Step-by-step explanation:
The given triangle is a right triangle, this is indicated by the box around one of the angles, signifying that the angle is a (90) degree angle. Therefore, to solve this problem one must use trigonometric ratios. These ratios are used to describe the relationship between an angle and the sides in a right triangle.
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\\[/tex]
Bear in mind, the names of the sides of the triangle are relative to the angle that one uses to describe it in the triangle. Therefore the (opposite) and (adjacent) sides will change depending on the angle one chooses to look at it from.
In this case, one is given the length of the side opposite the given angle. One is asked to find the measure of the side adjacent to the angle. Therefore, it would make the most sense to use the tangent (tan) ratio.
[tex]tan(\theta)=\frac{opposite}{adjacent}[/tex]
Substitute,
[tex]tan(20)=\frac{9}{x}[/tex]
Manipulate the equation such that it is solved for (x),

Mariano is standing at the top of a hill when he kicks a soccer ball up into the air. The height of the hill is h feet, and the ball is kicked with an initial velocity of v feet per second. The height of the ball above the bottom of the hill after t seconds is given by the polynomial –16t2 + vt + h. Find the height of the ball after 2 seconds if it was kicked from the top of a 60 foot tall hill at 84 feet per second.
The height of the ball after 2 seconds is 100 feet.
What is the height function?
A height function exists as a function that quantifies the intricacy of mathematical objects. The height of an object, h(t), exists defined by the formula [tex]-16 t^{2}[/tex] + vt + h.
Given: Let, the polynomial equation be [tex]-16 t^{2}[/tex] + vt + h
h = 20 ft and v = 72 ft/s
y = [tex]-16 t^{2}[/tex] + 72t + 20
To estimate the height of the ball after 2 seconds
substitute the value of t = 2, then
y = -16 [tex]\times[/tex] 4 + 72 [tex]\times[/tex] 2 + 20
= -64 + 144 + 20
= 100 feet
The height of the ball after 2 seconds is 100 feet.

Answer and Step-by-step explanation:
In a polygon, when a shape is similar but dilated, the angles are still congruent.
Also, turn the pentagon QRSTP counterclockwise 90 degrees so it is upright and looks like pentagon ABCDE (making it easier to read).
A. The measure of angle P is 124 degrees, as it matches up with angle E.
B. To find the length of side r, we need to find the scale factor. We do this by looking at the given side on pentagon QRSTP (side RS) and match it with its similar side of pentagon ABCDE (side BC)
To find the scale factor, you divide the side of the bigger shape by the side of the smaller shape. For us, this results in the scale factor being 2.
Now, the similar side to r is side ED. We need to divide 7.5 by 2 to find r.
When doing so, we get r to be 3.75.

The braking distance (dm) of a car is directly
proportional to the square of its speed (v m/s)
When the speed of the car is increased by
50%, what is the percentage change in its
braking distance?
Answer:
Step-by-step explanation:
We can assign variables as:
d = original breaking distance
b = original speed of the vehicle
d′ = increased breaking distance
b′ = increased speed of the vehicle
We can look at it this way, originally it was like this:
d=kb2
Now, if we increase the speed to b’ which 200% more than b, we will have
d′=k(b′)2
d′=k(b+2b)2
d′=k(3b)2
d′=9kb2
Obtaining the difference between d and d’, we have
d′−d=9kb2−kb2
d′−d=8kb2
in terms of d
d′−d=8(kb2)
d′−d=8d
Adding d on both sides of the equation,
d′=d+8d
Which means the original breaking distance is increased by 800%. This is similar to the phrase “the speed of the vehicle is increased by 200%” which translates to “b + 2b”.
Hope this answer helps you :)

There is a 100% increase in the braking distance after 50% increase in speed.
What is speed?A body is said to be of speed v m/s if it travels v meter per second.
How to solve it?The braking distance of a car is directly proportional to the velocity of its speed(v m/s)
When the speed of the car is increased by 50% then the speed of the car v m/s becomes (3v/2) m/s.
The braking distance of a car is directly proportional to the square of its speed hence, the braking distance becomes
v²c where c is some constant.
So, the braking distance after 50% of the car speed is increased becomes (3v/2)²c₁, where c₁ is some constant.
Hence, the percentage change in the car's braking distance is
[tex]\frac{\frac{9}{4}-\frac{3}{2}}{\frac{3}{2}}[/tex]
[tex]=\frac{\frac{9-6}{4}}{\frac{3}{2}}\\=1[/tex]
That means there is a 100% increase in the braking distance after 50% increase in speed.

