Answer:

y = 10852 bacteria

Step-by-step explanation:

The equation is exponential growth

y = a  b^x  where a is the initial amount , b is the growth rate and x is the time

At time 0, we have 5000 bacteria

5000 = a * b^0

5000 = a *1

a = 1

At 4 hours, we have 6000 bacteria

6000 = 5000 * b^4

Divide each side by 5000

6000/5000 = b^4

6/5 = b^4

Take the 4th root of each side

(6/5)^(1/4) = (b^4)^(1/4)

1.046635139 = b

Our equation is

y = 5000 (1.046635139) ^ x

We want to find the number of bacteria present after 17 hours

y = 5000 (1.046635139)^17

y=10851.51313

To the nearest whole number

y = 10852 bacteria

Answer:

75°

Step-by-step explanation:

There are 180° in a triangle, so using the ratios and the 180° setup an equation. Solve for x.

5x + 9x + 10x = 180

24x = 180

24x/24 = 180/24

x = 7.5

To find the largest angle measure, use 10x since 10 is bigger than 5 and 9.

10x

10(7.5)

75°

Question 3 of 10 A Assume EFG = JKL. If mLJ = 90°, mL K = 26°, and m< L = 64°, what is the measure of < E?
kumpel [21]

The measure of angle E will be 90 degrees as well.

Assume EFG = JKL.

If mLJ = 90°, mL K = 26°, and m< L = 64°,

<h3>What is the congruent triangle?</h3>

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

We have been given an image of two congruent triangles.

Since, EFG = JKL

therefore, the corresponding angles will be congruent.

m < J = 90° = m< E = 90

By congruence measure of angle, J will be equal to the measure of angle E.

Hence, The measure of angle E will be 90 degrees as well.

What property is occurring in the following example? 11.5 + (- 11.5) = 0
kramer

Answer: A property occurring in the example 11.5 + (-11.5) = 0, is additive inverse.

Step-by-step explanation:

A property where sum of any number and its inverse is equal to zero is called additive inverse property.

For example, 11.5 + (-11.5) = 0

Here, 11.5 is the number and its inverse is (-11.5). The sum of both these is equal to zero. Hence, it shows a property of additive inverse.

Thus, we can conclude that property occurring in the example 11.5 + (-11.5) = 0, is additive inverse.
