Step-by-step explanation:

The point on the parabolic equation y = -x² + 4x + 1 and line y = -x + 5 intersect is P ( 4 , 1 ) and Q ( 6 , -1)

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

y = a ( x - h )² + k

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

Let the parabolic equation be y = -x² + 4x + 1

Let the equation of line be y = -x + 5

Now , To find the points of intersection between the parabola y = -x² + 4x + 1 and the line y = -x + 5, we need to set the two equations equal to each other and solve for x and y simultaneously.

Setting y = -x² + 4x + 1 equal to y = -x + 5, we get:

-x² + 4x + 1 = -x + 5

Rearranging the equation, we get a quadratic equation in standard form:

-x² + 4x + x - 1 - 5 = 0

-x² + 5x - 6 = 0

Factoring the quadratic equation, we get:

-(x - 1)(x - 6) = 0

Setting each factor equal to zero and solving for x, we get two potential values for x:

x - 1 = 0 or x - 6 = 0

x = 1 or x = 6

Now, substituting the values of x back into the equation y = -x + 5 to find the corresponding y-values, we get:

For x = 1:

y = -1 + 5

y = 4

So, one point of intersection is (1, 4)

For x = 6:

y = -6 + 5

y = -1

So, the other point of intersection is (6, -1).

Hence , the point of intersection is P ( 4 , 1 ) and Q ( 6 , -1)

Step-by-step explanation:

3+5=8

160÷8= 20

20× 5=100

20×3=60

100-60=40

Answer:

£40

Step-by-step explanation:

160 shared between 3:5

3 + 5 = 8 (parts)

160 ÷ 8 = 20

20 = 1 part

Sue has 3 parts; (20 x 3) = £60

Oliver has 5 parts; (20 x 5) = £100

Work out how much more oliver get conpared to sue

oliver has £100, sue has £60

£100 - £60 = £40

oliver has £40 compared to sue

The y-intercept is the required point and its coordinates are (0, 7)

Answer:

You can use the definite integral to find the volume of a solid with specific cross sections on an interval, provided you know a formula for the region determined by each cross section. If the cross sections generated are perpendicular to the x‐axis, then their areas will be functions of x, denoted by A(x). The volume ( V) of the solid on the interval [ a, b] is

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the number line is not given. The general explanation is as follows;

First, record the time she hung up (say, time = x)

To rewind 15 minutes back means, x - 15

So, point on the number line will be x - 15

Take for instance

[tex]x = 45[/tex]

The point on the number line will be:

[tex]x - 15 = 45 - 15[/tex]

[tex]x - 15 = 30[/tex]

Answer:

x = 16

Step-by-step explanation:

The given angles are alternate angles and are congruent , then]

10x - 23 = 137 ( add 23 to both sides )

10x = 160 ( divide both sides by 10 )

x = 16

This is a classic proof of the Pythagorean Theorem!

Pythagorean theorem is a^2 + b^2 = c^2. With a square, its area is its side length squared. Therefore, if we think about this as squares, then the sum of the area of square X and square Y will be equal to the sum of square Z.

Looking at your answer choices, the best option is C - The number of tiles needed to cover Region Z is the same number of tiles needed to cover both Region X and Region Y.

Answer:

n = 12.5t

Step-by-step explanation:

add up the calories burned in both days

275 + 450 = 725

add up the minutes running on both days

22 + 36 = 58

divide calories by minutes

725 calories/58 minutes = 12.5 calories/1 minute

So 12.5 multiplied by any number of minutes tells you how many calories you burned

The number of calories you burned is dependent on the number of minutes you ran.

Answer: 2 ounces

Step-by-step explanation:

Since Juan and Bill share a 12-ounce bucket of clay and Juan used 1/6 of the bucket, the quantity used by Juan will be:

= 1/6 × 12

= 2 ounce bucket of clay.

On the other hand, Bill used 2/3 of the bucket of clay. The quantity used will be:

= 2/3 × 12

= 8 ounce

Therefore, the quantity they both used will be:

= 2 ounce + 8 ounce

= 10 ounces.

The ounces left in the bucket will be:

= 12 ounces - 10 ounces

= 2 ounces
