Answer:

The frog will catch the fly after 2 seconds of his jump.

Step-by-step explanation:

It is given that a frog is about to hop from the bank of a creek. The path of the jump can be modeled by the equation h(x) = -x² + 4x + 1, where h(x) is the frog's height above the water and x is the number of seconds since the frog jumped and a fly is cruising at a height of 5 feet above the water.

Now, let us assume that the frog catches the fly that is cruising at a height of 5 feet above the water;

=> h = 5 feet

So, let us put the value of h = 5 for time x;

=> h(x) = -x² + 4x + 1

=> 5 = -x² + 4x + 1

=> x² - 4x - 1 + 5 = 0

=> x² - 4x + 4 = 0

Now, on solving the above equation we get;

=> x² - 4x + 4 = 0

=> x² - (2 + 2)x + 4 = 0

=> x² - 2x - 2x + 4 = 0

=> x (x - 2) - 2 (x - 2) = 0

=> (x - 2) (x - 2) = 0

On comparing and solving for the value of x we get;

=> (x - 2) = 0

=> x = 2

and

=> (x - 2) = 0

=> x = 2

Therefore, the frog will catch the fly after 2 seconds of his jump.

Answer:

-10 and -10

Step-by-step explanation:

Can you use the same number twice?

The only option that is not viable to solve the systems of equations is:

D. Substitute y = 6/5x - 12 into the first equation

Given the systems of equations,

2x + y = 20 ----> equation 1

6x - 5y = 12 ----> equation 2

In order to solve the system of equations using the substitution method, rewrite 2x + y = 20:

2x + y - 2x = 20 - 2x

y = 20 - 2x

Or

2x = 20 - y

x = 10 - 1/2y

Or

6x - 5y = 12

-5y = -6x + 12

y = -6/5x - 12/5

or

6x = 12 + 5y

x = 2 + 5/6y

Therefore, the only option that is not viable to solve the systems of equations is:

Given that  ∠ABC and ∠DEF are supplementary, the numerical value of ∠ABC and ∠DEF are 68° and 112° respectively.

Supplementary angles are angles that sum up to 180 degrees.

Given the data in the question;

Since ∠ABC and ∠DEF are supplementary, it means they sum up to 180 degrees.

Measure of ∠ABC + Measure of ∠DEF = 180°

Plug in the given values and solve for x

(6x + 8) + (12x − 8) = 180

6x + 8 + 12x − 8 = 180

6x + 12x + 8 - 8 = 180

18x + 0 = 180

18x = 180

x = 180/18

x = 10

Now, the numerical measure of each angle will be;

Measure of ∠ABC = (6x + 8)° = 6(10) + 8 = 60 + 8 = 68°

Measure of ∠DEF = (12x − 8)° = 12(10) - 8 = 120 - 8 = 112°

No extraneous solution to the equation:

The equation is:

[tex]x^{1/2}[/tex] - [tex](x- 5)^{1/2}[/tex] = 2

To know whether the equation has an extraneous solution first we need to find the value of x.

[tex]x^{1/2}[/tex] - 2 = [tex](x - 5)^{1/2}[/tex]

[tex]x^{1/2} - 2[/tex] = [tex](x - 5)^{1/2}[/tex]

Now squaring both sides of the equation we have:

[tex](x^{1/2} - 2)^{2}[/tex] = x - 5

x - 4[tex]x^{1/2}[/tex] + 4 = x -5

[tex]x^{1/2}[/tex] = -9/4

x = 81/16

Now we have to put the value of x in the equation.

[tex](81/16)^{1/2}[/tex] - [tex](81/16 - 5)^{1/2}[/tex] =2

9/4 - 1/4 =2

8/4 = 2

k, q, r, t are directly proportional to p and s is inversely proportional to p.

The inversely proportional property state that two values are opposite to each other. If there will increase in one value or quantity then the another quantity will automatically decrease with the same ratio and if one quantity will decrease then another will increase with that ratio.

Say if x and y are inversely proportional, then mathematically

x ∝ 1 / y

The directly proportional property state that two values are same to each other. If there will increase in one value or quantity then the another quantity will automatically increase with the same ratio and if one quantity will decrease then another will also decrease with that ratio.

Adding 3 on both the sides of the equation, we get

[tex](2x+3)^{3/4}[/tex] = 8

On the right hand side of the equation, 8 can also be written as
