Answer:

50

Step-by-step explanation:

if you dividde 24 by 20 you get 1.2 if you plug 1.2 into an inverse tangent calculator you get 50.19

The angle of elevation to the nearest degree of Juan's line of sight to the top of the tree is 50.19.

Trigonometric functions are the functions that include trigonometric identities such as sine, cosine, tangents, secant, and, cot.

Juan is looking up to the top of a tree that is 31 feet tall. He is standing 20 feet from the tree.

The angle of elevation to the nearest degree of Juan's line of sight to the top of the tree.

Tan Ф = perpendicular/ base

          = 24/ 20

Tan Ф  = 1.2

Ф  =[tex]( Tan )^{-1}1.2[/tex]

Ф  = 50.19

Answer:

Step-by-step explanation:

first step

let's create the equation word problem

let's solve

let my mother's and sister's age be x and y respectively

according to the first condition,x=4y....(I)

according to the 2nd condition,x+5=2(y+5×2).....(ii)

so the system of linear equations is

x=4y

x+5=2(y+5×2)

gets from the second equation

x+5=2(y+10)

x+5=2y+20

4y+5=2y+20 (as x=4y)

2y=15

y=7.5

so the age of mother is

x=4.(7.5)

x=30

Answer: 58 adults and 38 children went to the concert.

Step-by-step explanation:

Let x= adults , y= children

As per given ,

x+y = 96  (i)

3.75x+3.50y = 350.50     (ii)

Multiply 3.75 to (i) , we get

3.75 x + 3.75y  = 360  (iii)

Eliminate (ii) from (iii)

[tex]3.75 y-3.50y= 360-350.50\\\\\Rightarrow\ 0.25y= 9.5\\\\\Rightarrow\ y=\dfrac{9.5}{0.25}\\\\\Rightarrow\ y= 38[/tex]

put this in (i) ,  x+38 = 96

x= 96-38 = 58

So, 58 adults and 38 children went to the concert.

Answer:

Thus, the statement is False!

Step-by-step explanation:

When the domain of a function has an infinite number of values, the range may not always have an infinite number of values.

For example:

Considering a function

[tex]f(x) = 5[/tex]

Its domain is the set of all real numbers because it has an infinite number of possible domain values.

But, its range is a single number which is 5. Because the range of a constant function is a constant number.

Therefore, the statement ''When the domain of a function has an infinite number of values, the range always has an infinite number of values'' is FALSE.

Thus, the statement is False!

proportional                                            

Answer:

x = - 12

Step-by-step explanation:

Since line with identical signs are parallel and a transversal is making right angle with one of the lines.

So,

[tex](x + 102 ) \degree= 90 \degree \\ \\ x + 102= 90 \\ \\x = 90 - 102 \\ \\ x = - 12[/tex]

Answer:

B) 69°

Step-by-step explanation:

The missing measure is supplementary angle of 111° which means their sum is equal to 180°

180 - 111 = 69.

Step-by-step explanation:

672+6=......+97

[tex]672 + 6 = x + 97 \\ x = 672 + 6 - 97 \\ x = 581[/tex]

none of the options.

Answer:

x = 45°

Step-by-step explanation:

From the triangle given in the picture,

It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.

By the property of isosceles triangle,

Opposite angles of the equal sides are equal in measure.

By triangle sum theorem,

x + x + 90° = 180°

2x + 90 = 180

2x = 180 - 90

x = [tex]\frac{90}{2}[/tex]

x = 45°

The probability that both marbles are blue is 9 percent.

It is given that 12 marbles in a bag, four of them are blue and the rest are green.

To find the probability that both marbles are blue.

The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

Let both the marble be blue for event A.

P(A)=2C4/2C12     (combination formula)

=6/66

=1/11

≅0.09

=9percent.

So ,the probability that both marbles are blue is 9 percent.

The equation of the function f(x) is: f(x) = log2(x − 2) + 2 option (B) f(x) = log2(x − 2) + 2 is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a parent function:

g(x) = log₂x

Answer:

-4 and -1

Step-by-step explanation:

Answer:

-1

Step-by-step explanation:

Turn into slope-intercept form.

x + y = 10

~Subtract x to both sides

y = 10 - x

~Reorder

y = -x + 10

We know that slope-intercept form is y = mx + b where m = slope and b = y-intercept. Thus, the slope is -1.
