Help find the value of x pls I’ll give brainleist.

Q: You are shot out of a cannon at the fair. The equation y=-1/5 * (x+2) (x-28) models your flight path, where y is the height above the ground and x is the horizontal distance. Which of the following statements in the comments are true?

a) You reach a maximum height of 45 feet,

b) You will land 11.2 feet from the cannon,

c) The barrel of the cannon is about 11 feet above the ground.

d)At a point 13 feet from the cannon, you begin to descend.

A: When y = 0, x = 28

y’ = 0 at x = 13 where Y is max = 15^2 / 5 = 45

Hence a is true, b is false, c is false, d is false .

Answer:

Here is your answer :

For option ( a )

We know that the longest side of any triangle is its hypotenuse.

So, hypotenuse = 15

Other sides = 9, 12

By Pythagoras Theroem ,

Hypotenuse^2 = Sum of Square of other sides

( 15 )^2 = ( 9 )^2 + ( 12 )^2

225 = 81 + 144

225 = 225

Hence,it can be sides of a right angled triangle.

For option ( b ),

We know that the hypotenuse of a right angled triangle is its longest side.

So, Hypotenuse = √38 = 6√2

Other sides = 2 , 6

By Pythagoras Theroem ,

Hypotenuse^2 = Sum of squares of other sides

( 6√2 )^2 = ( 6 )^2 + ( 2 )^2

72 = 36 + 4

72 ≠ 40

So, it can't be sides of a right angled triangle.

For option ( c )

We know the longest side of any right angled triangle is its hypotenuse.

So, Hypotenuse = √91

Other sides = 3 , 9

By Pythagoras Theroem ,

Hypotenuse^2 = Sum of squares of other sides

( √91 )^2 = ( 3 )^2 + ( 9 )^2

91 = 27 +81

91 ≠ 108

So, it can't be sides of a right angled triangle.

=================================

The final answer is option ( a ).

Step-by-step explanation:

Answer:

A) There is a strong relationship showing that as the number of days increases, the height of the plants increases.

Step-by-step explanation:

Because the correlation coefficient of 0.85 is very close to 1, there's going to be a strong, positive linear correlation between the two variables. Therefore, option A is correct.

There is a strong relationship showing that as the number of days increases, the height of the plants increases.

A correlation coefficient is a bivariate statistic when it summarizes the relationship between two variables, and it’s a multivariate statistic when you have more than two variables.

Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85.

When the correlation coefficient is above 0.8, the correlation cofficeint is strong.

And the function is increasing.

So, there is a strong relationship showing that as the number of days increases, the height of the plants increases.

Hence, there is a strong relationship showing that as the number of days increases, the height of the plants increases.

x is equals to 4 and y is equal to 1

Step-by-step explanation:

3x+3y=9

x-3y=7

elimination method has to do with eliminating one variable from the question to eliminate y we have to add the equations together which is 4x=16

X=4

substitute x is equal to 4 into any equation of your choice let's use equation 1

E

3(4)+3y=9

12+3y=9

12-9=3y

3=3y

divide both sides by 3 therefore y is equal to 1.

500

Step-by-step explanation:

35*12+80

420+80

=500

Answer:

The total cost of the first full year of membership is $500.00.

Step-by-step explanation:

m = per month

x = total cost

Equation: 80 + 35m = x

Since there are 12 months in a year and we want to figure out how much it will cost for the first full year of membership, we will substitute variable m for 12.

80 + 35(12) = x

80 + 420 = 500

Answer:

∠ABC= 82°

∠ACB= 82°

∠BAC= 16°

Step-by-step explanation:

∠ABC +∠ACB +∠BAC = 180° (∠ sum of △ABC)

(5x -3)° +(5x -3)° +(x -1)°= 180°

5x -3 +5x -3 +x -1= 180

11x -7= 180 (simplify)

11x= 180 +7 (+7 on both sides)

11x= 187

x= 187 ÷11

x= 17

∠ABC

= (5x -3)°

= [5(17) -3]°

= 82°

∠ACB

= ∠ABC

= 82°

∠BAC

= (17 -1)°

= 16°

Alternatively,

∠BAC

= 180° -82° -82°

= 16°

Slope = -3/2, y- intercept = 2

Step-by-step explanation:

The y-intercept is 2 because the function touches the y-axis at y=2. The slope is -3/2 because from one point on the axis, you go up 3 points and left 2 points. Slope is rise/run (up/down over left/right)

Answer:

Number of trout caught by Bill = 16 trout

Number of trout caught by Steve = 30 trout

Step-by-step explanation:

Given:

Total number of trout caught = 46

Number of trout caught by Steve = Number of trout caught by Bill + 14

Find:

Number of trout caught by Steve

Number of trout caught by Bill

Computation:

Assume;

Number of trout caught by Bill = a

Number of trout caught by Steve = a + 14

So,

Number of trout caught by Steve + Number of trout caught by Bill = Total number of trout caught

a + a + 14 = 46

2a = 46 - 14

2a = 32

a = 16

Number of trout caught by Bill = 16 trout

Number of trout caught by Steve = a + 14

Number of trout caught by Steve = 16 + 14

Number of trout caught by Steve = 30 trout
