Answer: The angle of elevation of the sun [tex]=64.40^{\circ}[/tex]

Step-by-step explanation:

According to the trigonometry,

In a right triangle,

[tex]tan A=\dfrac{Perpendicular}{Base}[/tex]

Let angle of elevation of the sun = x

From the given figure, Perpendicular = 286 feet

Base = 137 feet

[tex]\tan x =\dfrac{286}{137}\\\\ \tan x = 2.0876\\\\ x=\tan^{-1}(2.0876)\\\\ x=64.40^{\circ}[/tex]

The angle of elevation of the sun [tex]=64.40^{\circ}[/tex]

Answer:

Zeros are x = 1.5, -2.5

Step-by-step explanation:

Given function is,

F(x) = 4x² + 4x - 15

      = 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]

F(x) = 4(x² + 2.5x - 1.5x - 3.75)

      = 4[x(x + 2.5) - 1.5(x + 2.5)]

      = 4(x - 1.5)(x + 2.5)

For 'x' intercepts,

f(x) = 0

4(x - 1.5)(x + 2.5) = 0

x = 1.5, -2.5

Therefore, zeros of the given function are x = 1.5, -2.5.

Answer:

The zeroes are: -3 and -2

Step-by-step explanation:

f(x) = x² + 5x + 6

This is the in the format...

ax² + bx + c

To find the zeroes of a function, you must find what two numbers that add to B but multiply to C. In this case, you have to find two numbers that add to 5 but multiply to 6.

The two numbers are...

3 + 2 = 5 (This is correct because the two numbers add are equal to B)

3 x 2 = 6 (This is correct because the two numbers multiplied together are equal to C)

You then know that you have ( x + 3 ) and ( x + 2 )

Please do not get confused, the answers ARE NOT 3 and 2. You have to set the zeroes equal to 0.

Here's what I mean by that...

x + 3 = 0

Subtract 3 on both sides...

x = -3

The other zero...

x + 2 = 0

Subtract 2 on both sides...

x = -2

Your answers are x = -2 and x = -3, make sure you always set your answers to zero.

Hope this helps!

=========================================================

Explanation:

Notice how EC = 5 doubles to BC = 5+5 = 10

So the larger quadrilateral (ABCD) has side lengths that are exactly twice as long compared to the smaller quadrilateral's sides. We can say the scale factor is 2.

This must mean that side FG = 4 doubles to 4*2 = 8, which is the length of side AD. So that's how we get y = 8.

-----------------------------------

Extra info:

Length of AD, y = 8

Two quadrilaterals are similar if their corresponding angles are equal and also their corresponding sides must be proportional.

Given,

EC = 5

FG = 4

BE = 5

AD = y

ABCD ~ FECG,

then ratio of the corresponding sides will be equal.

BC/AD = EC/FG

(BE + EC)/AD = EC/FG

(5 + 5)/y = 5/4

10/y = 5/4

5y = 40

y = 40/5

y = 8.

Hence, 8 is value of y that is length of AD.

Answer:

The y-intercept of the function and the vertex of the function would change. (III and IV) This answer doesn't seem to be in the answer list (but there is proof for the answers below), though.

Step-by-step explanation:

(Notice that [tex]2f(x-4) = 2(x-4)^2.[/tex])

The domain of the function won't change because quadratics can all take all numbers as their input (which, by definition, is the domain of a function).

The range of the function won't change either, because we have just moved the function with 4 to the right (by substituting [tex]x[/tex] with [tex]x-4[/tex]) and multiplied the graph with respect to the y-axis by 2. The range will stay as all non-negative real numbers.

The y-intercept of the function will change, because for [tex]f(x)=x^2[/tex] it is [tex]y=0[/tex], while for [tex]y=2(x-4)^2[/tex] substituting [tex]x=0[/tex] doesn't give [tex]y=0[/tex]. (Instead, it gives [tex]y=32[/tex].)

The vertex of the function will change, because we have moved the function with 4 to the right and multiplied the graph with respect to the y-axis by 2: the vertex will have at the very least moved to the right.

Answer:

14.940306992% or 15%

Step-by-step explanation:

To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.

$ 175.90 - $ 149.62 = $26.28

Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.

$26.28 / $175.90

= 0.14940306992

Finally, multiply by 100 and round up to reach a percentage.

Answer:

n+5

Step-by-step explanation:

Answer:

n + 5 or 5 + n

Step-by-step explanation:

add 5 to n, tanya's current age, to find how old she'll be in 5 years.

since the variable n is not defined, the answer cannot be simplified further than n + 5.

if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.

Answer:

x = 54

Step-by-step explanation:

These are corresponding angles assuming that both transversals are parallel. Since these angles are corresponding, they must be congruent which means that both measures are the same.

Now the basic algebra can be done to find x:

(x + 12)° = 66°

(x)° = (66 – 12)°

(x)° = (54)°

x = 54

Answer:

6 ; 24 ; 5.4 ; 24.6

Step-by-step explanation:

Given that:

Number of samples from each high school = 30

Proportion of students from high school A = 20%

Proportion of students from high school B = 18%

Number of sample A ; n(A) = 30

Proportion of sample A ; p(A) = 0.20

Number of sample B ; n(B) = 30

Proportion of sample B ; p(B) = 0.18

1.)

n(A).p(A) = 30 * 0.20 = 6

2.)

n(A). (1 - p(A))

30 * (1 - 0.20)

30 * 0.8 = 24

3.)

n(B).p(B) = 30 * 0.18 = 5.4

4.)

n(B). (1 - p(B))

30 * (1 - 0.18)

30 * 0.82

= 24.6
