4 > 2p

2 > p

Some answers are p = 1, p = 0, p = -1, etc.

Answer:

A. f(x); (2, 0)

Step-by-step explanation:

First, we determine the zeros of f(x)

[tex]f(x)= 2x^2 - 14x + 20=0\\2(x^2 - 7x + 10)=0\\x^2 - 7x + 10=0\\x^2-5x-2x+10=0\\x(x-5)-2(x-5)=0\\(x-5)(x-2)=0\\x-5=0$ or x-2=0\\x=5 or x=2[/tex]

The zeroes of f(x) are 5 and 2.

We can then conclude that f(x) is the function which has the smallest zero.

Its coordinate is (2,0).

Step-by-step explanation:

=> [tex]4^3[/tex]

=> 4 × 4 × 4

=> 64

Answer:

4 times 4 times 4 = 64

Step-by-step explanation:

When a number is cubed, it is multiplied by itself 3 times.

For example, [tex]x^3=x*x*x[/tex].

In our case, it is [tex]4^3=4*4*4[/tex] which would equal [tex]16*4=64[/tex]

Your answer is "4 times 4 times 4 = 64"

Answer:

y = 3x - 10

Step-by-step explanation:

Step 1: Rewrite 1st equation

2y = 6x + 4

y = 3x + 4

Step 2: Find 2nd equation

y = 3x + b

-4 = 3(2) + b

-4 = 6 + b

b = -10

Step 3: Rewrite 2nd equation

y = 3x - 10

And we have your parallel equation!

Answer:

Step-by-step explanation:

Known fact: all roots of quadratic equation [tex]ax^2 + bx + c = 0[/tex] are real if and only if

discriminant [tex]D = b^2 - 4ac \geq 0.[/tex]

We know that all roots of [tex]x^2 + px + q = 0[/tex] are real. We can derive from this condition that

[tex]p^2 - 4q \geq 0[/tex]. (<----------- HERE)

Let's do some simplification of second equation:

[tex]x^2 + px +q + (x + a)(2x + p) = 3x^2 + x(2p + 2a) + ap + q.[/tex]

So we want according to Known fact prove that discriminant of equation

[tex]3x^2 + x(2p + 2a) + ap + q = 0[/tex] is greater or equal zero.

[tex]D = (2p + 2a)^2 - 4\cdot 3 (ap + q) = 4(p^2 + a^2 + 2ap - 3ap - 3q) = 4(a^2 - ap + p^2 - 3q)[/tex].

To prove that [tex]D \geq 0[/tex], we can view D as polynomial of a:

[tex]D(a) = 4a^2 - a(4p) + 4(p^2 - 3q)[/tex].

Known fact #2: if quadratic polynomial have positive greatest coefficient and it's discriminant [tex]\leq 0[/tex] then polynomial always positive.

So remains to prove that

[tex](4p)^2 - 4\cdot 4\cdot 4(p^2 - 3q) \leq 0[/tex]  

lets divide both side by [tex]4^2[/tex]:

[tex]p^2 - 4(p^2 - 3q) \leq 0[/tex]

[tex]-3p^2 + 12q \leq 0[/tex]

divide by 3

[tex]-p^2 + 4q \leq 0[/tex]

transfer terms to the other side:

[tex]0 \leq p^2 - 4q[/tex]

But we know that from "(<----------- HERE)"!!!

So Q.E.D.

Answer:

cosA = 40/41

tanA = 9/40

Step-by-step explanation:

Step 1: Find the other leg value

a² + b² = c²

9² + b² = 41²

b² = 41² - 9²

b = √1600

b = 40

Step 2: Draw out your triangle.

When you do so, you should see the cosA (adjacent over hypotenuse) is 40/41 and tanA (opposite over adjacent) is 9/40.

Triangle CBA

Length of AC = 40 (Leg)

Length of BC = 9 (Leg)

Length of AD = 41 (Hypotenuse)

cosA = AC/AB = 40/41

tanA = CB/AC = 9/40

Answer:

Cos A = 40/41

Tan A = 9/40

Step-by-step explanation:

Sin A = [tex]\frac{perpendicular}{hypotenuse}[/tex] = [tex]\frac{9}{41}[/tex]

So,

Perpendicular = 9 , Hypotenuse = 41

So, Finding base by Pythagorean Theorem

=> [tex]c^2=a^2+b^2[/tex]

=> [tex]a^2 = c^2-b^2\\[/tex]

=> [tex]a^2 = 41^2-9^2[/tex]

=> [tex]a^2 = 1681 - 81\\a^2 = 1600[/tex]

Taking sqrt

=> base = 40

Now,

Cos A = [tex]\frac{base}{hypotenuse} = \frac{40}{41}[/tex]

Tan A = [tex]\frac{perpendicular}{base} = \frac{9}{40}[/tex]

