Choice 3: [tex]\sqrt{2}[/tex]
Step-by-step explanation:
The first thing is that you have to break the √10. The only way you can break it is to make it into a 5 and a √2. So now it should look like this [tex]\frac{5}{5\sqrt{2}}[/tex]. Then we will divide the 5 by 5 and that'll become 1, so we are left with a [tex]\sqrt{2}[/tex] and that's it.

Answer:
The answer is below
Step-by-step explanation:
A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, and her running speed, in miles per hour, when she runs at a constant speed of 5.4miles per hour for m minutes, and then at b miles per hour for n minutes
Solution:
Given that the student runs for a total of 30 minutes per day. He runs at 5.4 miles per hour for m minutes, and then at b miles per hour for n minutes.
Hence:
m + n = 30
60 minute = 1 hour. Therefore, m minute = m/60 hour, n minute = n/60 hour.
The distance traveled is the product the speed in miles per hour and the time taken to cover the distance. Distance = speed * time
The total distance ran (D) is:
D = 5.4(m/60) + b(n/60)

Amadahy wants to buy a card and two gifts for her friend. Cards cost 3.49 each and gifts cost $10.63 each. Amadahy has a 20$ bill. Does she have enough to buy these items? If so, how much change will she receive? Will she receive? If not, how much more money does she need
Answers
Answer:
Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).
Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).

Given:
The zeros of the polynomial are [tex]-2,\pm 5,4[/tex].
Degree = 4
Leading coefficient = 1
To find:
The polynomial.
Solution:
If c is a zero of a polynomial, then (x-c) must be a factor of the polynomial.
Here, -2,4,-5, 5, are zeros of the required polynomial, so (x+2), (x-4), (x+5), (x-5) are factors of required polynomial.
[tex]p(x)=(x+2)(x-4)(x+5)(x-5)[/tex]
[tex]p(x)=(x^2-4x+2x-8)(x^2-5^2)[/tex] [tex][\because a^2-b^2=(a-b)(a+b)][/tex]
[tex]p(x)=(x^2-2x-8)(x^2-25)[/tex]
Using distributive property, we get
[tex]p(x)=x^2(x^2-25)-2x(x^2-25)-8(x^2-25)[/tex]
[tex]p(x)=x^4-25x^2-2x^3+50x-8x^2+200[/tex]
On combining like terms, we get
[tex]p(x)=x^4-2x^3+(-25x^2-8x^2)+50x+200[/tex]
[tex]p(x)=x^4-2x^3-33x^2+50x+200[/tex]
Here, the leading coefficient is 1. So, it is the required polynomial.
Therefore, the correct option is E.

A
$516.00
B
$354.00

Answers
20% of 340 you multiply the first digit of the percentage with the 2 numbers of 340
So 2 x 43= 86 that’s the discount
430-86=344 that’s the final price

What is a Trigonometric Ratios?Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.
The step 1 in the table is
sin (2x) = sin (x+x)
The step 3 is
sin (2x) = 2 sine (x) cosine (x)
The step 2 is obtained by the trigonometric identity
sin (x+y) = sinx cosy + cosx siny
So,
sin (x+x) = sinxcosx+sinx cosx
sin (2x) = sin(x)cos(x) + sin(x)cos(x)

Answer:

Step-by-step explanation:
Sam and liam raced each other up and down the hill. Sam's avrage speed up hill was 1 mph, and his avrage speed down hill is 9 mph. Liam ran up and down the hill with the same speed 2 mph.If the path from the bottom of the hill is 1 mile long, how much time did it take the boys to finish-and who is the winner?
Answers
Answer:
a. i. 1.11 h ii. 1 h. b. Liam
Step-by-step explanation:
a.
i. Sam's time
We know distance d = vt where v = speed and t = time.
Since our distance here is the length of the path, d = 1 mile.
For Sam, his speed up the hill is v = 1 mph, so, the time it takes him to go uphill is t = d/v = 1 mi/1 mph = 1 h.
He goes down hill at a speed of v = 9 mph, so the time it takes him to go down hill is t = d/v = 1 mi/9 mph = 1/9 h = 0.11 h
So, the total time it takes him to complete the trip is t = 1 h + 0.11 h = 1.11 h
ii. Liam's time
For Liam, his speed both uphill and downhill is v = 2 mph, so, the time it takes to cover each trip is t = d/v = 1 mi/2 mph = 0.5 h.
So for both uphill and downhill trip, the total time is t' = 2 × 0.5 h = 1 h
b. Since Liam's time t' = 1 h < Sam's time t = 1.11 h, that is t' = 1h < t = 1.11 h, Liam is the winner.
