Answer:

  (a) On a coordinate plane, a curve starts in quadrant 4 and curves up into quadrant 1

Step-by-step explanation:

A log function does not have a graph that is a line, parabola, or hyperbola. Its graph has a vertical asymptote at x=0, and a x-intercept at x=1. It has positive slope everywhere.

Find the five-number summary for the given data. Min Q1 Q2 Q3 Max
Aleonysh [2.5K]

Answer with Step-by-step explanation:

16 19 21 26 27 29 34 35 35 39 40 41 42 50 50 52 57 60 75 76 78 81 84

the data is already arranged in ascending order

Min=16

Max=84

The quartiles for the odd set of data is given by

Qi=\dfrac{i(n+1)}{4}\ th\ term

where n is the number of elements

Here, n=23

Q1=\dfrac{(23+1)}{4}\ th\ term

Q1=6 th term

Q1=29

Q2=12 th term

Q2=41

Q3=18 th term

Q3=60

Hence, five-number summary for the given data is:

Min  Q1   Q2   Q3   Max

16     29   41     60    84

Could someone do all the problems and/or check my work?
MArishka [77]
11. You’ve done it correctly

12. Let x^2=y
y^2+13y+40=0
(y+8)(y+5)=0
y=8, 5
Since y=x^2
x^2=8 x^2=5
x=+/-√5 x= +/-2√2

13. x^4-x^2-x^2-8=0
x^4-2x^2-8=0
let x^2=y
Y^2-2y-8=0
(y-4)(y+2)=0
y=4, -2
Since y=x^2
X^2=4 X^2=-2
X= +/- 2 This wouldn’t be a real solution

14. It’s pretty much the same process, just substitute y in for x^2. If you’re confused feel free to ask and I can do it, or you can put it through Photomath

15. You’re on the right track so I’m just going to continue from where you left off
x^2(4x+5)-4(x+5)=0
(x^2-4)(4x+5)=0
x= +/- 2 4x=5
x=5/4 or 1 1/4

Hope this helped :)

My age if I am half as old as two more than twice Mack's age if Mack is m years old.
pentagon [3]

Answer:

You are m + 1 years old.

Step-by-step explanation:

Let's say that you are x years old, and Mack is m years old.

x = 1/2( two plus twice m)

x = 1/2(2 + 2m)

x = 1 + m

x = m + 1

Hope this helps!

Ratio of  the number of minutes to the  number of miles = \frac{24}{3}

Number of miles = 10

Number of minutes = ?

Let x be the number of minutes

According to the question,

\frac{24}{3} = \frac{x}{10} \\\\x = \frac{240}{3} \\\\x = 80

Therefore, the number of minutes that Josie will take is 80 minutes.
