Answer:

x=-½

x=5

Step-by-step explanation:

2x²-5x-10=4x-5

2x²-5x-10-4x+5=0

2x²-9x-5=0

2x²+x-10x-5=0

x(2x+1)-5(2x+1)=0

(2x+1)(x-5)=0

2x+1=0

2x=-1

x=-1/2

x-5=0

x=5

67%, 72%, 77%

Step-by-step explanation:

it says that people recommend the same intensity for three then increasing for three then decreasing thus repeating this cycle

so anyways for the fourth fifthe and sixth visit itll be an increasing sensitivity

Anyways for the fourth fifth and sixth visit, it'll be an increased sensitivity.

We have given that,

The table represents the recommended exercise intensity for an aerobic program based on the number of visits since beginning the program.

A 2-column table with 6 rows titled Intensity of Exercises. The first column is labeled Number of Visits with entries 1, 2, 3, 4, 5, and 6.

66%, 69%, 72%

63%, 65%, 67%

67%, 72%, 77%

The intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the energy's propagation direction.

Answer:

The Trout will have to jump 49 cm in order to catch the insect

Step-by-step explanation:

Here, we want to calculate the distance the Trout has to jump in order to catch the Insect

To calculate this, we need to know the difference in the distances

From what we have, the Trout is 32 cm below the surface while the Insect is 17 cm above the surface of the lake

The difference in height which will represent the distance that the Trout has to jump to catch the insect will be ;

17 + 32 = 49 cm

The composite function f(g(x)) is 2/x + 1

Given the function

We are to get the composite function (fog)(x)

This can be written as:

f(g(x)) = f(2/x)

f(2/x)= 2/x + 1

Hence the composite function f(g(x)) is 2/x + 1

Answer:

8. The length of the longest side is 40 ⇒ H

Step-by-step explanation:

8. In the given figure

∵ The triangle has two equal sides 2x + 12 and 5x - 9

→ Equate their expressions to find the value of x

∴ 5x - 9 = 2x + 12

→ Add 9 to both sides

∵ 5x - 9 + 9 = 2x + 12 + 9

∴ 5x = 2x + 21

→ Subtract 2x from both sides

∵ 5x - 2x = 2x - 2x + 21

∴ 3x = 21

→ Divide both sides by 3 to find x

∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]

∴ x = 7

∵ The longest side is 6x - 2

→ Substitute the value of x in its expression to find its length

∴ The longest side = 6(7) - 2 = 42 - 2

∴ The longest side = 40

∴ The length of the longest side is 40

Answer:B

Step-by-step explanation:

The acceleration of the block is 13 m/sec².

Acceleration is defined as the rate of change of velocity with respect to time, It is a vector quantity with units of m/sec².

Force = 52 N

Mass of the block = 4kg

Acceleration =?

The formula for the force applied to any object is given by

F = mass *  Acceleration

Substituting the values

52 = 4 * Acceleration

Acceleration = 52 / 4 = 13 m/sec².

Therefore, The acceleration of the block is 13 m/sec².

Answer:

40.3miles/hr

Step-by-step explanation:

Given parameters:

Time taken  = 40min

Distance covered  = 27mile

Unknown:

Speed in miles per hour = ?

Solution:

Speed is the distance divided by the time;

   Speed  = [tex]\frac{distance }{time}[/tex]

convert the time to hrs;

               60min  = 1hr

                40min  = [tex]\frac{40}{60}[/tex]   = 0.67hr

Insert the parameters and solve;

        Speed  = [tex]\frac{27}{0.67}[/tex]   = 40.3miles/hr

Answer:

b in terms of A and h will be:

[tex] \boxed{ \rm{b = \frac{2A}{h} }}[/tex]

Step-by-step explanation:

This is basically the formula for finding the area(A) of the triangle in terms of b and h. We have to solve for b in terms of A and h.

[tex] \rm{A = \dfrac{1}{2} bh}[/tex]

Multiplying 2 in the LHS. This is shift because inverse of division is multiplication.

[tex] \rm{2A = bh}[/tex]

Dividing h from both sides,

[tex] \rm{b = \dfrac{2A}{h} }[/tex]

You will "eliminate" the y variable, and only be left with the x variable.

  create widespread damage

Step-by-step explanation:

Hurricanes are tropical storms that generally develop over the Atlantic ocean. The ones of concern in the US are the ones that follow a westward path. They generally gain strength over water, and dissipate over land. They can last several days, though their movement generally means the worst impact in a given area lasts only a matter of hours. (Clean-up may take months or years.)

Hurricanes are one of the largest of storm systems, so can cause widespread damage.
