Answers

Answer 1

So, the triangle is equilateral, all its sides are equal⇒

AB=BC=AC=8

In an equilateral triangle, the height is also the median, so it divides the sides into 2 equal parts⇒

AO=OC=8:2=4

by the Pythagorean theorem

[tex]8^2=4^2+BO^2\\BO^2=64-16\\BO=\sqrt{48} \\BO=4\sqrt{3}[/tex]

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

We are given that Lin plays a game that involves a standard number cube and a deck of ten cards numbered 1 through 10.

Therefore,

P(E) = Number of favorable outcomes / total number of outcomes

Outcomes of cube = { 1, 2, 3, 4, 5, 6}

Outcome of Card = {1, 2, 3} from each group.

when both the cube and card have the same number, then Lin gets another turn.

Answer:

A. x=1, y=3

Step-by-step explanation:

you have to isolate y in the bottom equation in order to put it into the top equation. heres what i did:

we will start with the bottom equation, x+y=4. then, subtract x on both sides of the equation. this will isolate y. now, we have the equation; y=4-x.

next, we are going to substitute our new bottom equation in where y is on the top. it looks like this: 2x+(4-x)=5. then, we are going to get rid of the parenthesis, so our equation is: 2x+4-x=5. to solve this, we have to combine like terms, so we will combine the x terms: x+4=5. now, isolate the variable. to do this, we have to take away 4 from each side so we can get x alone: x=1.

so now that we have a value for x, we can use that to find y. we can actually substitute our x-value into the bottom equation to make it easier: 1+y=4. next, we have to isolate the variable, which is y. this gives us the final answer: y=3.

R is inversely proportional to A.
R = 12 when A = 1.5
a) Work out the value of Rwhen A= 5.
b) Work out the value of A when R = 9

Answers

Here are the answer: a) R = 3.6 and b) A = 2

Step-by-step explanation:

Given,

R is inversely proportional to A.

R ∝ [tex]\frac{1}{A}[/tex]

so, R = [tex]\frac{k}{A}[/tex]  -------eq 1 where k is any constant

To find the values of a) R when A = 5 and

b) Value of A when R = 9

Now,

Putting R = 12 and A = 1.5 in eq 1 we get,

12 = [tex]\frac{k}{1.5}[/tex]

or, k = 12×1.5 = 18

From eq 1 we get,

R = [tex]\frac{18}{A}[/tex] --------- eq 2

Now,

a) Putting A= 5 in eq 2 we get,

R = [tex]\frac{18}{5}[/tex] = 3.6

b)  Putting R = 9 in eq 2 we get

R = [tex]\frac{18}{A}[/tex]

or, A = [tex]\frac{18}{9}[/tex] = 2

Answer:

a.3.6

b. 2

Step-by-step explanation:

R is inversely proportional to A

Which means R=k/A

Cross multiply

k=RA

Since R=12

A=1.5

So k=12×1.5

=18

a. We are to determine the value for R

So R=k/A

=18/5

=3.6

b.we are to determine the value for A

So R=k/A

A=k/R

=18/9

These box plots show daily low temperatures for a sample of days in two
different towns. Which statement is the most appropriate comparison of the spreads?

Answers

Given:

The box plots show daily low temperatures for a sample of days in two different towns.

We need to determine the most appropriate comparison of the spreads.

Interquartile range of town A:

The interquartile range can be determined by subtracting the end values of the boxes.

Thus, we have;

Interquartile range = 40 - 20

Interquartile range = 20

Thus, the interquartile range for town A is 20.

Interquartile range for town B:

The interquartile range for town B is given by

Interquartile range = 45 - 35

Interquartile range = 10

Thus, the interquartile range for town B is 10.

Hence, the interquartile range (IQR) for town A, 20° is greater than the IQR for town B, 10°

Hence, Option A is the correct answer.

Which polynomial has zeros of 2, 5, and -4?

B. (2x - 4)(x + 5)(x + 4)
c. 6 - 2)(x - 5)(x - 4)
D. (2x - 4)(x - 5)(x + 4)

Answers

The polynomial has zeros of 2, 5, and -4 is option (d) (2x - 4)(x - 5)(x + 4).

What is polynomial?

A polynomial is a mathematical equation made up of indeterminates and coefficients and uses only addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

How to find the correct polynomial?

To find a polynomial that has zeros 2, 5, and -4 substituted x = 2, 5, and -4 in a polynomial.

By substituted x = 2, 5, and -4 in a polynomial (2x - 4)(x - 5)(x + 4).

