A. 130

D. 70

Answers

Answer:

I would think that it would be 130 degrees.

Step-by-step explanation:

Sorry if this doesn't help! Hope you have a good day/night

Answer:

A

Step-by-step explanation:

There are only two plausible answers here, B or A. C and D are impossible because the angle is obviously an obtuse angle, an angle that is greater than 90.

If you're using a protractor, this is rather easy, just use the protractor to measure the angle. If you are not, it gets a bit complicated. I chose A without a protractor because B is only 20 degrees above 90, and it looks too wide to be only 20 degrees above a right triangle.

1. Mrs. Galicia is building a chicken farm in 2021 with an initial population of 3750 chickens. The farm grows at a rate of 2.15% annually. (a) Use the exponential growth model to write an equation that estimates the population t years after 2021. (b) Estimate the population of the town in 2036.
MUST SHOW ALL WORK

Answers

The exponential function is given by [tex]y = 3750(1.0215)^t[/tex], in 2036 the population is 5160.

What is an exponential function?

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y represent the population of the chicken after t years after 2021.

In 2021 with an initial population of 3750 chickens, hence a = 3750.

The farm grows at a rate of 2.15% annually, hence b = 1 + 0.0215 = 1.0215

The exponential function is given by [tex]y = 3750(1.0215)^t[/tex]

In 2036, t = 2036 - 2021 = 15 years

[tex]y = 3750(1.0215)^{15}=5160[/tex]

Answer:

[tex]\huge\boxed{\bf\:x = -\frac{4}{3}}[/tex]

Step-by-step explanation:

[tex]9x ^ { 2 } +24x+20=4[/tex]

Bring 4 to the left hand side of the equation .

[tex]9x^{2}+24x+20-4=0[/tex]

Subtract 4 from 20.

[tex]9x^{2}+24x+16=0[/tex]

Now, factorise it using the splitting-the-middle-term method .

[tex]9x^{2}+24x+16=0 \\9x^{2}+12x+12x+16 =0\\\left(9x^{2}+12x\right)+\left(12x+16\right)=0 \\3x\left(3x+4\right)+4\left(3x+4\right) =0\\\left(3x+4\right)\left(3x+4\right) = 0\\\left(3x+4\right)^{2} = 0[/tex]

Now since both the factors are the same, take one of them,

[tex]3x + 4 = 0\\3x = - 4\\\boxed{\bf\:x = -\frac{4}{3}}[/tex]

1. a number is as much greater than 21 as it is less than 71. find the number
.
2. find 2 consecutive natural number whose sum is 63.​

Answers

1. A number is as much greater than 21 as it is less than 71. Find the number

Solution -

Let the number be x.

x - 21 (number is as much greater than 21)71 - x (it is less than 71)

As both the value of x - 21 and 71 - x is same hence,

=> x - 21 = 71 - x

=> x + x = 71 + 21

=> 2x = 92

=> x = 92/2

=> x = 46

Hence, the number is 46.

2. Find 2 consecutive natural number whose sum is 63.

Let the two consecutive numbers be x and x + 1.

=> x + (x + 1) = 63 (A.T.Q)

=> x + x + 1 = 63

=> 2x = 63 - 1

=> 2x = 62

=> x =62/2

=> x = 31

Hence, the consecutive natural numbers whose sum is 63 are 31 and 32.

On what interval/s is the graph decreasing?

Answers

Answer:

-1 < x < 1/3

Step-by-step explanation:

When the graph is decreasing, it means the the graph's slope is negative, or the graph is going towards negative infinity.

We see from the graph that it starts to decrease from -1 to 1/3. Therefore, our answer is -1 < x < 1/3.

Everywhere else on the graph is increasing.

Greatest to least 9,354 , 9,012 , 9,1 , 9,157

Answers

Answer:

9,354,9,157,9,012,9,1

Step-by-step explanation:

First I do thousands place so 3 numbers have 9 for thousands place.

Numbers are

9,354

9,157

9,012

it cant be 9,012 because this number don't have a hundreds place.

But in hundred place 9,354 would be better than 9,157 because 9,354 had 300 while 9,157 only has 100.

So greatest=9,354

Second greatest=9,157

And last 9,000 number third greatest=9,012.

Our last numbers don't have hundreds or thousands,they have ones but 9 is greater than 1 because...

Say you had 9 pizzas and your friend had 1 you would have more or a greater amount so.

Least=1

and second least=9

Meaning order=

9,356=greatest

9,157

9,012

9

1=least

Step-by-step explanation:

Spontaneous generation is the idea that life can emerge from nonliving matter. Spontaneous
many in the scientific community up until the mid-nineteenth century. A series of simple experiments tested the validity of
this idea. Evidence used to
support spontaneous generation was the observation that foods over time became covered in maggots or fungal and
bacterial growth, implying that these just appeared." The inference behind spontaneous generation is that there is no
"parent" organism
In 1668, Francesco Redi proposed a different hypothesis to explain the specific example of maggots that appeared on spoiled
food. Explain how Redi disproved the idea of spontaneous generation and helped contribute to the idea that cells come from pre-
existing cells.
A)
B)
Redi reasoned that maggots appeared after meat spoiled, breaking down
the rotten meat
Redi reasoned that flies laid eggs on meat, so meat kept away from adult
flies would remain free of maggots
Redi reasoned that meat had to be exposed to air for maggots to appear.
Meat not exposed to air would remain free from maggots.
Redi reasoned that maggots emerged from condensation. As long as the
meat was kept from water sources, there would be no maggots.

Answers

Answer:

Celss do come from pre existing cell.

Redi reasoned that flies laid eggs on meat, so meat kept away from adult

flies would remain free of maggots it is the example .

What contribution did Francesco Redi make to cell theory?

Redi went on to show that while live maggots or flies will reproduce when placed on decomposing flesh in a sealed jar, dead ones would not. This ruled out the existence of any necessary component in extinct organisms as well as the requirement of fresh air for the creation of life.

In a well controlled experiment, Francesco Redi demonstrated how living things are descended from other living things. The third tenet of the cell theory—that cells originate from other living cells—was developed as a result of this research and that of succeeding researchers.

The prehistoric beliefs were put to the test. Francesco Redi disputed the notion that maggots appeared out of thin air from rotting meat in 1668.