Answer:
Option B is correct
Step-by-step explanation:
From the image of the double given, when we cut a section vertically through the centre where the tips of the cones meet, when we look at the cut section, we will not see curves but straight lines meaning that the top and bottom will be horizontal lines and not curves.
Also, the meeting point of the two cone tips will remain the same.

For about 10 years after the French Revolution, the French government attempted to base measures of time on multiples of ten: One week consisted of 10 days, one day consisted of 10 hours, one hour consisted of 100 minutes, and one minute consisted of 100 seconds. What are the ratios of (a) the French decimal week to the standard week and (b) the French decimal second to the standard second
Answer:
[tex](a)\ Ratio = 1.43[/tex]
[tex](b)\ Ratio = 0.864[/tex]
Step-by-step explanation:
Given
[tex]French\ Week= 10\ days[/tex]
[tex]French\ days= 10\ hours[/tex]
[tex]French\ hours= 100\ minutes[/tex]
[tex]French\ minutes= 100\ seconds[/tex]
Solving (a): Ratio of french minute to standard week
This is calculated as:
[tex]Ratio = \frac{French\ week}{Standard\ week}[/tex]
[tex]Ratio = \frac{10\ days}{7\ days}[/tex]
[tex]Ratio = \frac{10}{7}[/tex]
[tex]Ratio = 1.43[/tex]
Solving (b): Ratio of french second to standard second
This is calculated as:
[tex]Ratio = \frac{French\ second}{Standard\ second}[/tex]
Convert french days to seconds
[tex]French\ days= 10\ hours[/tex]
[tex]French\ days = 10hr * 100mins/hr * 100secs/min[/tex]
[tex]French\ days = 10 * 100 * 100secs[/tex]
[tex]French\ days = 100000\ secs[/tex]
This gives:
[tex]French\ second = \frac{1}{100000}day[/tex]
For standard day, we have:
[tex]Standard\ second = \frac{1}{86400}day[/tex]
So, we have:
[tex]Ratio = \frac{1/100000}{1/86400}[/tex]
Rewrite as:
[tex]Ratio = \frac{1}{100000} \div \frac{1}{86400}[/tex]
[tex]Ratio = \frac{1}{100000} * \frac{86400}{1}[/tex]
[tex]Ratio = \frac{86400}{100000}[/tex]
[tex]Ratio = 0.864[/tex]

Find the area of each figure
Answer:
92
Step-by-step explanation:
this figure can be "split" into 3 sub-figures.
one rectangle in the middle, one triangle to the right, and one triangle on top.
these areas we can calculate very easily. and then we simply sum up all 3 of them and we have the answer.
it is clear, the area of a rectangle is length×width.
and the area of triangle is baseline×height/2.
where in a right-angled triangle one of the sides next to the 90 degree angle is the baseline and the other is the height.
the rectangle
R = 10×6 = 60
the triangle to the right
T1 = (14-10)×6/2 = 12
the triangle on the top
T2 = 10×(10-6)/2 = 20
so, the total area is
60+12+20 = 92
The area of the given figure is 92.
This figure contained 3 sub-figures.
One rectangle in the middle, one triangle to the right, and one triangle on top.
The area of these areas we can calculate very easily. and then we ad all 3 of them and we have the answer.
What is the area of a rectangle?The area of a rectangle is,
[tex]A=length\times width.[/tex]
What is the area of triangle?The area of triangle is
[tex]A^*= \frac{1}{2} \times base\times height[/tex]
Where in a right-angled triangle one of the sides next to the 90 degree angle is the baseline and the other is the height.
The area of rectangle
[tex]R =l\times w \\R=10\times 6 \\R= 60[/tex]
The triangle to the right
[tex]T_1 = (14-10)\times 6/2 = 12[/tex]
The triangle on the top
[tex]T_2 = 10\times (10-6)/2 = 20[/tex]
Therefore, the total area is,
60+12+20 = 92
Therefore the area of the given figure is 92.
