What is the y-intercept of y = sinx?
Answer:
The y-intercept is 0
Step-by-step explanation:
Here, we want to get the y-intercept value of y = sin x
From the plot of the graph, we can see that the graph of sin x touches the y-axis at the point y = 0
So therefore, the y-intercept of y = sin x is 0

Answer:
both are reciprocals
Step-by-step explanation:
15.
[tex]\frac{5}{8}\cdot \frac{16}{20}\\\\=\frac{5}{8}\cdot\frac{8}{5}=1[/tex]
so they are reciprocals
17.
[tex]\frac{2}{3}\cdot\frac{12}{18}\\\\=\frac{2}{3}\cdot \frac{3}{2}=1[/tex]
so they are reciprocals
if the radius is 14cmand The perimeter of the sector is 57.32cm.
what is the size of the angle?
Answer:
120°
Step-by-step explanation:
A sector of a circle is the portion or region of a circle enclosed by two radii and an arc. The perimeter of a the sector of a circle is given by the formula:
Perimeter of sector = [tex]\frac{\theta}{360} *2\pi r[/tex] + 2r
Where θ is the angle which forms the sector and r is the radius of the circle.
Given that Perimeter of sector = 57.32 cm, radius (r) = 14 cm, we can find the angle θ using:
Perimeter of sector = [tex]\frac{\theta}{360} *2\pi r[/tex] + 2r
[tex]57.32=\frac{\theta}{360} *2\pi *14+2(14)\\\\57.32-28=\frac{\theta}{360} *2\pi *14\\\\29.32=\frac{\theta}{360} *2\pi *14\\\\ \frac{\theta}{360}=\frac{29.32}{2\pi *14} \\\\\frac{\theta}{360}=0.33\\\\\theta=120^o[/tex]

If y = -5, what is the value of
2y+2
-
4
Answer:
-12
Step-by-step explanation:
Ok so I'm guessing that's a -4 but if its not, please correct me.
y= -5 is going to be plugged into 2y+2-4
This means that 2(-5)+2-4=?
2(-5) is the equivalent to 2 times -5, which is -10 (you solve multiplication first because order of operations)
Now, 2-4=-2
So using this, let's combine both equations!
-10+-2=?
?=-12
It's a lot of steps but they get easier the more you do them <3

3y-z ; use y=6 and z=6
Answer:
12
Step-by-step explanation:
y = 6; z = 6
3y - z = 3(6) - 6 = 18 - 6 = 12
Answer:
12
Step-by-step explanation:
3y-z is asking 3 x 6 - 6, which equals 12
(3 x 6 = 18 and 18 - 6 = 12)
Find a solution for
-2/9 = 4/m
I think its -18

Fifteen bicyclists entered a race. In how many different orders can the top five finish so that awards can be given?
pls help !!
Answer:
They can finish the race in 15 x 14 x 13 x 12 x 11 = 360360 order.
Step-by-step explanation:
There are 15 bicyclists in the race. The first position would come from the first bicyclist to the 15th. Meaning the first position can be occupied by 15 individuals. The second position can only be occupied by 14 individuals since one person is already first. Same way the third, fourth and fifth positions can be occupied by 13, 12 and 11 individuals respectively.
Therefore, they can finish the race in
15 x 14 x 13 x 12 x 11 = 360360 order.

Learning task 2
A.for this learning task,be able to supply the missing value if y varies jointly or if y varies both directly and inversely to x and z.
Step-by-step explanation:
Row 1
k=2 , Equation: y=2xzRow 2
x=10, k=2Row 3
y= 192, Equation: y= 4xzRow 4
z= 2, k= 3Row 5
x= 16/3, k= 3/4Note. The equation should be y = 3/4xz, not y = 3/4xy

What is the slope of the line -3 y = 12 x + 6?
Answer:
Slope = - 4
Step-by-step explanation:
-3y = 12x + 6
Divide the equation by (-3)
[tex]\frac{-3y}{-3}=\frac{12}{-3}x+\frac{6}{-3}\\\\[/tex]
y = -4x - 2
Compare with y = mx + b
m = -4
