Answer:

Graph A: two distinct roots.  Graph B: one repeated real root. Graph C: two complex roots. Graph D: two distinct real roots.

Step-by-step explanation:

Explanation:

Each graph represents a quadratic function. So by the fundamental theorem of algebra, we know that each graph will have two roots.

Graph A crosses the x-axis twice. So, graph A has two distinct real roots.

Graph B touches the x-axis once. A quadratic cannot have one real root and one complex root. So it must have one repeated real root.

Graph C doesn’t cross the x-axis. This means it must have two complex roots.

Graph D crosses the x-axis twice. So, graph D has two distinct real roots.

B. 5 shirts were bought and the total was $110

C. 4

Step-by-step explanation:

A.

For every 1 increase in the x variable(the first number) the y variable(the second number) increases by 22

B.

The pair represents that he got 5 shirts and that he paid $110. you can check your work by seeing that if yoiu divide 110 by 5 you get the price of the t-shirt; $22

C.

If each shirt is $22 you divide $88 by $22 and get the amount of t-shirts bought; 4

Step-by-step explanation:

Hello,

Hôpital's rule will help here.

[tex]\forall t \in \mathbb{R}^*\\\\f(t)=1-cos(2t)\text{ *** f is differentiable}\\f'(t)=2sin(2t)\\f''(t)=4cost(2t)\\f''(0)=4 \\ \\g(t)=sin^2(11t)\text{ *** g is differentiable}\\g'(t)=2sin(11t)\times 11 \times cos(11t)=2\times 11 sin(11t)cos(11t)\\\\g''(t)=2\times 11 (11cos^2(11t)-11sin^2(11t))\\g''(0)=2\times 11^2[/tex]

So the limit is 4/(2*121)=2/121

Answer:

m∠1 = 25°

Step-by-step explanation:

Sum of Angles in a triangle: 180°

Degree of measure of a line: 180°

Step 1: Find missing angle ∠2

m∠2 + 104 = 180

m∠2 = 76°

Step 2: Find missing angle ∠1

m∠1 + m∠2 + 79 = 180

m∠1 + 76 + 79 = 180

m∠1 + 155 = 180

m∠1 = 25°

Answer:

C. 0.55

Step-by-step explanation:

The scatter plot shows that there is a positive correlation between variable x and variable y. This is because, the x and y variable seem to follow the same trend. That is, as x variable increases, y variable also increases. If a line of best fit is drawn, it would slope upwards, from left to our right.

Correlation coefficient (r) of any given data set plotted on a scatter plot, ranges from -1 to 1. The closer the value of "r" to either -1 or 1, the more clustered the data points are together in a line of best fit in a scatter plot.

Therefore, since the scatter plot given shows a positive relation between the x and y variables, whereby the data points seem to be less clustered and farther from each away from the line if best fit, if drawn, an estimate of "r" would not be closer to the value of 1.

Therefore, from the options given, C. 0.55 is the best estimate for r for the data shown in the scatter plot.

Step-by-step explanation:

As we can see in the picture, the bigger pentagon is a scale copy of the smaller one with a scale factor of 2. Hence, all the sides on the smaller pentagon multiplied by 2 gives us the bigger pentagon. We can find the scale factor by looking at the biggest side of the pentagon. Hope this helped, Thank you.

Answer:

The classification of the set of circumstances is presented in the following subsections of the understanding.

Step-by-step explanation:

A 7-year health research project revealed that individuals for whom the mom took DES throughout pregnancy seem to have been twice as probable as women for whom the mothers didn't use the medication to establish tissue irregularities that could cause cancer.  

(a)

Women with whom the mothers have taken DES throughout pregnancy as well as women where its mothers haven't taken DES during pregnancy.

(b)

The information collected seems to have been a sample or survey.  

(c)

A sampling unit of 3980 (women) showed that performance 63 industrialized tissue irregularities that could contribute to disease (cancer) in the proportion of females with whom the mom brought the powerful DES all through pregnancy.  

The proportion of abnormalities in tissues established by females does seem to be:  

=  [tex]\frac{63}{3980}[/tex]

=  [tex]0.015829[/tex]

Of every thousand women, 15.8 established tissue abnormalities.

There are 3 terriers

Step-by-step explanation:

3 terriers * 5 = 15 yellow labs

15 yellow labs + 3 terriers = 18 dogs

Given :

A particle moves in the xy plane starting from time = 0 second and position (1m, 2m) with a velocity of v=2i-4tj  .

