20 POINTS!!!!!!!!! pls answer asap

Answer:

2

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

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

Answer:

the answer is 6a

Step-by-step explanation:

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!!

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)

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

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

Hope this helps

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.

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.

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
