The perimeter of a quadrilateral garden is 4x2+3x-4. The first side is represented by x2+2x+15. The second and third sides are each represented by x2-x-10. What expression represents the fourth side? Write a justification of your result.

Answers

Answer 1

Answer:

[tex]y = x^{2} + 3x + 1[/tex]

Step-by-step explanation:

Perimeter equals the sum of the lengths of the sides.

Let y = the length of the fourth side

[tex]4x^{2} + 3x - 4 = x^{2} + 2x + 15 + x^{2} -x - 10 + x^{2} - x - 10 + y[/tex]

[tex]4x^{2} + 3x - 4 = 3x^{2} - 5 + y[/tex]

[tex]x^{2} + 3x + 1 = y[/tex]

please help me with this slope problem! :) (brainliest)

Answers

Answer:

Plot these points

(1,935)

(2,870)

(3,805)

(4,740)

(5,675)

Slope= -65

y intercept = 1000

and what it's saying is that we travel at a speed of 65 units an hour and we start 1000 miles away

Step-by-step explanation:

Just graph these points which you can get by plugging in the numbers

1000-65= 935

(1,935)

1000-65*2=870

(2,870)

1000-65*3= 805

(3,805)

1000-65*4=740

(4,740)

1000-65*5= 675

(5,675)

B:

y= mx+b where m is the slope and B is the y intercept

we can re write the equation as follows

-65x+1000

It's pretty clear that -65 is the slope and 1000 is the y intercept

Step-by-step explanation:

Answer:

i. 1/4

ii. 54/125

iii. 1107/5000000

iv. 1/50

Step-by-step explanation:

i.

25% = 0.25

0.25 = 25/100

25/100 (GCF 25) = 1/4

ii.

43.2% = 0.432

0.432 = 432/1000

432/1000 (GCF 8) = 54/125

iii.

0.02214% = 0.0002214

0.0002214 = 2214/10000000

2214/10000000 (GCF 2) = 1157/5000000

find the length of the arc intercepted by a central angle of 1.5 radians in a circle of radius 9 cm.

Answers

Answer:

13.5 cm

Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), and the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:

L/θ = C/2π (C = Circumference = 2πr)

L/θ = 2πr/2π,

L/θ = r,

L = r*θ = 9 cm * 1.5 = 13.5 cm

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the expression -

5(x + 8)

We can write the equivalent expression for the given function is -

y = 5(x + 8)

y = 5x + 40

Therefore, the equivalent expression for the given function is -

y = 5x + 40.
