Answers

Answer 1

Answer:

You may want to check your question but I've solved various circumstances. Please mark as brainliest :-)

Step-by-step explanation:

[tex]v = 2 - 5t [/tex]

Although, I think you're meant to find time(t) making velocity (v) =0. So,

[tex]0 = 2 - 5t \\ - 2 = - 5t \\ t = - 2 \div - 5[/tex]

If time is 0, then,

[tex]v = 2 - 0 \\ v = 2[/tex]

Answer 2
V=2+(-5)t
V=2-5t
V=-3t

x+ y + z = -3
3y - Z = 4
2x- y - 2z = -5

Answers

Answer:

(-3, 1, -1)

Step-by-step explanation:

x + y + z = -3  --> (1) 3y - z = 4   --> (2)2x - y - 2z = -5 --> (3)

Add up (1) and (2)

x + 3y + y + z - z = -3 + 4 ⇒ x + 4y = 1  --> (4)

Double (2) and subtract from (3)

2x - y - 2z - 2(3y - z) = -5 - 2(4) ⇒ 2x - y - 2z - 6y + 2z = -5 - 82x - 7y = -13 --> (5)

Double (4) and subtract (5)

2(x + 4y) - 2x + 7y = 2 + 13 ⇒ 2x + 8y - 2x + 7y = 15 ⇒ 15y = 15 ⇒ y = 1

Finding x

x + 4(1) = 1 ⇒ x = 1 - 4  ⇒ x = -3

Finding z

-3 + 1 + z = -3 ⇒ z = -1

So the answer is:

(-3, 1, -1)

Step-by-step explanation:

Go up 1 and over 2.

Rise over run

Sorry if it isn't right but I can't see the numbers on the axis's.

It’s 1/2 the reason for this is find two points on the line that is not a decimal. Then do rise over run. Rise is y and run is x when u do that it should be 1/2


Give the slope between the points

Answers

slope is difference in y over difference in x:

m = ( -8 - -3) / (-1 - -5) = (-5)/(4) = -5/4

The Equation of parallel line is y= 3/7 x - 2/7.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

We have equation 3x – 4y = 7 and passes through (-4, -2).

Writing the given equation in slope intercept form as

3x = 7 +4y

4y = 3x- 7

y= 3/7 x - 4/7

so, the slope of parallel line is 3/7.

and, passes through (-4, -2).

y= 3/7 x +b

-2 = 3/7(-4) +b

-2 = -12 /7 + b

b = -2/7

So, the Equation of line is y= 3/7 x - 2/7.

An insect population is growing at a rate of 2t/8 insects per day. Find the size of the insect population after 24 days assuming that there are 100 insects at time t=0.

Answers

Answer:

244

Step-by-step explanation:

Number of insects at time [tex]t[/tex] = 0 are 100.

Rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day

Time, Number of days = 24 days

To find:

Number of insects or size of insect population after 24 days.

Solution:

Given that rate of growth of insects = [tex]\frac{2t}8[/tex] insects per day

We are given that, [tex]t[/tex] = 24 days

Rate of growth =

[tex]\dfrac{2\times 24}{8} = 2\times 3 = 6[/tex]

Growth in Insect population after 24 days = [tex]24\times 6 = 144[/tex]

Initial population = 100

Therefore, the answer is:

The size of insect population after 24 days = 100 + 144 = 244

Write down in terms of n, an expression for the nth term
of the following sequences
a) 25 20 15 10 5​

Answers

Answer:

Solution,

First term (a) = 25

Common difference (d) = Second term - first term = 20 - 25 = -5

Now,

nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n

The nth term of the series is 30 - 5n

Answer:

The nth term will be:

[tex]a_n=-5n+30[/tex]

Step-by-step explanation:

Given the sequence

25, 20, 15, 10, 5​

An Arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

Computing the common difference of all the adjacent terms

[tex]25,\:20,\:15,\:10,\:5[/tex]

[tex]20-25=-5,\:\quad \:15-20=-5,\:\quad \:10-15=-5,\:\quad \:5-10=-5[/tex]

As the difference between all the adjacent terms is the same and equal to

[tex]d=-5[/tex]

Also, the first term is:

[tex]a_1=25[/tex]

Hence, the nth term will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=-5\left(n-1\right)+25[/tex]        ∵ [tex]a_1=25[/tex], [tex]d=-5[/tex]

[tex]a_n=-5n+30[/tex]

Therefore, the nth term will be:

[tex]a_n=-5n+30[/tex]

Step-by-step explanation: 5% of 80=4

;-----------;

Answer:

4 points were scored by bridgette

Step-by-step explanation:

80 times 5 equal 400

Then you move the decimal point to the left by the number of digits the whole number has. In this case, it only has 2, so we move the decimal point 2 spaces over to the left.. Therefore, 400 becomes 4.00. 4.00 is the same as 4, so 4 is your answer.

what fractions of the second ten counting numbers (11,12,13...,.18,19,20) Are composite and prime

will be the brainest

Answers

Answer:

Fraction of composite numbers = 6/10

Fraction of prime numbers = 4/10

Step-by-step explanation:

A composite number can be defined as a positive integer that will be formed when we multiply two smaller positive integers. It can also be said to be a positive integer that has at least one divisor of which 1 and itself are not included.

Thus, it means that the set of numbers given to us which is;

(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), the composite numbers are;

12, 14, 15, 16, 18, 20

This is because each of them have at least one divisor that is neither itself or 1.

Thus, we have 6 out of the 10 numbers as composite.

Fraction of composite numbers = 6/10

Now, a prime number is a number that are only divisible by itself and 1.

Thus,from the given set, the prime numbers are; 11, 13, 17 & 19

We have 4 out of 10 numbers as prime numbers.

Thus, fraction of prime numbers = 4/10

simplifying
