Find the x-intercept of the parabola with vertex (6,27) and y-intercept (0,-81)

Answers

The vertex form of the equation of a parabola with the vertex (h,k):
$y=a(x-h)^2+k$

The parabola has the vertex at (6,27).
$y=a(x-6)^2+27$

The y-intercept is (0,-81).
$x=0, \ y=-81 \n\Downarrow \n-81=a(0-6)^2+27 \n-81=a(-6)^2+27 \n-81=36a+27 \n-81-27=36a \n-108=36a \n(-108)/(36)=a \na=-3$

The equation of the parabola is:
$y=-3(x-6)^2+27$

y=0 at the x-intercepts.
$0=-3(x-6)^2+27 \n-27=-3(x-6)^2 \n(-27)/(-3)=(x-6)^2 \n9=(x-6)^2 \n√(9)=√((x-6)^2) \n3=|x-6| \nx-6=3 \ \lor \ x-6=-3 \nx=3+6 \ \lor \ x=-3+6 \nx=9 \ \lor \ x=3$

The x-intercepts are x=3 and x=9.

Please help me! I’m so confused!! I will give BRAINLIEST :) A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.

If angle BAC = 22 degrees the angle ABC = ?

Answers

Answer:

136 degrees

Step-by-step explanation:

if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136

Answer:

Angle ABC is equal to 136 degrees.

Step-by-step explanation:

Since sides AB and BC are congruent (meaning they are equal to each other), they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.

Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.

136 + 22 + 22 = 180, so this works!

I hope this helps!

Hudson bought snacks for his team's practice. he bought a bag of apples for $1.59 and a 10-pack of juice bottles. the total cost before tax was $7.39. write and solve an equation which can be used to determine xx, how much each bottle of juice cost

Answers

The cost of each bottle of juice will be $0.58.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Hudson bought snacks for his team's practice. he bought a bag of apples for $1.59 and a 10-pack of juice bottles. the total cost before tax was $7.39.

The expression will be formed as below:-

10x + 1.59 = 7.39

Here x is the cost of the juice bottle.

10x + 1.59 = 7.39

10x = 7.39 - 1.59

10x =5.8

x = 5.8/10 = $0.58

Therefore, the cost of each bottle of juice will be $0.58.

You drop a ball from a height of 0.5 meter. Each curved path has 52% of the height of the previous path.a. Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.
b. What height will the ball be at the top of the third path?

Answers

Answer:

$f(n)=0.5(0.52)^(n-1)$
0.14 m

Step-by-step explanation:

The initial height of the ball is 0.5 m

Each curved path has 52% of the height of the previous path, i.e the height of the ball after one bounce will be,

$=(52)/(100)* 0.5\n\n=0.52* 0.5\ m$

The height of the ball after 2 bounces will be,

$=(52)/(100)*(0.52* 0.5)$

$=0.52*0.52* 0.5$

$=0.52^2* 0.5\ m$

Hence the series becomes,

$0.5,0.5(0.52),0.5(0.52)^2,............$

This is the case of Geometric Progression.

But as it is given that the initial height will be given by n=1, so the rules for finding the height f(n) after n bounces would be,

$f(n)=0.5(0.52)^(n-1)$

Putting n=3, we can get the height of the ball of the third path,

$\Rightarrow f(3)=0.5(0.52)^(3-1)=0.5(0.52)^(2)=0.14\ m$

This is a geometric sequence. The first term is the max height of the first curved path, which is 0.5. The second one is 52% of that meaning that it is 0.52 times the first term. The third term is 0.52 times the second term. Thus, in this geometric sequence,

$a = 0.5$
$r = 0.52$

You will need to use the relation $a_n = a \cdot r^(n-1)$