To Find :

A. The vector position of the particle at any time t .

B. The acceleration of the particle at any time t .

Solution :

A )

Position of vector v is given by :

[tex]d=\int\limits {v} \, dt\\\\d=\int\limits {(2i-4tj)} \, dt \\\\d=(2t)i+\dfrac{4t^2}{2}j\\\\d=(2t)i+(2t^2)j[/tex]

B )

Acceleration a is given by :

[tex]a=\dfrac{dv}{dt}\\\\a=\dfrac{2i-4tj}{dt}\\\\a=\dfrac{2i}{dt}-\dfrac{4tj}{dt}\\\\a=0-4j\\\\a=-4j[/tex]

Hence , this is the required solution .

40. No, X=-2.4

Step-by-step explanation:

Explanation for 40:

2(x-4)-4x=-6x+9x+4

first do the parentheses

2x-8-4x=-6x+9x+4

next combine like terms

-2x-8=3x+4

add 2x to each side

-8=5x+4

subtract 4 from each side

-12=5x

divide both sides by 5

x=-2.4

Answer:

First off you have to start with what you know. You know the two planes cost 7.95 and you know the total is 24.65

Then to find the price of the stickers you subtract the 7.95 from  24.65=16.70

So your equation to start is

7.95+x=24.65

Subtract 7.95 from both sides

x=16.7-

Step-by-step explanation:

If she had 17 dollars left at the end, subtract that from the total amount she had. 105-17= 88. Then youdevide 88 by 8 (because she got 8 books) and yu get 11

Answer:

120 yards 1.

Step-by-step explanation:

In the shape, it is a rectangle with a triangle cut out from it. What is the area of the shape:

Area of rectangle = length × width

12 × 15 = 180 yards²

Area of triangle = ½ × base × height

½ × 10 × 12 = 60 yards²

Now subtract the area of triangle from the area of rectangle:

180 - 60 = 120 yards ²

Answer:

A. 3

Step-by-step explanation:

Given,

[tex] BC = x + 15 [/tex],

[tex] AC = 14 [/tex]

[tex] AB = x + 7 [/tex], since A, B, and C are collinear, therefore, based on the segment addition postulate:

[tex] AB + BC = AC [/tex].

Thus, substituting the values into the equation, we have:

[tex] (x + 7) + (x + 15) = 14 [/tex]

Solve for x.

[tex] x + 7 + x + 15 = 14 [/tex]

[tex] 2x + 22 = 14 [/tex]

Subtract 22 from both sides

[tex] 2x = - 8 [/tex]

Divide both sides by 2

[tex] x = -4 [/tex]

[tex] AB = x + 7 [/tex]

Plug in the value of x

[tex] AB = -4 + 7 = 3 [/tex],

Answer:

Answer:

A) 0.005

B) 0.001

C)0.0495

Step-by-step explanation:

Let A be the event that an aircraft is present and let B be the event the radar registers its presence.. Thus;

P(A) = Probability that an aircraft is present

P(A') = Probability that an aircraft is not present

P(B) = Probability that the radar generates an alarm

P(B') = Probability that the radar doesn't generate an alarm

Thus from what we are given, we have;

P(A) = 0.05

P(A') = 0.95

P(B) = 0.99

P(B') = 0.01

P(B|A') = 0.1

A) Probability of a false alarm will be;

P(A' ∩ B) = P(A) × P(B|A')

P(A' ∩ B) = 0.05 × 0.1 = 0.005

B) probability of missed detection is;

0.1 × (1 - 0.99) = 0.001

C) probability that an aircraft is present given that the radar registers a presence will be;

P(A ∩ B) = P(A) × P(B)

P(A ∩ B) = 0.05 × 0.99

P(A ∩ B) = 0.0495

Step-by-step explanation:

Answer:

Trinomial

Step-by-step explanation:

Step-by-step explanation:

All u have to is subject t from that formula.

D=C( 1 + rt/100)

D/C = 1+ rt/100

D/C - 1 = rt/100

So,

When u multiply the equation by 100 and divide by r it will be as follows.

(D/C -1)100/r = t

It is the answer C.

And now to get the answer E,

we have the equation as t = (D/C-1) 100/r

First solve what inside the bracket.

D/C - 1

D/C - C/C

(D-C)/C

So when u put that to the above,

t= (D-C/C) 100/r

Now all u have to do is just multiply

t= 100(D-C) / Cr

Use this formula:

slope = (y₂ - y₁) / (x₂ - x₁)

= (-8 - (-6)) / (2 - 5)

= (-2) / (-3)

= 2/3
