I hope this helped! :)Angelique travels 75 miles. Jamila travels 115 kilometres. Show that Angelique has travelled futher than Jamila.
Answer:
Angelique has traveled further than Jamila by about 6 km.
Step-by-step explanation:
Make them the same unit (I will make them both kilometers)
There is about 1.609 km in 1 mile
75 miles * 1.609 km/1 mile = 120.675
120.675 km>115 km
Find the inverse of f(x)
15-20/3
Answer:
C. (-3x+15)/2
Step-by-step explanation:
y = (15-2x)/3
To find the inverse, exchange x and y
x = (15-2y)/3
Solve for y
Multiply each side by 3
3x = (15-2y)/3 *3
3x= 15-2y
Subtract 15 from each side
3x-15 = 15-2y-15
3x-15 = -2y
Divide by -2
(3x-15)/-2 = -2y/-2
(-3x+15)/2 = y
Evaluate the equation
Answer:
3 +4 i
Step-by-step explanation:
x + sqrt(yz)
Let x = 3 y=2 and z = -8
3 + sqrt(2*-8)
3+ sqrt(-16)
3 + sqrt(16) sqrt(-1)
We know sqrt(-1) = i
3 +4 i
Write down the missing number number 86 493 -...... =8420
Answer:
78,073
Step-by-step explanation:
Subtract 8,420 from 86,493...86,493-8,420=78,073 is the answer
Double check by using inverse operations...78,073+8,420=86,493
It is correct, as I ended up with 86,493, the starting number of the equation.
What is the wavelength of light with 5.53 x 10-19 J of energy? (The speed of
light in a vacuum is 3.00 x 10 m/s, and Planck's constant is 6.626 10-34

A. 399 nm
B. 278 nm
C. 250 nm
D. 359 nm
Answer:
D. 359 nm
[tex]{ \boxed{ \bf{ energy = \frac{hc}{ \lambda} }}} [/tex]
lambda is the wavelength
c is the speed of light
h is the Planck's constant

Graph the equation
y = 5x
Use the graphing tool to graph the line.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
You want a line that goes through (0, 0) and has a slope of 5. That means it will also go through (1, 5) and (2, 10), for example. I like the attached graphing tool because it will draw the graph directly from the equation.

Find the product: 12 x 3/5 =
Answer:
12 x 3/5 = 7 1/5
Step-by-step explanation:
12 x 3/5
Add 1 below 12 as a denominator to make it an improper fraction
= 12/1 x 3/5
Multiply numerators from both fractions as long as the denominators:
12 x 3 = 36
1 x 5 = 5
12/1 x 3/5 = 36/5
36/5 SIMPLIFIED IS 7 1/5
Hope this helps!
Answer:
36/5 = 7.2 = 7 1/5
Step-by-step explanation:
12 x 3/5
Change 12 into fraction form to make it easier.
12/1 x 3/5
Now multiply the numerators and the denominators.
12 x 3 = 36
1 x 5 = 5
12/1 x 3/5 = 36/5
If you don't want the answer as an improper fraction, 36/5 = 7.2 which is also equal to 7 1/5

Consider the function f(x) = square root of x+3
a. In your own words, explain the meaning of f'(2).
b. Now using mathematical notation, write f'(2) as a limit.
(Plz hurry and help meee)
Step-by-step explanation:
f'(x) is usually used in calculus to denote the first derivative of f(x) so f'(2) will simply be the first derivative of f(2).
f(x)=x+3
f'(x)=1
thus x does affect the first derivative and your answer for f'(x)=1

Answer:
x = 1/2
Step-by-step explanation:
8(-2x+1) =0
Divide each side by 8
-2x+1 = 0
Add 2x to each side
-2x+1+2x = 2x
1 = 2x
Divide by 2
1/2 = 2x/2
1/2 =x
Answer:
1/2
Step-by-step explanation:
8(-2x+1)=0
Use distributive property first
-16x+8=0
Subtract 8 on both sides
-16x=-8

