Answer:

150

Step-by-step explanation:

Final answer:

Miss Balcon would work 150 hours in 4 weeks as a secretary at a Christian school.

Explanation:

In order to find out how many hours Miss Balcon would work in 4 weeks, we need to first calculate the number of hours she works in a week. She works 7 1/2 hours each day, and since there are 5 days in a week, she works a total of 7 1/2 x 5 = 37 1/2 hours in a week.

Now, to find out how many hours she would work in 4 weeks, we can multiply the number of hours she works in a week by 4. So, 37 1/2 x 4 = 150 hours.

Therefore, Miss Balcon would work 150 hours in 4 weeks.

- 8 × - 4 = 32

32 × - 4 = - 128

Continue this process to obtain the next 2 terms

Answer:

It's d. 0.

Step-by-step explanation:

The log (to any base) of 1 = 0, so log8 1 = 0, and the whole expression is equal to 0:

 0 * log3 27 = 0.

The expression log8 1 * log3 27 evaluates to 0, so the equivalent expression from the options is d - 0.

The expressions we need to evaluate are log8 1 * log3 27. The log of 1, no matter what the base, is always 0. This is because any number raised to the power of 0 is 1. So, log8 1 is equal to 0. Now, evaluate log3 27. The log base 3 of 27 is 3 because 3 cubed (or 3 to the power of 3) is 27. So, log3 27 equals 3. Thus, log8 1 * log3 27 = 0 * 3 = 0. Comparing with the given options, we find that the only equivalent expression is option d - 0.

Answer: If you take 6 in and multiply by 12 You would get 72 inches

*Step By Step explanation* 6 Multiplied by 12 equals 72

Rounding would not be necessary.

Answer:

The correct option is B. 226 inches³

Step-by-step explanation:

The diameter of the cone is given to be 12 inches

So, The radius of the cone will be 6 inches

Also, The height of the cone is given to be 6 inches'

Now, we need to find the volume of the cone.

So, Volume of the cone is given by the formula :

[tex]Volume=\frac{1}{3}\pi\times radius^2\times height[/tex]

[tex]Volume=\frac{1}{3}\times 3.14\times 36\times 6[/tex]

[tex]Volume=226.08[/tex]

[tex]Volume\approx 226.08\:inches^3[/tex]

Therefore, the correct option is B. 226 inches³

Answer:

[tex]z=13(\cos 157\degree +i\sin157\degree)[/tex]

Step-by-step explanation:

The given complex number is

[tex]z=-12+5i[/tex]

The polar form of this complex number is;

[tex]z=r(\cos \theta +i\sin \theta)[/tex], where

[tex]r=\sqrt{(-12)^2+5^2}[/tex]

[tex]r=\sqrt{144+25}=\sqrt{169}=13[/tex]

and

[tex]\theta =\tan^{-1}(\frac{5}{-12})[/tex]

This implies that;

[tex]\theta=157\degree[/tex] to the nearest degree.

Hence the polar form is

[tex]z=13(\cos 157\degree +i\sin157\degree)[/tex]

Answer:

A. 10 fluid ounces

Step-by-step explanation:

One fluid ounce is equal to one quart. This means she had 64 fluid ounces in her jug. She poured 6 3/4 fluid ounces in 8 mugs, so you would multiply 6 3/4 by 8 to get 54. Now you go back to the original amount, 64, and subtract 54 from that. 64 minus 54 equals 10. I hope this helped!

Answer:

Final answer is [tex]a_0=-9[/tex]

Step-by-step explanation:

Given equation is [tex]5-a_0=14[/tex]

Now we need to solve the given equation 5-a_0=14 for the unknown variable  [tex]a_0[/tex] .

We can do that by isolating [tex]a_0[/tex]

To isolate a_0, let's subtract 5 from both sides

[tex]5-a_0-5=14-5[/tex]

[tex]-a_0=9[/tex]

multiply both sides by -1

[tex]-a_0(-1)=9(-1)[/tex]

[tex]a_0=-9[/tex]

Hence final answer is  [tex]a_0=-9[/tex]

Answer:

the explicit formula for the geometric sequence  2,6,18,54 is [tex]a_{n}=a_{1}.r^{n-1}[/tex]

2,6,18,54

Step-by-step explanation:

In the sequence given: 2,6,18,54

The common ration is 3 because

a₁ = 2

a₂= 2*3 =6

a₃ = (2*3)*3 = 2*3^2 = 18

a₄= (2*3*3)*3 =2*3^3 = 54

Here we see for a₂ 3 has power 1, for a₃ 3 has power 2 and so on.

So, the formula will be

[tex]a_{n}=a_{1}.r^{n-1}[/tex]

Here aₙ is the no of term.

a₁ is the first term of the sequence

and r is the common ratio among the sequence.

the answer is A.) 3/10

Option: B is the correct answer.