Answer:

y = 7 [tex]3^{x}[/tex]

Step-by-step explanation:

Use the given ordered pairs to find a and b

Using (0, 7 ), then

7 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), thus

a = 7

y = 7 [tex]b^{x}[/tex]

Using (5, 1701 )

1701 = 7 [tex]b^{5}[/tex] ( divide both sides by 7 )

243 = [tex]b^{5}[/tex] ( take the fifth root of both sides )

b = [tex]\sqrt[5]{243}[/tex] = 3 , thus

y = 7 [tex]3^{x}[/tex]

Answer: d) 576

Step-by-step explanation:

Datos:  

El perímetro de un rectángulo es igual a la suma de todos sus lados:  

Perímetro = 2h+2b  

Reemplazando b=4h

120 =2h+ 2(4h)  

Despejando h:

120 = 2h+8h  

120 =10h  

120/10=h  

12 cm=h  

Base = 4h =4(12) =48 cm

Answer: C

Step-by-step explanation:

IT is dividing by 6

The value of x in the given diagram of two similar triangle is  9 units.

Let us consider the name of two triangles be ABC and PQR.

Such that,

In triangle ABC,

AB = 12 , BC = 54 , m∠BAC = 90° and marked angle  is ∠ABC .

In triangle PQR,

PQ = 2 , QR = x, m∠QPR = 90° and marked angle  is ∠PQR .

In triangle ABC and PQR we have,

m∠BAC = 90° = m∠QPR

m∠ABC = m∠PQR  (given )

By AA corollary,

Triangle ABC is similar to triangle PQR with correspondence ABC ↔ PQR.

Corresponding sides of the similar triangle are in proportion.

AB / PQ = BC / QR

⇒ 12 / 2 = 54 / x

⇒ 12x  = 54 × 2

⇒ x = ( 54 × 2 ) / 12

⇒ x = 9

Therefore, the value of x in the given triangle is equal to 9 units.

Answer:

  2

Step-by-step explanation:

The given angle is opposite the shortest of the given sides, and sin(A) < 5/6, so there are two possible solutions.

The law of sines tells you that angle C will satisfy ...

  sin(C)/ab = sin(A)/bc

  sin(C) = ab/bc·sin(A) = 6/5·1/2 = 3/5

The given angle is 30°, so the sum of remaining angles must be less than 150°. There are two possible angles less than 150° that have a sine of 3/5:

  C₁ = arcsin(3/5) = 36.87°

  C₂ = 180° -arcsin(3/5) = 143.13°

You can construct two triangles with the given measurements.

Answer:

0.35

Step-by-step explanation:

This probability distribution is shown below:

Pitch                   1            2        3          4         5

Frequency         15         20      40        15        10

Probability         0.15     0.2      0.4      0.15      0.1

The probability that the pitcher will throw fewer than 3 pitches to a batter = P(X < 3)

X  is the number of pitches thrown. Therefore:

P(X < 3) = P(X = 1) or P(X = 2)

The additive rule pf probability states that if two events X and Y are dependent events, the probability of X or Y occurring is the sum of their individual probability.

P(X < 3) = P(X = 1) or P(X = 2) = P(X = 1) + P(X = 2) = 0.15 + 0.2 = 0.35

The probability that the pitcher will throw fewer than 3 pitches to a batter = 0.35

Answer:

n = 2

Step-by-step explanation:

Expand the brackets.

1/2n - 2 - 3 = 3 - 2n - 3

Add or subtract terms.

1/2n - 5 = -2n

Add 5 and 2n on both sides.

1/2n + 2n = 5

5/2n = 5

Multiply both sides by 2/5.

n = 5 × 2/5

n = 10/5

n = 2

Answer:

x+56°= 2x

x= 56°

2x= 112°

Answer: Participants were lead to respond in a specific way.

Step-by-step explanation: Bias is an inherent misjudgment about something. Often, this can mean that the wording of the question leads the participants to respond in a specific way.

The statement "a statistical study is biased" means (D) Participants were led to respond in a specific way.

An event is said to be biased or not fair if the object or source of data is tampered with consciously to control the result or probability of different events. For example, if we make a coin in a way that if we flipped that coin we always get head to make the probability to get tail 0, then the coin is a biased coin and a stud,y using that is a biased study. So in given choices,

(A) Errors in data are mistakes made in the unconscious mind. It cannot be the meaning or cause of the biased event.

(B) If participants were only given three choices then they can make different choices using those three so it is partially biased not fully biased.

(C) Not enough people were surveyed cannot be meaning or reason for biased data as the number of experimental data is mentioned in the experiment. So experiment can be done with any size of the sample depending on which the result will be different but not biased.

(D) If participants lead to respond in a specific way then it is a conscious try to control the statistical data. So it is the meaning of the biased statistical study. Hence the correct option is (D).
