Answer:
Add 1 multiply by two
Step-by-step explanation:
As you see when 0 goes to 1, 9 goes to 18 so it is add 1 multiply by two.
Answer:
y=9x+9
Step-by-step explanation:
y=mx+c
You can use any of the 2 points
pnt1. (1;18)
pnt2. (3;36)
find the gradient
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]m = \frac{36 - 18}{3 - 1} [/tex]
[tex]m = \frac{18}{2} [/tex]
[tex]m = 9[/tex]
substitute one point and gradient to find c
y=mx+c
18=9(1)+c
18=9+c
c=18-9
c=9
therefore the equation is y=9x+9

Answer:
1:1:√ 2
Step-by-step explanation:
Answer:
u = 14
v = 14
Step-by-step explanation:
since both angles around the 90 degree angle are the same, also the sides need to be of equal length. v = u
so, we can use Pythagoras
(14×sqrt(2))² = u² + u² = 2u²
196×2 = 2u²
196 = u²
u = 14 = v
hey help me please lol
Answer:
r = 5
Step-by-step explanation:
Side 1: 7
Side 2: 2 + r
To determine r, we subtract 2 from both sides to get the following:
Side 1: 5
Side 2: r
5 and r are the same, so 5 must equal 5.
Therefore, r = 5.

The average weight of 50 teachers is 46kg. If the average weight of gents teachers is 50kg and the average weight of ladies teachers is 40 kg, what is the number of ladies and gents teachers,
Answer:
20 ladies
30 gents
Step-by-step explanation:
Let :
x = number of ladies
50 - x = number of gents
total weight of the ladies = 40x
total weight of the gents = 50(50 - x) = 2500 - 50x
Average weight : (40x +2500 - 50x) / 50 = 46
cross multiply
2500 - 10x = 2300
combine like terms
2500 - 2300 = 10x
200 = 10x
x = 20 = number of ladies
Number of men = 50 - 20 = 30

What is a circle?A circle is a geometric shape that is created by drawing a point in an orbit around a fixed point while maintaining a fixed distance.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
By the circle theorem;
According to the theorem, an angle within a circle is half of the center angle within the circle that subtends the same arc.
Given the ∠FEG = 55°
So angle FG = 2 × ∠FEG
angle FG = 2 × 55° = 110°
Hence angle FG will be 110°.

What is the distance in units between the points (4, -7) and (1, -7)?
Step-by-step explanation:
To evaluate such, the following formula is required:
Distance Formula: d(P, Q) = √ (x2 − x1)^2 + (y2 − y1)^2
Denote the following points as the following,
(4, -7). (1, -7)
X1 Y1. X2. Y2
D(P, Q) = √(1 - 4)^2 + (-7 + 7)^2. <== Since there is a double negative, such will be considered addition.
√(-3)^2 + (0)^2
√9 = 3
Thus, the agglomerate distance of such points on the Cartesian plane is disclosed as 3 units.
A waffle cone has a height of 10 centimeters and a diameter of 6 centimeters. To the nearest tenth of a cubic centimeter, approximately how much ice cream will the waffle cone hold?
Answer:
94.2 cm^3.

Find the volume of this cylinder please..
Answer: 825
Step-by-step explanation:
Plug in the values for v = π*r²*h
So, your new equation is v = π*5²*11 (I got 5 because 10 is the diameter, the radius is half the diameter, therefore r = 5.)
The question is also telling us to replace π with 3.
now we solve, after gathering all of our information.
v = 3*5²*11
v=3*25*11
v=75*11
v=825
I need help with Trigonometric Ration
The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.
The trigonometry ratios for a specific angle ‘θ’ is given below:
Trigonometric Ratios
Sin θ Opposite Side to θ/Hypotenuse
Cos θ Adjacent Side to θ/Hypotenuse
Tan θ Opposite Side/Adjacent Side & Sin θ/Cos θ
Cot θ Adjacent Side/Opposite Side & 1/tan θ
Sec θ Hypotenuse/Adjacent Side & 1/cos θ
Cosec θ Hypotenuse/Opposite Side & 1/sin θ
Note: Opposite side is the perpendicular side and the adjacent side is the base of the right-triangle. Also, check out trigonometric functions to learn about each of these ratios or functions in detail.Trigonometric Identities
Definition
Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.
The three sides of the right triangle are:
Hypotenuse (the longest side)
Perpendicular (opposite side to the angle)
Base (Adjacent side to the angle)

For the right triangle shown, use the trig functions to find the value of x. Round your answer to the nearest tenth
Answer:
28.3
Step-by-step explanation:
Use the Tangent
Tan(theta) = opposite over adjacent.
opposite (defined as the line that does not make up the angle) = 17
Theta = 31
adjacent (one of the lines making up the angle) = x
Tan(31) = 0.6009
Tan(31) = 17/x Multiply both sides by x
x*tan(31) = 17 Divide by tan 31
x = 17/tan31
x = 17 / 0.6009
x = 28.29
Rounded to the nearest 1/10 is 28.3
62+2{56/(4 multipied by 2)-5
Answer:
Hence The Answer is 66.
Step-by-step explanation:
I Hope It Helps You.
• • •
The simplified expression is 99.3333 (rounded to four decimal places).
To simplify the expression 62 + 2{56/(4 multiplied by 2) - 5}, we'll follow the order of operations (also known as PEMDAS).
First, within the innermost parentheses, we have 4 multiplied by 2, which equals 8. Then, we subtract 5 from 8, resulting in 3.
Next, we have 56 divided by 3, which equals 18.6667 (rounded to four decimal places).
Now, we'll move to the outer set of curly braces. We multiply 18.6667 by 2, giving us 37.3333 (rounded to four decimal places).
Finally, we add 62 to 37.3333, resulting in 99.3333 (rounded to four decimal places).

The graph of which functions has an axis of symmetry at x = -1/4?
Answer:
2x^2 + x - 1
If I did anything you didn't understand let me know so I can explain.
Step-by-step explanation:
All of them are quadratics so let's use that.
The first one is 2x^2 + x - 1. To find the axis of symmetry the strategy is usually to find the two zeroes of a quadratic and pick the number between them. Something to notice though is that 2x^2 + x - 1 is just 2x^2 + x sshifted down 1, so they both have the same axis of symmetry. So I am going to ignore the constant, because then finding the zeroes is much much simpler. I am going to do this with all opions.
So 2x^2 + x - 1 I am just going to use 2x^2 + x. If you factor out an x you get x(2x + 1) So now we have it in factored form and we know the zeroes are 0 and -1/2. The number directly in between these is -1/4, so the axis of symmetry is x = -1/4. I don't know if there is only one with that axis of symmetry so i am going to check the rest.
2x^2 - x + 1 means we are only going to look at 2x^2 - x. factoring we get x(2x - 1) so the zeroes are 0 and 1/2, so the axis of symmetry is at 1/4.
x^2 + 2x - 1 we only use x^2 + 2x. Factored form is x(x+2) so zeroes are 0 and -2 whichh means axis of symmetry is -1
x^2 - 2x + 1 has the same axis of symmetry as x^2 - 2x, which has zeros at 0 and 2 so the axis of symmetry is at 1.
So yep, it was just the first one.

Answer:
(a) f(x) = 2x^2 +x -1
Step-by-step explanation:
For ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the offered answer choices, the axes of symmetry are ...
a) x = -1/(2·2) = -1/4 . . . . . . the function we're looking for
b) x = -(-1)/(2·2) = 1/4
c) x = -2/(2·1) = -1
d) x = -(-2)/(2·1) = 1
The function with axis of symmetry x = -1/4 is f(x) = 2x^2 +x -1.
