Answer:
x > 0
Step-by-step explanation:
Given :-
√[3x²] ÷ √[4x ]And we need to find the value of x for which the expression is defined . The expression is ,
[tex]:\implies[/tex] √[3x²] ÷ √[4x]
As we can see that x is inside the squareroot. So for defining the expression the value of x should be Greater than 0 . As negative inside the squareroot will give rise to imaginary numbers.
Solution :-
[tex]:\implies[/tex] x > 0
In interval notation :-
[tex]:\implies\bf x \in ( 0 , \infty) [/tex]
Therefore x should be Greater than 0 .

If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by y = 56t − 1.86t2.
(a) Find the average speed over the given time intervals.
(i) [1, 2] m/s
(ii) [1, 1.5] m/s
(iii) [1, 1.1] m/s
(iv) [1, 1.01] m/s
(v) [1, 1.001] m/s
(b) Estimate the speed when t = 1. m/s.
Answers
Answer: (a) (i)50.42 m/s (ii) 51.35 m/s (iii) 52.094 m/s (iv) 52.2614 m/s (v) 52.27814 m/s
(b) 54.14 m/s
Step-by-step explanation:
The average speed over the given time interval [a,b]: = [tex]\frac{y(b)-y(a)}{b-a}[/tex]
Given: If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by [tex]y = 56t − 1.86t^2.[/tex]
(a)
(i) average speed = [tex]\frac{y(2)-y(1)}{2-1}[/tex]
[tex]=\frac{56(2)-1.86(2)^2-(56(1)-1.86(1)^2)}{1}[/tex]
[tex]=50.42[/tex] m/s
(ii) average speed = [tex]\frac{y(1.5)-y(1)}{1.5-1}[/tex]
[tex]=\frac{56(1.5)-1.86(1.5)^2-(56(1)-1.86(1)^2)}{0.5}[/tex]
[tex]=51.35[/tex]m/s
(iii) average speed = [tex]\frac{y(1.1)-y(1)}{1.1-1}[/tex]
[tex]=\frac{56(1.1)-1.86(1.1)^2-(56(1)-1.86(1)^2)}{0.1}[/tex]
[tex]=52.094[/tex]m/s
(iv) average speed = [tex]\frac{y(1.01)-y(1)}{1.01-01}[/tex]
[tex]=\frac{56(1.01)-1.86(1.01)^2-(56(1)-1.86(1)^2)}{0.01}[/tex]
[tex]=52.2614 [/tex]m/s
(v) average speed = [tex]\frac{y(1.001)-y(1)}{1.001-01}[/tex]
[tex]=\frac{56(1.001)-1.86(1.001)^2-(56(1)-1.86(1)^2)}{0.001}[/tex]
[tex]=52.27814 [/tex]m/s
(b) [tex]y(1)=56(1)-1.86(1)^2[/tex]
[tex]=56-1.86[/tex]
[tex]= 54.14[/tex] m/s

A company makes bicycles in two sizes. The smaller bicycle weighs 18.5 pounds. The larger bicycle weighs 1 1/4 times as much as the smaller bicycle. How many pounds does the larger bicycle weigh?
Answers
Answer:
[tex] \displaystyle23.125 \: \text{pounds}[/tex]
Step-by-step explanation:
we are given that,
the weight of a smaller bicycle is 18.5 poundsthe weight of a larger bicycle is 1¼ times as much as the smaller bicyclein order to figure out the weight of the larger bicycle we can consider using equation
let the weight of the larger bicycle be L
according to the second condition
we acquire
[tex] \displaystyle L = 18.5 \times 1\frac{1}{4} [/tex]
to simplify the mixed fraction to improper fraction we can use the formula given by
[tex] \displaystyle \rm c\frac{a}{b} \xrightarrow{ \text{improper fraction}} \frac{b \times c + a}{b} [/tex]
by using the formula we get
[tex] \displaystyle L = 18.5 \times \frac{5}{4} [/tex]
simplify multiplication:
[tex] \displaystyle L =\frac{92.5}{4} [/tex]
simplify division:
[tex] \displaystyle L =23.125[/tex]
hence,
the larger bicycle weighs 23.125 pounds
