The roots of the equation is 1 and 3.28

The given equation is a quadratic

To find the roots of a quadratic equation, the formula is

[tex]\frac{-b + \sqrt{b^{2} - 4ac } }{2a}[/tex]

The equation is 101x^2+231x-334=-2  we need to find the A,B,C

101x^2+231x-332 = 0

here a is 101, b is 231, and c is -332

[tex]\frac{-b + \sqrt{b^{2} - 4ac } }{2a}\\\frac{-231 + \sqrt{231^{2} - 4(101)(-332) } }{2(101)}\\\frac{-231 + \sqrt{53361 + 134128 } }{202}\\\frac{-231 + \sqrt{187489 } }{202}\\\\\frac{-231 + \sqrt{187489 } }{202}\\\\\frac{-231 + 433 }{202}\\\\=\frac{202}{202}\\\\ 1[/tex]

[tex]\frac{-b - \sqrt{b^{2} - 4ac } }{2a}\\\frac{-231 - \sqrt{231^{2} - 4(101)(-332) } }{2(101)}\\\frac{-231 - \sqrt{53361 + 134128 } }{202}\\\frac{-231 - \sqrt{187489 } }{202}\\\\\frac{-231 - \sqrt{187489 } }{202}\\\\\frac{-231 -433 }{202}\\\\=\frac{664}{202}\\\\ 3.28[/tex]

Therefore, the roots of the equation is 1 and 3.28

The length of the guy wire, to the nearest foot is 1548 ft.

The right-angled triangle's relationship between its three sides is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The square of a triangle's hypotenuse is equal to the sum of its other two sides' squares, according to the Pythagoras theorem. The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC² = AB² + AC² in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized

After sketching the information given, we have two similar right triangles, ΔABE and ΔCDE.

CD = 6 ft

DE = 1 ft

BD = 12 ft

Since ΔABE ~ ΔCDE, therefore,

AB/CD = BE/DE (proportional sides)

Plug in the values

AB/6 = (12 + 1)/2

AB/6 = 13/2

Cross multiply

AB = 13(3)

AB = 39 ft

AE = √(AB² + BE²)

AE = √(39² + 12²)

AE = 1548 ft (nearest foot)

Step-by-step explanation:

Answer:

x > -2

Step-by-step explanation:

The student needs a minimum score of 956 to stay in the top 15% of the normal distribution.

Normal distributions are fundamental to statistics because they are widely used in the social and natural sciences to represent real-valued regressors with uncertain distributions.

Now top 15%

Therefore P=0.15

P(X<x) = 1 -0.15 = 0.85

Z-score = 1.04

Now we know that

z=(x-μ)/σ

Solving we get :

1.04 = (x - 800)/150

or, x = 956

hence the minimum score is 956.

The amount of money that Susie makes for 7 working days will be;

⇒ $314.3

What is mean by Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Susie has a part-time job at the video store and she makes between $41.89 and $47.91 a day.

Now,

The amount of money for a day = ($41.89 + $47.91) / 2

The amount of money for a day = $89.8 / 2

The amount of money for a day = $44.9

Thus, The amount of money that Susie makes for 7 working days is;

= 7  x $44.9

= $314.3

Hence,

The amount of money that Susie makes for 7 working days will be;

Answer:

y = (1/4)x - 5

Step-by-step explanation:

We'll look for an equation having the form y=mx+b, where m is the slope and b is the y-intercept, the value of y when x=0.

We are told the slope, m, is (1/4):

  y = (1/4)x+ b

We need to find a value of b such that it forces the line to go through point (8,-3).  Enter that point in the equation:

  y = (1/4)x + b

  -3 = (1/4)(8) + b    for (8,-3)

   -3 = 2 + b

b = -5

The equation is y = (1/4)x - 5

The probability the friend finds no one in the first spot is 60%.

Probability is the chance or likelihood that an expected event occurs when there are many possible outcomes or events.

For instance, the probability that when the counting friend goes to the hiding spot, they can or cannot find a friend there.

The two friends can only hide in 2 spots, leaving 3 spots with nobody.

The number of hiding spots = 5

The number of friends hiding = 2

The number of counting friends = 1

The number of spots they can hide = 2 out of 5

The probability of finding a person in a hiding spot = 2/5 or 40%

The probability of not finding a person in a hiding spot = 3/5 (1 - 2/5) or 60% (1 - 40%).

The chances that your friend finds anyone in the first spot are 60%.

The number of outcomes that do not show c is calculated to be 9 if each spinner is spun once.

The three possible outcomes of the first spinner are 1,2 and 4 and the possible outcomes of the second spinner are a,b,c and d; so if the two spinners are spun together, the possible outcome will be:

a1, a2, a4

b1, b2, b4

c1, c2, c4

d1, d2, d4

Therefore, there are a total of 12 possible outcomes, and 3 out of these possible outcomes show c. Now the outcomes that do not show c can be calculated by subtraction as follows;

Outcome not showing c = Total outcomes - Outcomes showing c

Outcome not showing c = 12 - 3

Outcome not showing c = 9

Answer: 6

Step-by-step explanation:

The point R represents the number -2.5 on the number line

From the question, we understand that the point R is halfway between the integers on the number line

This means that

Point R = 1/2 * (a + b)

Where variables a and b represent the boundaries of the integers

In this case, we have

a =-2

b = -3

Substitute a =-2 and b = -3 in the equation Point R = 1/2 * (a + b)

So, we have

Point R = 1/2 * (-2 - 3)

Evaluate the difference

Point R = 1/2 * -5

Evaluate the product

Point R = -2.5

Hence, the location of R on the number line is  -2.5

The relationship between the graph of f(h) and graph of g(h)

A graph is a pictorial representation of information

The difference in the two graphs is the part of the non refundable deposit which will affect the intercept.

In f(h) = 8h + 10, the non refundable deposit 10 and the increment is 15%

The increment is solved below

solving the percentage increased

15% of $10 = 0.15 * 10 = $1.5

adding to the initial deposit

10 + 1.5 = 11.5

g(h) = 8h + 11.5

The graph of g(h) will have same slope as graph of f(h) which is 8

The y intercept of the graph if g(h) will be 11.5 while that of the graph of f(h) is 10
