Answer:

C. two

Step-by-step explanation:

2 points of intersection

Option C is correct, there are two solutions to the nonlinear system of equations graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A system of nonlinear equations is a system of two or more equations in two or more variables containing at least one equation that is not linear.

In this case, we have a parabola (the red figure) and a line (the blue figure).

There are three possible types of solutions for a system of nonlinear equations involving a parabola and a line.

No solution. The line will never intersect the parabola.

One solution. The line is tangent to the parabola and intersects the parabola at exactly one point.

Two solutions. The line crosses on the inside of the parabola and intersects the parabola at two points.

Hence, there are two solutions to the nonlinear system of equations graph.

Answer:

I think it is 20 < x > 9. But I am not completely sure.

Answer:

The slope is 2

Step-by-step explanation:

Given

[tex](x_1,y_1) = (2,9)[/tex]

[tex](x_2,y_2) = (-1,3)[/tex]

The slope (m)

This is calculated as:

Answer:

0.28 represents the growth factor

Step-by-step explanation:

Given

[tex]f(x) = 5719(0.28)^x[/tex]

Required

What does 0.28 represents

In a function:

[tex]y = ab^x[/tex]

b represents the growth factor.

By comparison:

[tex]b = 0.28[/tex]

Answer:

11. CK = 66

12. QS = 72

13. CE = 11

14. LJ = 60

Step-by-step explanation:

Recall: the corresponding side lengths of similar triangles are proportional and the ratio of their side lengths are equal.

11. AB/KL = AC/KC

77/42 = 121/CK (Substitution)

Cross multiply

77*CK = 121*42

77*CK = 5082

CK = 5082/77

CK = 66

12. QR/BQ = QS/CQ

72/32 = (32 + CS)/32 (Substitution)

Cross multiply

32(32 + CS) = 72*32

1024 + 32*CS = 2304

32*CS = 2304 - 1024

32*CS = 1280

CS = 1280/32

CS = 40

QS = 32 + CS = 32 + 40 = 72

13. QS/CE = QR/CD

33/CE = 36/12

33/CE = 3

Cross multiply

3*CE = 33

Divide both sides by 3

CE = 33/3

CE = 11

14. LJ/LU = LK/LV

LJ/10 = 60/10

LJ/10 = 6

LJ = 6*10

LJ = 60

Step-by-step explanation: Just divide

Answer:

Explanation:

1) The two parallel sides of different legths 1\frac{3}{4}143 and 1\frac{1}{4}141 constitute the bases of a trapezoid.

2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.

An isosceles trapezoid is truncated isosceles triangle.

The definition of trapezoid is a quadrilateral with at least two parallel sides.

The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.

Answer:Mark Is 9 years old; Christine is 5 years old

Step-by-step explanation:

Present age

LET  mark age be x

Christine be x-4 yrs

In 3 yrs Time

Mark will be x+3 yrs old

Christine  will be  (x -4 +3) = x-1 years old

Also, In 3 years time

Christine  = 2/3 Mark

such that

  x-1 = 2/3(x+3)

  x -1= 2x+6 / 3

    3x  -3= 2x+6

      3X--2X = 6+3

         =X=9

Mark Is 9 years old

Christine is   x -4 = 9-4=5 years old

Answer:

Step-by-step explanation:

Answer:

12

Explaination:

12 times 5 is 60

Answer:

a) The relative risk is 1.8[tex]\overline{846153}[/tex]

b) The attributable risk is [tex]0.69 \overline{047619}[/tex]

c) There is a relationship between exposure and tumor risk

Step-by-step explanation:

The number of exposed rats that develop tumors, a = 42

The number of rats exposed to the carcinogen = 600 rats

The number of exposed rats that did not develop tumors, b = 600 - 42 = 558

The number of not exposed rats in the control group = 350 rats

The number of rats that develop tumors in the control group, c = 13 tumors

The number of not exposed rats that did not develop tumors, d = 350 - 13 = 337  rats

a) The relative risk, RR = a/(a + b)/(c/(c + d))

∴ RR = (42/(42 + 558))/(13/(13 + 337)) = 49/26 = 1.8[tex]\overline{846153}[/tex]

b) The attributable risk = (a - c)/a

∴ The attributable risk = (42 - 13)/42 = [tex]0.69 \overline{047619}[/tex]

c) The odds ratio = (a·b)/(c·d)

∴ The odds ratio = 42 × 558/(13 × 337) = 23439/4381 ≈ 5.35

Given that the result of attributable risk is positive, there is an indication that there is a higher probability to develop tumor when exposed to the potential carcinogen, therefore, there is a relationship between exposure and tumor risk

Answer:

Quintrell's number is 9.

Step-by-step explanation:

Let [tex]x[/tex] be equal to Quintrell's number.

"When 35 is added to my number, the answer is 4 times my original number plus 8."

⇒

[tex]35+x=4x+8[/tex]

Subtract both sides by [tex]x[/tex]

[tex]35+x-x=4x+8-x\\35=3x+8[/tex]

Subtract both sides by 8

[tex]35-8=3x+8-8\\27=3x[/tex]

Divide both sides by 3

[tex]\frac{27}{3} =\frac{3x}{3} \\9=x[/tex]

Therefore, Quintrell's number is 9.
