple interest account to earn  $750 in interest, is $6250.

Answer:

[-5, 4) ∪ (4, ∞)

Step-by-step explanation:

Given functions:

[tex]f(x)=\dfrac{1}{x-3}[/tex]

[tex]g(x)=\sqrt{x+5}[/tex]

Composite function:

[tex]\begin{aligned}(f\:o\:g)(x)&=f[g(x)]\\ & =\dfrac{1}{\sqrt{x+5}-3} \end{aligned}[/tex]

Domain: input values (x-values)

For [tex](f\:o\:g)(x)[/tex] to be defined:

[tex]x+5\geq 0 \implies x\geq -5[/tex]

[tex]\sqrt{x+5}\neq 3 \implies x\neq 4[/tex]

Therefore, [tex]-5\leq x < 4[/tex]  and  [tex]x > 4[/tex]

Answer:

[tex]408cmx^{2}[/tex]

Step-by-step explanation:

A=2(wl+hl+hw)=2·(2·6+24·6+24·2)= 408cm²

length= 6

width= 2

height= 24

the area if the box.

[tex]a = lwh[/tex]

[tex]a = 2(wl + hl + hw)[/tex]

[tex]a = 2 \times (2.6 + 24.6 \times + 24.2)[/tex]

[tex]a = 408 {cm}^{2} [/tex]

therefore, the area of the box is 408 square centimeters.

a. The least amount as indicated in the box plot is: 10

b. Median amount of snowfall is: 20

c. Data is concentrated at the third quartile

The median of a data in a box plot is the value indicated by the vertical line that divides the box.

a. The least amount is the minimum value which is at the extreme end of the whisker to your left = 10

b. Median amount of snowfall is the value indicated by the vertical line = 20

c. The largest section is the third quarter, so the data is most concentrated within the third quarter.

Answer:

x = 6.40

Step-by-step explanation:

The formula to find the area of the rectangle is :

Area = Length × Width

Given that,

Area ⇒ 50

Length ⇒ ( 2x - 5 )

Width ⇒ x

So now we can write an expression like this.

Area = Length × Width

50  = x ( 2x - 5 )

And now we can solve for x.

Let us solve now by using the completing square method.

x ( 2x - 5 ) = 50

2x² - 5x = 50

First divide the whole equation by 2.

x² - 2.5 = 25

x² - 2.5 + 1.5625 = 25 + 1.5625

( x - 1.25 )² = 26.5625

x - 1.25 = ±√26.5625

x  - 1.25 = ±5.1538

So,

x = + 5.1538 + 1.25                           or        x = - 5.1538 + 1.25

x = 6.40                                                       x = -3.90

As we cannot get a negative number as a value for length,

x = 6.40

(74 + 67 +73 +x)  = 288

shift the first three terms on the right side

x = 288 -74 -67 -73 =  74

Answer:

x^2 +3x -4 = 0  --> (x +4)(x -1) = 0

Step-by-step explanation:

Let's find A and B such that

A*B = - 4    and  A+B = 3

Numbers are:

A = +4  and  B = -1

The factoring equation is y = (x + A)(x + B)

In this specific case: y = (x +4)(x -1)

Solutions to the quadratic equation require

y = (x +4)(x -1) = 0

and hence

x +4 = 0  --> x = -4

x - 1 = 0 -->  x= +1
