Answer:
y= -1/2x+4
Step-by-step explanation:
slope = rise/run on the graph. the graph is going down, so it's negative. find where the line intersects the graph at a point and then count the squares up and over until it meets again. the line meets at (6,1), you count up one square and over 2 and it meets again. this gives you your rise/run = 1/2. the y intercept is where the line intersects the y axis. here the y intercept is 4 because the like goes through 4 at the y axis.
Find the area of this semi-circle with radius, r = 6cm.
Give your answer as an expression in terms of pi
Answer:
72π (I think)
Step-by-step explanation:
Think of it in terms of the entire circle. A semi-circle is just half a circle, so the area of a semicircle will be half of the area of the entire circle. The radius of the semicircle is 6, so the radius of the whole circle is 12. Then, we can do [tex]\frac{pi*r^{2} }{2}[/tex] to get the area of the semicircle is 72π. I'm pretty sure that's right. Let me know if I made a mistake somewhere.
The original price of a bicycle was $400. Now it is on sale for $300. What percentage of the original price was the markdown?
Answer:
25%
Step-by-step explanation:
400/100•300/x=0.75
1.00-0.75= 0.25
25%
Answer:
25 percent of discount
Step-by-step explanation:
[tex]original_price=400\\final_price=300\\discount=100\\\\\frac{400*percent}{100}=100 =>percent=\frac{100^2}{400}=25[/tex]

A tin has a radius of 3cm anf height 6cm. Find the volume, in litres of the liquid that will fill the tin to capacity, correct to 2 decimal places
Answer:
The capacity of tin is 0.17 liter.
Step-by-step explanation:
radius, r = 3 cm
height, h = 6 cm
The capacity of the tin is given by
[tex]V =\pi r^2 h\\\\V =3.14 \times 3\times 3\times 6\\\\V = 169.56 cm^3[/tex]
Now
1000 cubic cm = 1 liter
So, the capacity in liter is
V = 0.169 liter = 0.17 liter
What is the value of cos0 ?
Answer:
[tex]\frac{9}{10}[/tex]
Step-by-step explanation:
The Law of Cosines works for any triangle and is given by:
[tex]c^2=a^2+b^2-2ab\cos \gamma[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are the sides of the triangle and [tex]\gamma[/tex] is the angle opposite to [tex]c[/tex].
In the given triangle, assign the variables:
[tex]c\implies 10[/tex] [tex]a\implies 10[/tex] [tex]b\implies 18[/tex]Substituting these variables, we have:
[tex]10^2=10^2+18^2-2(10)(18)\cod \cos \gamma,\\100=100+324-360\cdot \cos \gamma,\\100=424-360\cos \gamma,\\-324=-360\cos\gamma,\\\cos \gamma =\frac{-324}{-360}=\boxed{\frac{9}{10}}[/tex]
A chess player moves a knight from the location (3, 2) to (5, 1) on a chessboard. If the bottom-left square is labeled (1, 1), the translation made is 2 squares up, 1 square right1 square down, 2 squares left1 square down, 2 squares right2 squares down, 1 square right. If the player moves the knight from (5, 1) to (6, 3), the translation made is 1 square up, 1 square right2 squares up, 1 square right4 squares up, 2 squares right2 squares up, 1 square left.
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Translation is the movement of a point either up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units up and b units right, then the new point is at A'(x + b, y + a).
Given that the knight is moved from (3, 2) to (5, 1), hence it is moved 2 squares right and 1 square down.
If the knight is moved from (5, 1) to (6, 3), it is moved 1 square right and 2 squares up.

Question
Given the function below, if f(x) = -1, find the value of x.
f (x) = 4x + 11
soln
given,
f(x) = 1
Now,
f(x) = 4x+11
or, -1 =4x +11
or,4x = 11+1
or, 4x = 12
or, x. =12/4
or x. = 3
Therefore, The value of x is 3.

Step-by-step explanation:
Since this is a right triangle, we will use a right triangle trig identity to solve our problem. The side opposite the reference angle A is given as 5, and the side adjacent to the reference angle is given as 7. The trig ratio that uses the sides opposite and adjacent is the tangent ratio:
[tex]tanA=\frac{5}{7}[/tex]
Hit the 2nd button on your calculator then the tan button which displays:
[tex]tan^{-1}([/tex]
Enter 5/7 after that open parenthesis and hit = to get that

sorry if i am asking a lot, totally suprised by this and dont know what to do and yall are great, i need to find X and Y with exact values and no decimals
Answer:
x and y = 19
Step-by-step explanation:
sin 45/x = sin90/19[tex]\sqrt{2}[/tex]
19[tex]\sqrt{2}[/tex]×sin45=sin90x
x=19
Pythagorean theorem for y
[tex]y^{2}[/tex]=(19[tex]\sqrt{2}[/tex])^2 - 19^2

For one month Sierra calculated her home towns average high temp in degrees Fahrenheit she wants to convert that temp from degrees Fahrenheit to degrees Celsius using the function c(f)=5/9(f-32). What does C(F)
Answer:
C(F) means Celcius temperature value from Fahrenheit temperature
Step-by-step explanation:
C(F) is Mathematically interpreted as C of F, this means the value of C obtained for a given F value, that is we have a relation, expression or formular exoressed in terms of F which can be used to obtain the Value of C for a given value of F by making necessary substitution.
Here the relation or expression is c(f)=5/9(f-32).
Hence, once we are given a particular F value, we can substitute that into the equation and obtain the corresponding C temperature value.