Evaluate the line integral, where C is the given curve. C (x yz) dx 2x dy xyz dz, C consists of line segments (3, 0, 1) to (4, 3, 1) and from (4, 3, 1) to (4, 5, 4)
Split up C into two component paths C₁ and C₂, where each line segment is respectively parameterized by
r₁(t) = (1 - t ) (3i + k) + t (4i + 3j + k) = (t + 3) i + 3t j + k
r₂(t) = (1 - t ) (4i + 3j + k) + t (4i + 5j + 4k) = 4i + (2t + 3) j + (3t + 1) k
both with 0 ≤ t ≤ 1.
It's a bit unclear what function you're supposed to integrate (looks like xyz ?) so I'll give a more general result. The line integral of a scalar function f(x, y, z) along the given path C is
[tex]\displaystyle \int_C f(x,y,z)\,\mathrm ds = \int_{C_1}f(\mathbf r_1(t))\left\|\frac{\mathrm d\mathbf r_1}{\mathrm dt}\right\|\,\mathrm dt + \int_{C_1}f(\mathbf r_2(t))\left\|\frac{\mathrm d\mathbf r_2}{\mathrm dt}\right\|\,\mathrm dt[/tex]
We have
dr₁/dt = i + 3j ==> || dr₁/dt || = √(1² + 3²) = √10
dr₂/dt = 2j + 3k ==> || dr₂/dt || = √(2² + 3²) = √13
Then the integrals reduce to
[tex]\displaystyle \int_0^1 \left(\sqrt{10}\,f(t+3,3t,1) + \sqrt{13}\,f(4,2t+3,3t+1)\right)\,\mathrm dt[/tex]
If indeed f(x, y, z) = xyz, then we have
[tex]\displaystyle \int_0^1 \left(3\sqrt{10}\,t(t+3) + 4\sqrt{13}\,(2t+3)(3t+1)\right)\,\mathrm dt = 11\sqrt{\frac52}+42\sqrt{13}[/tex]

In order to encourage pema to do her mathematics problems, her dad promise to pay Nu 5 for every problem She gets right, but he would take away Nu 3 for any moblem she missed. After working 20 problems, Pema was paid Nu 6o. How many problems did she solve correctly?
The solution to he word problem leading to simultaneous equation is as follows;
The number of problems Pema is able to solve correctly is 15 problems
The method by which we arrived at the above value is as follows:
The given parameters of the question are;
Amount Pema's dad promise to pay her for every problem she gets right = Nu 5
Amount he would take away for any problem missed = Nu 3 (Therefore, Nu -3)
Amount Pema was paid after working 20 problems = Nu 60
Solution;
Let x represent the number of problems she gets right (solves correctly), and let y represent the number of problems she missed, we have the following system of (simultaneous) equations;
x + y = 20...(1)
5·x - 3·y = 60...(2)
Multiplying equation (1) by 3 and adding the result to equation (2) gives;
3 × (x + y = 20) ⇒ 3·x + 3·y = 60
[tex]{}[/tex] 5·x - 3·y = 60
+ 3·x + 3·y = 60

Three jackets cost as much as five shirts. Each jacket costs $16 more
than each shiri. What is the cost of one shirt?
Answer:
$3.20
Step-by-step explanation:
Divide the number 16 (as in the cost per Jacket) by 5. (The amount of shirts you could buy with $16)
Then once you have divided 16 by 5, your answer should be 3.2, so the cost of one shirt is $3.20

(A) f(x) = 7 is constant, so f(x + h) = 7, too, which makes f(x + h) - f(x) = 0. So f'(x) = 0.
(B) f(x) = 5x + 1 ==> f(x + h) = 5 (x + h) + 1 = 5x + 5h + 1
==> f(x + h) - f(x) = 5h
Then
[tex]\displaystyle f'(x) = \lim_{h\to0}\frac{5h}h = \lim_{h\to0}5 = 5[/tex]
(C) f(x) = x ² + 3 ==> f(x + h) = (x + h)² + 3 = x ² + 2xh + h ² + 3
==> f(x + h) - f(x) = 2xh + h ²
[tex]\implies\displaystyle f'(x) = \lim_{h\to0}\frac{2xh+h^2}h = \lim_{h\to0}(2x+h) = 2x[/tex]
(D) f(x) = x ² + 4x - 1 ==> f(x + h) = (x + h)² + 4 (x + h) - 1 = x ² + 2xh + h ² + 4x + 4h - 1
==> f(x + h) - f(x) = 2xh + h ² + 4h
[tex]\implies \displaystyle f'(x) = \lim_{h\to0}\frac{2xh+h^2+4h}h = \lim_{h\to0}(2x+h+4) = 2x+4[/tex]
