Answer:
FD = 26Step-by-step explanation:
CD = ED --- (secant property)
so, ==>>
13x - 16 = 4x + 11
13x - 4x = 11 + 16
9x = 27
x = 27÷9
x = 3
side ED = 4x + 11 = 4×3 + 11
side ED = 23
side FE = 12
ΔFED = 90° ...... (tangent secant property)
so.........
FE² + ED² = FD² ......... ( by pythagoras theorm)
12² + 23² = FD²
144 + 529 = FD²
673 = FD²
√673 = FD
26 = FD

26

Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + (2.1)^2 = (2.9)^2
a^2 +4.41=8.41
a^2 = 8.41-4.41
a^2 =4
Take the square root of each side
sqrt(a^2)=sqrt(4)
a=2

A right circular cone is shown. The base of the cone is a circle with the center at point A. The Distance from point A to point C is 16 inches. The distance from point C to point B is 20 inches.
Answers
Answer:
6.4
Step-by-step explanation:
The distance between the point A and B is 12 inches which is the radius of the cone. Thus, The diameter of the cone will be 24 inches.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
A right circular cone is shown.
The base of the cone is a circle with the center at point A.
The Distance from point A to point C is 16 inches.
The distance from point C to point B is 20 inches.
[tex]|BC|^2 = |AB|^2 + |AC|^2 \\\\|20|^2 = |AB|^2 + |16|^2 \\\\AB = \sqrt{400 - 256}\\\\AB = \sqrt{144} \\\\AB = 12[/tex]
Therefore, the distance between the point A and B is 12 inches which is the radius of the cone.
Thus, The diameter of the cone will be 24 inches.

Answers
Answer:
Y=-x+1
Step-by-step explanation:
Answer:
y=-x+1
Step-by-step explanation:
to get this you use the point-slope formula
y-y1=m(x-x1) - plug in the coordinates and find the slope
y--3=-1(x-4) - change the sign and solve the parentheses
y+3=-x+4 - subtract 3 from both sides to get y by itself
y=-x+1
Jenny works 30 hours and is paid £318 Calvin works 28 hours and is paid £287 Jenny is paid more per hour than Calvin How much more
Answers
Answer:
£0.35 more per hour.
Step-by-step explanation:
Jenny:
30h = £318
1h = £318 ÷ 30
= £10.60
Calvin:
28h = £287
1h = £287 ÷ 28
= £10.25
Difference:
£10.60 - £10.25 = £0.35

Slope = (difference of y-coordinates)/(difference of x-coordinates)
= (-3 - (-4))/(4 - 1) = 1/3
Answer:
slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (4, - 3) ← 2 points on the line
m = [tex]\frac{-3+4}{4-1}[/tex] = [tex]\frac{1}{3}[/tex]
Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 12 units above the vertex of the graph of g(x) .
Which pair of functions could have been used to create the graphs of g(x) and h(x)?
h(x)=(x+12)2 and g(x)=x2
h(x)=x2−12 and g(x)=x2
h(x)=x2+12 and g(x)=x2
h(x)=(x−12)2 and g(x)=x2
Answers
Answer:
h(x) = x^2 + 12 and g(x) = x^2
Step-by-step explanation:
In this case there is a positive, vertical translation of 12 units up.
The original g(x) = x^2 has its vertex at (0, 0), whereas h(x) has its vertex at (0, 12). The function h(x) is found by adding 12 to g(x) = x^2:
h(x) = x^2 + 12
The third answer choice is the correct one: h(x) = x^2 + 12 and g(x) = x^2
Question 1 of 5 Select the correct answer. If the factors of quadratic equation are (x − 7) and (x + 3), what are the x-intercepts? (-7,0) and (-3,0) (-7,0) and (3,0) (3,0) and (7,0) (-3,0) and (7,0)
Answers
Answer:
(7,0) and (-3,0)
Step-by-step explanation:
Given the factors, we want to get the x-intercepts
All we have to do is to get the x values by equating the factors to zero
we have this as;
(x -7) = 0 and (x + 3) = 0
x = 7 and x = -3
The x-intercepts are;
(7,0) and (-3,0)

A jar had 88 coins. 1/3 of the coins were silver. How many coins were gold?
Answers
Answer:
There are 66 gold coins in the jar
Step-by-step explanation:
Let the number of silver coins = X
Then the number of gold coins = 3X (as there are 1/3 number of silver coins as gold)
Total coins =88
Total coins = silver coins + gold coins
Total coins = X + 3X = 88
Total coins = 4X = 88
X = 88/4
X = 22
No. Of silver coins = 22
No. Of gold coins = 3X = 3×22
No. Of gold coins = 3X= 66
Check
Total coins = 3X + X = 88
66+22 = 88
88 = 88
Hope it helps...
Have a great day :P
Answer:
Hello There!!
Step-by-step explanation:
Let the number of silver coins be x and gold coins be 3x which add up to 4x. Make an expression and add 88 with 4x so 4x=88
x=22(88÷4).
So x=22[silver coins]
3x=66(22×3) [gold coins]
hope this helps,have a great day!!
