Answers

Answer 1

Answer:

  8.9

Step-by-step explanation:

We know that 81 = 9², so √80 will be slightly less than 9. We can get a pretty good estimate by averaging 9 with 80/9. That result is 8.94, so about 8.9.

The attached graph shows that point on a number line.

Points P, R, and S, are collinear such that R lies on PS. It is known that the ratio of
PR: RS = 1/3}. Find the location of coordinate R if P is located at (-2,-6) and is
located at (10,30).

Answers

Answer:

1,3

Step-by-step explanation:

Sorry if my English is bad

or if my answer is wrong but from my understanding,

as you can recognize from the photos, we need to understand what a collinear is. Collinear are points that are lying in the same straight line. Thus, we can transform the ratio to fractions which means 1 : 3 into 1/3

Hence, the coordinate R is 1/3 between P and S.

Therefore, to determine coordinate R, we must use the formula that is provided. P is (X1, Y1), S is (X2,Y2), M1 is 1 or the Numerator and M2 is 3 or The denominator.

How many solutions does the following system of equations have?
v=3x +2
2v=5x+8

Answers

Answer:

The answer is C, zero solutions.  

Step-by-step explanation:

y = 5/2x + 2

2y = 5x + 8

Multiply 2 to the first equation.  

2y = 5x + 4

Compare it with the other equation

2y = 5x + 4

2y = 5x + 8

Cancel 2y and 5x on both sides.  

Remaining:

4 = 8

4 ≠ 8.  Therefore, the answer is C, zero solutions.

L varies directly with the square of Z. L is 12 when Z is 2. Find the value of L when Z is 4.

Answers

Answer:

L = 48

Step-by-step explanation:

Given that L varies directly with Z² , then the equation relating them is

L = kZ² ← k is the constant of variation

To find k use the condition L = 12 when Z = 2 , then

12 = k × 2² = 4k ( divide both sides by 4 )

3 = k

L = 3Z² ← equation of variation

When Z = 4 , then

L = 3 × 4² = 3 × 16 = 48

squaring on both sides:

sec^2 (thita) = 5 - equation 1

1 + tan^2 (thita) = 5

tan^2 (thita) = 4

tan (thita) = 2.

= tan (thita) - squrt(5)sin(thita)

from eqn - 1

sec(thita) = squrt(5)

Atomic number tells you the number of ______________ contained in the nucleus of an atom. Which is always equal to the number of _____________ in an atom.

Answers

Answer:

The atomic number is equal to the number of protons in an atom

The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element. The atomic number gives the “identity “of an element as well as its location on the Periodic Table.

Step-by-step explanation:

The atomic number is the number of protons in an atom of an element. For example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus.

The atomic number tells you the number of protons contained in the nucleus of an atom. Which is always equal to the number of electrons in an atom.

What is an atom?

An atom is the smallest possible unit of a chemical element.

There are protons and neutrons in the nucleus of an atom, and electrons outside the nucleus.

The atomic number indicates the number of protons or the number of electrons.

Therefore, Atomic number tells you the number of protons contained in the nucleus of an atom. Which is always equal to the number of electrons in an atom.

The fifth term of a geometric sequence is 32 and the eighth term is 4.
(a) Find the ratio. (2 marks)
(b) Find the first term. (2 marks)
(C) Find the sum of the first 50 terms of the sequence. (3 marks)
What is the first term?

Answers

Answer:

a. 1/2

b. 512

c. 1024

Step-by-step explanation:

The nth term of a geometric progression can be written as;

Tn = ar^n-1

where a is the first term, r is the common ratio and n is the term number

From the question;

Fifth term = ar^4 = 32

Eight term = ar^7 = 4

a. We want to find the common ratio

What to do here is that we can divide the 8th by the 5th term

ar^7/ar^4 = 4/32

r^3 = 1/8

r^3 = (1/2)^3

Thus r = 1/2

b. First term

we can make a substitution in any of the two given terms

Let’s use the fifth term

ar^4 = 32

a * (1/2)^4 = 32

a * 1/16 = 32

a = 16 * 32

a = 512

C. Sum of the first 50 terms

To calculate this, we use the sum of terms formula

Sn = a(1- r^n)/1-r

a = 512 , n = 50 and r = 1/2

Making the substitution;

Sn = 512(1-(1/2)^50)/1-1/2

Kindly note that (1/2)^50 will be infinitesimally small and will be close to zero

So we can approximate (1/2)^50 to be zero

Hence;

Sn = 512(1-0)/0.5

Sn = 512/0.5

Sn = 1024

7) Line Segment PR is 5 ft. Find the length of Line Segment PQ and QR. (Hint: use the segment addition postulate.)

Answers

Answer:

PQ = 1 ft

QR = 4 ft

Step-by-step explanation:

From the picture attached,

Segment PR has been divided into two parts by a point Q.

Length of segment PR = 5 feet

Length of segment PQ = (15x - 2) ft

Length of segment QR = (5x + 3) ft

Since, PR = PQ + QR

5 = (15x - 2) + (5x + 3)

5 = 20x + 1

20x = 4

x = [tex]\frac{4}{20}[/tex]

x = 0.2

PQ = 15x - 2

     = 15(0.2) - 2

     = 3 - 2

     = 1 ft

QR = 5x + 3

     = 5(0.2) + 3

     = 1 + 3

     = 4 ft
