Patel is solving 8x2 + 16x + 3 = 0. Which steps could he use to solve the quadratic equation? Select three options. (PLEASE HELP!!!)

Answer:

D. 16

Step-by-step explanation:

A quality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results:

MACHINE MEASUREMENTS

#1 17 15 15 17

#2 16 25 18 25

#3 23 24 23 22

Answer:

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & {14} & {26} & {36} & {44} & {50}\ \end{array}[/tex]

Step-by-step explanation:

Given

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & { } & { } & { } & { } & {50}\ \end{array}[/tex]

Required

Complete the table of Areas

Using the complete column:

Where x = 5, y = 10 and A = 50,

We can deduce that, the area is calculated as:

[tex]A = 5 * 10 = 50[/tex]

i.e.

[tex]A = x * y[/tex]

So, for other values of x and y, the area is calculated as thus:

[tex]x = 1; y = 14[/tex]

[tex]A = 1 * 14 = 14[/tex]

[tex]x = 2; y = 13[/tex]

[tex]A = 2 * 13 = 26[/tex]

[tex]x = 3; y=12[/tex]

[tex]A = 3 * 12 = 36[/tex]

[tex]x =4;y =11[/tex]

[tex]A = 4 * 11 = 44[/tex]

So, the complete table is:

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & {14} & {26} & {36} & {44} & {50}\ \end{array}[/tex]

Step-by-step explanation:

7% of $45 is 3.15 so you would add 3.15 to $45 to get $48.15

Answer:

x ≈ 3.29

Step-by-step explanation:

Take the logarithm of both sides of the equation to remove the variable from the exponent.

Exact Form:

x  = [tex]\frac{ln(200)}{ln(5)}[/tex]

Decimal Form:

x  =  3.29202967 … ≈ 3.29 (Round to what the question asks, in this case, I rounded to 2 decimal places)

Answer:

ln200/ln5

Step-by-step explanation:

ln5^x=ln200

xln5=ln200

x=ln200/ln5

Answer:

[tex]\frac{3}{2}i + \frac{3\sqrt{3} }{2}[/tex]j

Step-by-step explanation:

The work done by the force in moving the object is 10 ft-lb.

Force is an influence or interaction that can change the motion or shape of an object with mass.

It can be described as a push or a pull that has both magnitude and direction.

Force is equal to the product of the mass of the object and its acceleration.

Given,

F = 3 p

d = 4 ft

The work formula:  

W = F x d

W = 4 p x cos 60° x 5 ft

= 10 ft lb.

Hence, the work done by the force in moving the object is 10 ft-lb.

Step-by-step explanation:

The length of the altitude of the equilateral triangle is a√3/4 units.

Given is to find the length of the altitude of the equilateral triangle.

An equilateral triangle is a triangle whose all sides are equal. All the angles of a given equilateral triangle are 60 degrees.

The length of the altitude of the equilateral triangle can be found out using the Pythagoras theorem.

Draw a median from one vertex on the opposite side to that vertex and apply Pythagoras theorem to one of the right triangle.

We can find the length of the altitude to be -

L = a√3/4

Therefore, the length of the altitude of the equilateral triangle is a√3/4 units.

Mexican Gulf Output of a Oil-Rig

Based on 57% red flag days, Joe, the retired statistician, who watches from the shore for the red flag every day, cannot conclude that the oil-rig is operating at a non-ideal condition most of the time, but more of the time.

Step-by-step explanation:

Ideal output of a particular oil-rig, at least = 2,000 barrels per day

When output is lesser than 2,000, a red flag is raised by the foreman

Number of days counted = 28

Number of days when red flag was raised = 16

Proportion of days when the red flag was raised = 16/28

= 0.57

or 57%

Answer:

1. VW = 22

2. x = 87

Step-by-step explanation:

Question 1:

SU = 11 (given)

SU = ½(VW) => midsegment theorem

11 = ½(VW) => Substitution

Multiply both sides by 2

2*11 = VW

VW = 22

Question 2:

UV = x + 13

RT = x - 37

RT = ½(UV) => Midsegment Theorem

x - 37 = ½(x + 13) => Substitution

Multiply both sides by 2

2(x - 37) = x + 13

2x - 74 = x + 13

2x - 74 + 74 = x + 13 + 74

2x = x + 87

2x - x = x + 87 - x

x = 87

Answer:

x = 45

Step-by-step explanation:

0.36(18) + 0.04x = 0.12(24 + x)

6.48 + 0.04x = 2.88 + 0.12x

0.04x - 0.12x = 2.88 - 6.48

-0.08x = -3.6

0.08x = 3.6

x = 3.6/0.08

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

[tex]h = -16x^2 + 16x[/tex]

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

[tex]-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1[/tex]

So, it will touch the ground at x = 0 and x = 1 seconds.
