Answer:

x=0

Step-by-step explanation:

it tells you that

∠LKJ=169

∠SKJ=x+95

∠LKS=74+2x

and by the figure we know that

∠LKJ=∠LKS+∠SKJ

so we have

$169=x+95+74+2x\\\\169=3x+169\\\\169-169=3x\\\\0=3x\\\\x=0$

LKS + SKJ = LKJ

Substitute the numbers into the equation above.

74 + 2x + x + 95 = 169

Combine like terms

3x + 169 = 169

Subtract 169 from both sides

3x = 0

Divide both sides by 3

x = 0

SKJ = x + 95 = 0 + 95 = 95

LKS = 74 + 2x = 74 + 2(0) = 74 + 0 = 74

LKJ = 169

LKS + SKJ = LKJ

74 + 95 = 169. This proves that x = 0

A culture started with 1,500 bacteria. After 5 hours it grew to 2,300 bacteria. How many bacteria with be present after 12 hours

Fynjy0 [20]

Answer:

4185

Step-by-step explanation:

A culture of bacteria grows exponentially according to the following general exponential growth function;

$P_{t}=P_{0}e^{kt}$

where;

p(t) is the population at any given time t.

p(0) is the initial population

k is the growth constant

From the information given we have;

p(0) = 1500

at t = 5, p(t) = 2300; p(5) = 2300

We shall use this information to determine the value of k;

$2300=1500e^{5k}$

Divide both sides by 1500;

$\frac{23}{15}=e^{5k}\\\\ln(\frac{23}{15})=5k\\\\k=0.08549$

Therefore, the population of the bacteria at any time t is given by;

$P_{t}=1500e^{0.08549t}\\\\P(12)=1500e^{0.08549(12)}=4184.3$

A hiker walks up and down a hill. The hill’s cross section can be modeled by the function y = – 3/4|x – 300| + 400 where x and y

Mkey [24]

Find the vertex by either graphing ( See attached picture) or setting the value in the absolute value bracket to 0:

Vertex is (300,400)

Because it is symmetrical, find the length of one side and double ot for total distance.

Using the distance formula shown on the attached picture.
