Answer:

x is about 10.39, y is about 20.78

Step-by-step explanation:

15)

[tex]\tan 30=\dfrac{x}{18}\\x=18 \cdot \tan 30\approx 10.39\\\cos 30 =\dfrac{18}{y}\\y=\dfrac{18}{\cos 30}\approx 20.78[/tex]

Answer:

x=6√3

y=12√3

Step-by-step explanation:

This is a 30 60 90 triangle.

The side opposite from the angle 60 is x√3, which makes 18=x√3, which eventually solves to x=6√3

The side opposite from the 90 degree angle is 2x, so multiply 6√3 by 2, which is 12√3, making y equal 12√3

Answer: C.

f(t) = P(1.02)4t

Step-by-step explanation:

f(t) = P(1.02)4t will have the greatest compound interest because the interest is on quarterly bases with an increment of 1.02 and the rate of 8%

Note : 8/100 × 1/4 = 0.02

There is no increment in D and A is yearly based. Option C is for 6 month.

Answer:

25) x = 18 26) x = 50

Step-by-step explanation:

25) 108 + 4x = 180

108 + 4x = 180

-108           -108

4x = 72

x = 18

26)

101 + (x + 29) = 180

101 + 29 + x = 180

130 + x = 180

-130        -130

x = 50

Answer:

B. 3

Step-by-step explanation:

If there are inclusion points on the numberline, then 3 is the only viable choice, as the only 2 whole numbers that can work is 2 & 3. If there is no inclusion, then none, as it will have to be a decimal (or fraction) between 2 & 3.

c

Step-by-step explanation:

i took the test and got it right so... and do you have Mr. Hoffman

The sum of the first six terms of the following sequence is ∑(from i=1 to 6) (-10 - 3(i-1)), the correct option is A.

Lets suppose its initial term is f=a , multiplication factor is  r

and let it has total n terms, then, its sum of a geometric sequence is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

We are given that;

The sequence;  −10, −13, −16, …

Now,

The given sequence is an arithmetic sequence with first term (a1) = -10 and common difference (d) = -3.

Using this formula, we can find the first six terms of the sequence as follows:

a1 = -10

a2 = -10 + (-3) = -13

a3 = -10 + 2(-3) = -16

a4 = -10 + 3(-3) = -19

a5 = -10 + 4(-3) = -22

a6 = -10 + 5(-3) = -25

We can represent the sum of the first six terms using sigma notation as:

∑(from i=1 to 6) ai = (-10) + (-13) + (-16) + (-19) + (-22) + (-25) = -105

The sum of the first six terms of the given sequence is -105.

Using sigma notation, we can write this as:

∑(from i=1 to 6) (-10 - 3(i-1)) = -105

Therefore, by the geometric sequence the answer will be ∑(from i=1 to 6) (-10 - 3(i-1)).

Answer: The MAD is 1.6

Step-by-step explanation:To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

Answer: z=2.8

This is how I do!

Step-by-step explanation:

51-2z-8z=23

We simplify the equation to the form, which is simple to understand  

51-2z-8z=23

We move all terms containing z to the left and all other terms to the right.  

-2z-8z=+23-51

We simplify left and right side of the equation.  

-10z=-28

We divide both sides of the equation by -10 to get z.  

z=2.8

Answer:

Z=2.8

Step-by-step explanation:

51-10z=28

(/10) =2.8

The answer is

[tex] - 5 < x < 2[/tex]

Step-by-step explanation:

First you have to seperate them :

[tex] - 2 < x + 3[/tex]

[tex]x + 3 < 5[/tex]

Next you can solve it by moving all the unrelated terms to the other side :

[tex] - 2 < x + 3 \\ - 2 - 3 < x + 3 - 3 \\ - 5 < x \\ x > - 5[/tex]

[tex]x + 3 < 5 \\ x + 3 - 3 < 5 - 3 \\ x < 2[/tex]

Answer:

-5 < x < 2

Step-by-step explanation:

Subtract 3 from each of the three sides.

-2 < x + 3 < 5

-2 - 3 < x + 3 - 3 < 5 - 3

-5 < x < 2

Answer: 36%; yes, the % change is equal to the percent discount

Step-by-step explanation:

Initial price = $69.99

Final price = $44.99

change in price = |(final - initial)|

change in price = |(44.99 - 69.99)|

change in price = $25

25/69.99 = x/100

100(25/69.99) = x

100(0.357) = x

35.7% = x

x = 36%
