Answer:

556

Step-by-step explanation:

There's an initial population of 139 bacteria in a colony. If it doubles every 189 minutes, then the population would be 556 in 378 minutes from now.

189th minute= 139+139=278

Since 189+189= 378, Just double 278 again, which gives you 556.

Answer:

556

Step-by-step explanation:

So, 378/189=2. So it will double two times. x2x2=x4. 139x4=556.

A company plans to build a wheelchair ramp with the following
Liono4ka [1.6K]

9514 1404 393

Answer:

  yes

Step-by-step explanation:

The height that would be allowed with a ramp 43.5 feet long is ...

  h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft

The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.

__

The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.

F(m)=m^4-6m^3+5m^2+10m-4 at m=4
Alexandra [31]

Answer:

F(m) = -12

Step-by-step explanation:

Given the function:

F(m)=m^{4}-6m^{3}+5m^{2}+10m-4

When m = 4, we substitute the variable 'm' for the number 4:

F(m)=4^{4}-6(4)^{3}+5(4)^{2}+10(4)-4

F(m) = 256 - 384 + 80 + 40 - 4

F(m) = -12

From the observation deck of a skyscraper, Madison measures a 67^{\circ} ∘ angle of depression to a ship in the harbor below. If
mrs_skeptik [129]

The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.

<h3>What is trigonometric ratio?</h3>

Trigonometric ratio is used to show the relationship between the sides and angles of right angled triangle.

Let d represent the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:

Angle = 90 - 67 = 23°

Using trig ratio:

tan(23) = d/1143

d = 485.2 feet

The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.

You go to the mall to make some purchases. You buy 3 dresses which cost $59.99 each and a pair of shoes that cost $75. What is t
mina [271]
Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892

Solution: bill would be around $275