            [tex]B.\ \ \dfrac{7}{10}[/tex]

We know that P(A or B) i.e. P(A∪B) is calculated by using the formula:

[tex]P(A\bigcup B)=P(A)+P(B)-P(A\bigcap B)[/tex]

( The students are: Fran, Juan , Ian and Ella )

( The students are: Mickey, Mai, Marcus , Ian and Ella)

( since those students are: Ian and Ella)

Hence, we have:

[tex]P(A)=\dfrac{4}{10}\\\\\\P(B)=\dfrac{5}{10}\\\\\\P(A\bigcap B)=\dfrac{2}{10}[/tex]

Hence, we have:

[tex]P(A\bigcup B)=\dfrac{4}{10}+\dfrac{5}{10}-\dfrac{2}{10}\\\\\\i.e.\\\\\\P(A\bigcup B)=\dfrac{4+5-2}{10}\\\\\\i.e.\\\\\\P(A\bigcup B)=\dfrac{7}{10}[/tex]

Answer:

[tex]|A'B'|=\sqrt{5}[/tex]

Step-by-step explanation:

The points A and B have coordinates at (0,4) and (4,2) respectively.

The distance formula can be used to find the length of AB.

[tex]|AB|=\sqrt{(4-0)^2+(2-4)^2}[/tex]

[tex]|AB|=\sqrt{(4)^2+(-2)^2}[/tex]

[tex]|AB|=\sqrt{16+4}[/tex]

[tex]|AB|=\sqrt{20}[/tex]

[tex]|AB|=2\sqrt{5}[/tex]

Since quadrilateral ABCD was enlarged with  a scale factor of [tex]\frac{1}{2}[/tex].

The length of A'B' is

[tex]\frac{1}{2}|AB|[/tex]

[tex]=\frac{1}{2}\times2\sqrt{5}[/tex]

[tex]\therefore |A'B'|=\sqrt{5}[/tex]

The quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2. So, after the dilation the length of A'B' is [tex]\sqrt{5}[/tex] and this can be determined by using the formula of length between two points.

Given :

Given that the quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2. So the points of the quadrilateral ABCD becomes:

[tex]\rm A(0,4) \to A'(0\times \dfrac{1}{2},4\times \dfrac{1}{2}) = A'(0,2)[/tex]

[tex]\rm B(4,2) \to B'(4\times \dfrac{1}{2},2\times \dfrac{1}{2}) = B'(2,1)[/tex]

[tex]\rm C(4,-4) \to C'(4\times \dfrac{1}{2},-4\times \dfrac{1}{2}) = C'(2,-2)[/tex]

[tex]\rm D(-2,-2) \to D'(-2\times \dfrac{1}{2},-2\times \dfrac{1}{2}) = D'(-1,-1)[/tex]

Now, the length of A'B' is given by:

[tex]\rm AB=\sqrt{(4-0)^2+(2-4)^2}[/tex]

[tex]\rm AB=\sqrt{4^2+(-2)^2}[/tex]

[tex]\rm AB=\sqrt{20}[/tex]

[tex]\rm AB = 2\sqrt{5}[/tex]

[tex]\rm A'B' = \dfrac{1}{2}AB[/tex]

[tex]\rm A'B' = \sqrt{5}[/tex]

Therefore, the correct option is a).

Answer:

In mathematics, a parabola is a plane curve that is mirror-symmetrical and is approximately U-shaped.

Answer:

Step-by-step explanation:

a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity ideally follows a curve of this shape.

A parabola is a two-dimensional, mirror-symmetrical curve, which is approximately U-shaped when oriented as shown in the diagram below, but which can be in any orientation in its plane. It fits any of several superficially different mathematical descriptions which can all be proved to define curves of exactly the same shape.

Answer:

4.4721

Step-by-step explanation:

Answer:

The correct answer option is y = -4.

Step-by-step explanation:

We are to find the equation of the mid-line for the following function:

[tex]y=3cos(x-\pi)-4[/tex]

[tex]3 cos((x - \pi ) - 4 = 3 cos(x) - 4[/tex] because [tex]cos(x-\pi) = cos(x)[/tex]

[tex]-1 \leq cos(x) \leq 1[/tex]

[tex]-3 \leq 3cos(x) \leq 3[/tex]

[tex]-3-4 \leq 3 cos(x)-4 \leq 3-4[/tex]

[tex]-7 \leq 3 cos(x)\leq-1[/tex]

The range is -7 to -1 so the midpoint is [tex]\frac{-7-1}{2} =-4[/tex]

Therefore, the equation of the mid-line for the given function is y = -4.

Answer:

118°

Step-by-step explanation:

Since it is an isosceles triangle, two angles must be the same.

Also angles in a triangle add up to 180° and from this we can deduce that

x + ( 31 + 31 ) = 180

( Simplify )

x + 62 = 180

( - 62 from both sides )

x = 118°

Answer:

I recommend the work that pays  $45,000 a year because the monthly income is greater than the other job

Step-by-step explanation:

we know that

The first work pays $45,000 a year

so

The monthly income is equal to

$45,000/12=$3,750 per month

The second work pays $20.50 an hour

Remember that

1 year= 52 weeks

so

In one year pays -----> (8)*(5)*(52)($20.50)=$42,640 a year

The monthly income is equal to

$42,640/12=$3,553.33 per month
