Answer:

-(4 x^2 - 5 x + 28)

-4 x^2 + 5 x - 28

-1\/16 (8 x - 5)^2 - 423\/16

Step-by-step explanation:

any of these equations are equal to  3x^2+5x-7(x^2+4)​

The equivalent expression is -4 x² + 5 x - 28.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given:

3x²+5x-7(x²+4)​

Now,

-(4 x² - 5 x + 28)

-4 x² + 5 x - 28

-1\/16 (8 x - 5)² - 423\/16

Hence, the  equivalent expression is -4 x² + 5 x - 28.

Answer:

[tex]\frac{1}{32}[/tex]

Step-by-step explanation:

According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.

Total outcome = 2

pr(male) = [tex]\frac{1}{2}[/tex]

pr(female) = [tex]\frac{1}{2}[/tex]

Therefore the probability of male equals the probability of females i.e [tex]\frac{1}{2}[/tex].

Therefore,

pr(a litter of 5 puppies will be males) = [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]

                                                           = [tex]\frac{1}{32}[/tex]

According to Reese's model, the probability that a litter of 5 puppies will be males is [tex]\frac{1}{32}[/tex].

Answer:  I think it's 50

Step-by-step explanation:

5 = 25

15 = 75

Presumeably, 10 = 50

Answer:

50

Step-by-step explanation:

5th term=a+4d

10th term=a+9d

15th term=a+14d

since

5th term=25 and the 15th term=75

so we find the value of unknown 'd' with is the common difference

a+4d=25

a+14d=75

-10d=-50

d=5

after finding the value of d we can now find the value of 'a'

a+4(5)=25

a=5

hence the 10th term can be obtained

a+9d

5+9(5)=50

Answer:

x = ± i, x = ± [tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

- 2[tex]x^{4}[/tex] + 2x² + 4 = 0 ( divide through by - 2 )

[tex]x^{4}[/tex] - x² - 2 = 0

Use the substitution x² = u , then

u² - u - 2 = 0 ← in standard form

(u - 2)(u + 1) = 0 ← in factored form

Equate each factor to zero and solve for u

u - 2 = 0 ⇒ u = 2

u + 1 = 0 ⇒ u = - 1

Change back into terms of x, that is

x² = 2 ( take the square root of both sides )

x = ± [tex]\sqrt{2}[/tex]

x² = - 1 ( take the square root of both sides )

x = ± [tex]\sqrt{-1}[/tex] = ± i

x = ± [tex]\sqrt{2}[/tex] ← real solutions

x = ± i ← complex solutions

Answer:

15 degrees

Step-by-step explanation:

Answer:

The 2nd option.

Step-by-step explanation:

Since  Angle D is 68 degrees side EF would be the longest.

Side DF is the shortest side it is opposite the smallest angle.

Side EF is in the middle since opposite the next biggest angle.

Side EF is again the longest since Angle D is the biggest at 68 degrees.

Answer:

[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Step-by-step explanation:

Given

P = Test is positive

D = Disease is present

Required

Write an expression when disease is present but test says that the disease is not present

The above statement can be split to two

Disease is Present          &        Test is not positive

The first statement:

Disease is Present  means D

The second statement

Test is not positive means not P

Mathematically;

not P means P' or [tex]P^c[/tex]

So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Answer:

The change in elevation of the seagull is -16 ft

Step-by-step explanation:

Displacement

The displacement, unlike distance, considers the direction of the lengths occurring in the systems.

To solve the problem, we need to set a zero-level reference. Let's assume the sea level as zero height, any position above this reference as positive, and any position below this reference as negative.

The seagull is flying at a height of 10 ft above the ocean. Thus, its position is positive +10 feet.

The seagull then dives into the water to catch a fish at a depth of 6 feet. This position is negative: -6 ft.

The change in elevation is found by subtracting the final elevation and the initial elevation:

change = -6 ft - 10 ft = -16 ft

The change in elevation of the seagull is -16 ft
