I really need help on this one​

Answer:

1.040

Step-by-step explanation:

log √(120)

= (1/2) log 120

120 = 2³ • 3 • 5

= 0.5(3 log 2 + log 3 + log 5)

Express log 5 in terms of log 2.

log 5 = log (10/2) = log 10 - log 2 = 1 - log 2

= 0.5(3 log 2 + log 3 + 1 - log 2)

= 0.5(2 log 2 + log 3 + 1)

= 0.5(2*0.3010 + 0.4771 + 1)

= 1.03955 or 1.040

Answer:

1=6

7=42

2.5=15

5=30

Step-by-step explanation:

Multiply each original value by the scale factor

1×6=6

7×6=42

2.5×6=15 (2×6 + 6×0.5)

5×6=30

Answer:

Original: 5 cm = Enlarged: 30 cm

Original: 7 cm = Enlarged: 42 cm

Original: 2.5 cm = Enlarged: 15 cm

Answer:

[tex]\sqrt{210/16}[/tex]  

Step-by-step explanation:

By saying reach the ground, it means the altitude w[tex]\sqrt{}[/tex]ill be zero, so the equation will be: 210 - 16t^2 = 0

210 = 16t^2, t = [tex]\sqrt{210/16}[/tex]  

Answer:

- 6 + 24 i

Step-by-step explanation:

Use distributive property to remove parentheses and then combine like terms:

6 + 9i - 12 + 15 i = - 6 + 24 i

Answer:

Yes because the 1st and 3rd one are functions

Step-by-step explanation:

Answer:

[tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex]

Step-by-step explanation:

Given expression is,

f(x) = 8x³ - 6x² - 36x + 27

For zeros of the function,

f(x) = 0

8x³ - 6x² - 36x + 27 = 0

2x²(4x - 3) - 9(4x - 3) = 0

(2x² - 9)(4x - 3) = 0

(2x² - 9) = 0

x² = [tex]\frac{9}{2}[/tex]

x = [tex]\pm\frac{3}{\sqrt{2}}[/tex]

x = [tex]\pm \frac{3\sqrt{2}}{2}[/tex]

Or (4x - 3) = 0

x = [tex]\frac{3}{4}[/tex]

Therefore, all zeros of the given functions are  [tex]x=-\frac{3\sqrt{2}}{2},\frac{3}{4},\frac{3\sqrt{2} }{2}[/tex].

Answer:

C) 1/6

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

We have 8 + 10 + 4 + 2 = 24 coins

Of those, 4 are nickels. So

[tex]p = \frac{4}{24} = \frac{1}{6}[/tex]

The correct option is given by option C.

Answer:

x > -6

Step-by-step explanation:

Answer:

Each point is 4 units away from the y-axis.

Step-by-step explanation:

Coordinates of point (x, y) defines the distance of the point from y-axis and x-axis.

x-coordinate → distance from the y-axis

y-coordinate → distance from x-axis

Coordinates of A → (-4, 3)

Coordinates of B → (-4, -3)

So both the points have same x-coordinates but opposite y-coordinates.

Therefore, each point is 4 units away from the y-axis.

Answer:

Answer:

23

Step-by-step explanation:

From the graph, derive the best fit equation :

Using the points ;

(0,2.5)  (100 ,35)

x1 = 0 ; y1 = 2.5 ; x2 = 100 ; y2 = 35

Slope formula, m = (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = 0.325

The y intercept, value on the graph where best fit line crosses the y axis = 2.5

The equation :

y = mx + c

c = intercept ; m = slope

y = 0.325x + 2.5

y = Number of cars

x = number of customers

The number of customers if there are 10 cars parked :

10 = 0.325x + 2.5

10 - 2.5 = 0.325x

7.5 = 0.325x

x = 7.5 / 0.325

x = 23.076

x = 23

Answer:

16e-9

Step-by-step explanation:

===============================================================

In order to simplify this expression, we need to combine like terms:-

[tex]\longrightarrow\sf{6e+10e-9}[/tex]

Add the e's:-

[tex]\longrightarrow\sf{16e-9}[/tex]

Are there any more like terms? No, because 16e and -9 aren't like terms.

====================================================

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Step-by-step explanation:

Answer:hourly pay for the junior employee in dollars and cents=$10.25

Step-by-step explanation:

Step 1

Total amount  senior employee is being paid = amount per hour x hours worked

 = $14 × 16 = $224.00

 Total amount of junior employee  since he/ she collects $39.50 less than senior employee= $224.00 - $39.50

                             = $184.50

Step 2

hourly pay of junior colleague= Total pay of junior colleague/ Hours worked

 =$184.50 / 18 hours

 = $10.25 per hour

Answer: 24 grams of element would remain.

Step-by-step explanation:

Exponential function for decay:

[tex]f(x)=Ab^{\frac{x}{n}}[/tex] ....(i) , where A = initial value , b = decay factor, x = time , n= time per period

As per given,

A = 569 grams , [tex]b=\dfrac12[/tex]

n= 5 years, t = 23 years

Put all values in (i) , we get

[tex]f(23)=590(\dfrac12)^{\frac{23}{5}}\\\\\\=590\times 0.0412346222117\\\\=24.3284271049\approx 24[/tex]

Hence, after 23 years , 24 grams of element would remain.

Answer:

2 / 13

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of 4's = 4 ( 1 for each suit)

Number of 6's = 4 (1 for each suit)

Probability, P = required outcome / Total possible outcomes

P(a 4) = 4 / 52 = 1/ 13

P(a 6) = 4 /52 = 1/13

Probability of either a 4 or a 6

P(a 4) + P(a 6)

1/13 + 1/13

= 2 / 13
