Explain how you would use trig ratios to find the height of the tree if you know you are standing 30 feet from the base of the tree when you measure the 37-degree angle.
Answers
make sure your calculator is in Degree mode.
From use of trigonometric ratios, it is seen that the height of the tree is; 22.61 feet
How to work with trigonometric ratios?We are told that you are standing 30 ft from the base of a tree.
Now, the distance from where you are standing to the top of the tree will be the hypotenuse of the triangle formed by you and the tree.
Thus, if the height of the tree is h and the angle the hypotenuse makes with the 30 ft base is 37°, then we have;
h/30 = tan 37
h = = 30 * tan 37
h = 22.61 ft

20x⁶/15y⁵ × 5y²/6x⁴
The first thing to do is to simplify the easiest terms: the constants. Just multiply all the constants on the numerator and all the constants on the denominator independently. The simplified constant becomes
(20*5)/(15*6) = 10/9
So, the equation to be solved now is
10x⁶y²/9y⁵ x⁴
So, I also multiplied all the variables in the numerator and denominator independently, just like the constants. Then, you apply the laws of exponents. When you divide terms with exponents of the same value of the base, you subtract the exponent on the numerator minus the denominator. It goes like this:
10/9 * x⁶⁻⁴*y²⁻⁵ = 10/9*x²y⁻³
Now, when the exponent as written to the power of a negative exponent, just simply take its reciprocal to make it positive. So, the final answer is
10x²/9y³ or that is letter D.
How many ways are there to place 5 basketball players on the court if you must place 2 guards, 2 forwards and a center, from a team of 12, consisting of 4 guards, 5 forwards and 3 centers?
Answers
Final answer:
There are 180 ways to place 5 basketball players on the court, selecting 2 guards, 2 forwards, and 1 center.
Explanation:
To determine the number of ways to place 5 basketball players on the court, we need to find the number of combinations of guards, forwards, and centers that can be selected from the available players. There are 4 guards, 5 forwards, and 3 centers in the team.
The number of ways to select 2 guards from 4 is C(4,2) = 6.
The number of ways to select 2 forwards from 5 is C(5,2) = 10.
The number of ways to select 1 center from 3 is C(3,1) = 3.
By the multiplication principle, the total number of ways to place the players on the court is 6 × 10 × 3 = 180.
A hyperbola with center at (0, 0), with x-intercepts at (4, 0) and (-4, 0), with b = 1, and opening horizontally has the equation
Answers
Answer:
It´s x2/16-y2/1=1
Step-by-step explanation:
The equation of the hyperbola is x²/16 - y²/1 =1
What is a hyperbola?A symmetrical open curve formed by the intersection of a circular cone with a plane at a smaller angle with its axis than the side of the cone. A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.
Given here: hyperbola with center at (0, 0), with x-intercepts at (4, 0) and (-4, 0), with b = 1 . Now we know The standard equation of the hyperbola is [(x²/a²) – (y²/b²)] = 1, where the X-axis is the transverse axis and the Y-axis is the conjugate axis.
Therefore the hyperbola opening horizontally has the equation with x-intercepts at (4, 0) and (-4, 0), with b = 1 is x²/16 - y²/1 =1
Hence, The equation of the hyperbola is x²/16 - y²/1 =1

Which lines can you conclude are parallel given that m14 + m2 = 180? Justify your conclusion with a theorem.
Answers
because m<14 and m<2 are in lines a and b and they aren't corresponding angles
Answer:
Option 2 is correct.
Step-by-step explanation:
Given the diagram and also the condition m∠14 + m∠2 = 180°
we have to tell which lines are parallel.
By the theorem of exterior angles
Same-side exterior angles which are formed outside of the parallel lines and on same side of transversal line.
The theorem states that when parallel lines are cut by a transversal line, the sum of the same-side exterior angles is 180° i.e these are supplementary.
∴ Lines a and b are are parallel by converse of same side exterior angle theorem.
For the following true conditional statement, write the converse. If the converse is also true, combine the statements as a biconditional. If x = 3, then x2 = 9.
Answers
Answer: The converse of the given statement is if [tex]x^2=9[/tex] ,then x=3.→ which is not true.
We cannot form a biconditional statement for the given statement because the converse is not true.
Step-by-step explanation:
Given statement: If x = 3, then [tex]x^2=9[/tex]
The converse statement of conditional statement that "if p then q" is "if q then p".
therefore, the converse of the given statement is if [tex]x^2=9[/tex] ,then x=3.
But the converse is not true since if [tex]x^2=9[/tex] then x can be 3 or -3 .
∵ [tex]3^2=9[/tex] and [tex](-3)^2=9[/tex]
A biconditional statement is true if and only if both the conditional statement and its converse are true.
Therefore, we cannot form a biconditional statement for the given statement because the converse is not true.
The converse of the conditional statement 'If x=3, then x²=9' is 'If x²=9, then x=3'. As both these statements are true, they can be combined into a biconditional statement 'x=3 if and only if x²=9'.
Explanation:
In your question, you asked how to write the converse of a given conditional statement and then combine them if the converse is also true. The original conditional statement is 'If x = 3, then x² = 9.' The converse of this statement would be 'If x² = 9, then x=3.' In this case, the converse is also true because if x² equals 9 then x does indeed equal 3. Therefore, we can combine the conditional statement and its converse into a biconditional statement: 'x = 3 if and only if x² = 9.'