(a) For x=2.

The polynomial is

(2(2) - 4)(2- 5)(2 + 4) = (4- 4)(-3)(6)

                                 = 0×-3×6

                                 = 0

(b) For x=5.

The polynomial is

(2(5) - 4)(5 - 5)(5 + 4) = (10-4)(0)(9)

                                  = 6×0×9

                                  = 0

(c) For x=-4.

The polynomial is

(2(-4) - 4)(-4 - 5)(-4 + 4) = (-8-4)(-9)(0)

                                  = -`12×-9×0

                                  = 0

Since (2x - 4)(x + 5)(x + 4) has zeros of 2, 5, and -4

For incorrect options

By substituted x = 2, 5, and -4 in a polynomial  (x + 2)(x + 5)(x - 4), (2x - 4)(x + 5)(x + 4) and (6x - 2)(x - 5)(x - 4) is not equal to zero therefore (a), (b) and (c)is not correct option.

Final answer:

The correct polynomial with zeros of 2, 5, and -4 is represented by Option C, which is (x - 2)(x - 5)(x + 4), even though there is a typo in the option provided.

Explanation:

The zeros of a polynomial are the values for which the polynomial evaluates to zero. These are also the solutions to the equation obtained by setting the polynomial equal to zero. Given the zeros of 2, 5, and -4, we can form a polynomial by finding the factors associated with each zero and then multiplying those factors together.

The factor associated with the zero 2 is (x - 2), the factor for the zero 5 is (x - 5), and the factor for the zero -4 is (x + 4). Multiplying these factors will give us the polynomial that has these zeros:

P(x) = (x - 2)(x - 5)(x + 4).

Comparing this expression with the options provided:

Option A is incorrect because it has factors of (x + 2) and (x - 4), implying zeros of -2 and 4.Option B is incorrect because it has the factor of (2x - 4), which simplifies to (x - 2), but includes the incorrect (x + 4).Option C is correctly formed with (x - 2)(x - 5)(x + 4), despite the typo, and represents the polynomial with the given zeros.Option D is incorrect, similar to option B.

Therefore, the correct answer is Option C, which is (x - 2)(x - 5)(x + 4).

Step-by-step explanation:

Answer:

Volume of a triangular irregular prism=1300.16m^3 = 1300m^2

Volume of a rectangular prism two answers =  1197m^3 or  1233m^3

Step-by-step explanation:

With rectangular prism two answers we need the rectangle surface area first

A = 9 m x 19 m = 171m

or A = 7 m x 19m

The rectangle prism could be 1197m^3  or 1233m^3

depending how big the rectangle is as we calculate that first then multiply by depth. If we had the direction of measurement of the base we would just get one answer and not two.

Rectangular prism A = 171sq  

V = 1197m^3    =  (171sq x 7)

or V=  1233m^3  = 137sq x 9

If the prism is a irregular prism we add the surface area's

V = (a+b+c)B/3

V = (7x19)(9x7) (9x19) x B = 133 + 63 + 197 x 197  =  3900.5/3 =1300.16

Answers

Answer:

- 1, 2, 5, 8, 11

Step-by-step explanation:

Substitute n = 1, 2, 3, 4, 5 into the n th term formula

a₁ = 3(1) - 4 = 3 - 4 = - 1

a₂ = 3(2) - 4 = 6 - 4 = 2

a₃ = 3(3) - 4 = 9 - 4 = 5

a₄ = 3(4) - 4 = 12 - 4 = 8

a₅ = 3(5) - 4 = 15 - 4 = 11

The first 5 terms are - 1, 2, 5, 8, 11

Final answer:

The first 5 terms of the sequence an = 3n - 4 are -1, 2, 5, 8, and 11. Each term is found by substituting the nth term number into the expression and calculating its value.

Explanation:

The student has asked to write the first 5 terms of the sequence an = 3n - 4. To find the terms of this sequence, we simply substitute the values of n (starting from 1 and going up by 1 each time) into the expression and calculate the results.

For n = 1: a1 = 3(1) - 4 = 3 - 4 = -1For n = 2: a2 = 3(2) - 4 = 6 - 4 = 2For n = 3: a3 = 3(3) - 4 = 9 - 4 = 5For n = 4: a4 = 3(4) - 4 = 12 - 4 = 8For n = 5: a5 = 3(5) - 4 = 15 - 4 = 11

Therefore, the first 5 terms of the sequence are -1, 2, 5, 8, 11.