A piece of metal with a mass of 140. g is placed in a 50 mL graduated cylinder. The water level rises from 20. mL to 41 mL. What is the density of the metal?
Answers
2. 1 milliliter of water has a volume of 1 cubic centimeters.
3. Mass= Density * Volume

The water level rises from 20.mL to 41.mL means that a volume of 21mL of water has been displaced.
This means that the volume of the object is 21 cm cubed. (by 1 and 2)
By 3, the density of the piece of metal is:
Density=Mass/Volume=140 g / 21 cm^3= (140/21) g/cm^3=6.67 g/cm^3
Answer: 6.67 g/cm^3
A rectangular patio is 9 ft by 6 ft. When the length amd width are increased by the same amount, the area becomes 88 sq ft. Ginger is using the zero product property to solve the equation (6+x)(9+x)= 88. What do her solutions represent?
Answers
The solutions represent the additional length and width that need to be added to the original dimensions to achieve the desired area of 88 sq ft.
Explanation:The equation is: (6+x)(9+x) = 88. Ginger is using the zero product property to solve for x. The solutions she finds represent the value of x that, when added to both the length and width of the original patio, will result in a patio with an area of 88 sq ft.
By solving the equation, Ginger will find the possible values of x that will make the area of the new patio equal to 88 sq ft. These values represent the additional length and width that need to be added to the original dimensions to achieve the desired area.
For example, if Ginger finds that x = 2, then the new patio dimensions would be 9+2 = 11 ft by 6+2 = 8 ft, resulting in an area of 11 * 8 = 88 sq ft.

a.13
b.23

d.70
Answers
Final answer:
In an isosceles triangle with angles B and C congruent, and with m∠A equal to 40°, the equation to find x is 40° + 2(3x + 1)° = 180°. Solving this equation yields x = 23°, which corresponds to option b.
Explanation:
Since ΔABC is an isosceles triangle and angles B and C are congruent, m∠B = m∠C. Given that m∠A = 40°, we can set up an equation to find x since the sum of all angles in a triangle equals 180°.
Equation: 40° + (3x + 1)° + (3x + 1)° = 180°
Combining like terms:
40° + 2(3x + 1)° = 180°
40° + 6x + 2° = 180°
6x + 42° = 180°
6x = 180° - 42°
6x = 138°
x = 23°
Therefore, the value of x is 23°, which corresponds to option b.

the water was pumped out of a backyard pond. what is the domain of this graph
Answers
Time t would be the domain, 0 to t.
The domain of a graph represents the set of all the possible x-values for a function. In the context of this question, the domain could represent all the possible time values it took for water to be pumped out of the pond. However, the exact domain can't be identified without specific graph or additional information.
Explanation:To determine the domain of the graph related to the water being pumped out of a backyard pond, you would need to consider the horizontal range of the graph. The domain of a graph in mathematics represents the set of all the possible x-values that the function can have. In the context of this problem, the domain could represent the time over which the water was being pumped out. The dependence of the quantity of water on the time creates a function whose domain (all possible time values during the pumping) we are looking for. However, without the specific graph or additional information, we cannot directly identify the domain.

A = 120' x 80'
A = 9600 ift
Then, we convert the area in ft² to acres,
A = (9600 in²)(2.3 x 10^-5/ 1 in²)
A = 0.24 acre
The portion of land remaining is,
A of remaining = 0.25 acre - 0.24 acre
= 0.1 acre
The remaining portion is for Andre's studies.
This, 0.1 ft² is equal to the 4% of the given area of the court.
Answer:
Answer is approx 12%
Step-by-step explanation:
Total land owned by Andre = [tex]\frac{1}{4}=0.25[/tex] acres
He wants to construct a 120 feet x 80 feet tennis court on the lot.
Means the area of the court will be = [tex]120\times80=9600[/tex] square feet.
9600 square feet = 0.22 acres (divide the area value by 43560 as 1 acre has 43560 sq feet)
Area left in acres = [tex]0.25-0.22=0.03[/tex] Acres
