Question 2 of 10 What is the length of side s of the square shown below? 45 6 09 90° O A. 6 O B. 2 O C. 32 O D. 5 O E. 3 OF. 6-12
Answer:
C
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{s}{6}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2s = 6[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
s = 3[tex]\sqrt{2}[/tex] → C
What are the solutions of the equation (x + 2)^2+ 12(x + 2)-14=0? Use u substitution and the quadratic formula to solve
Answer:
Step-by-step explanation:
Obviously, we are letting u = x + 2. So what we have when we rewrite using this substitution is
[tex]u^2+12u-14=0[/tex] and we plug that into the quadratic formula with
a = 1, b = 12, c = -14:
[tex]u=\frac{-12+-\sqrt{12^2-4(1)(-14)} }{2(1)}[/tex] which can be simplified to
[tex]u=\frac{-12+-\sqrt{144+56} }{2}[/tex] and a bit more to
[tex]u=\frac{-12+-\sqrt{200} }{2}[/tex] and a tiny bit more to
[tex]u=\frac{-12+-10\sqrt{2} }{2}[/tex] and finally to
[tex]u=-6+-5\sqrt{2}[/tex] and plug back in for u:
x + 2 = -6 ± 5√2 and then subtract the 2 to get
x = -8 ± 5√2
It takes Priti 4 hours to drive from Ashdown to Bridgeton at an average speed of 50 mph. She then drives 30 miles from Bridgeton to Carton at an average speed of 40 mph. Assuming Priti doesn't stop, what is her average speed from Ashdown to Carton to 1 dp?
Answer:
Her average speed from Ashdown to Carton is approximately 48.4 mph
Step-by-step explanation:
The time and speed of the motion of Priti are as follows;
The time it takes Priti to drive from Ashdown to Bridgeton, t₁ = 4 hours
The average speed she drove from Ashdown to Bridgeton = 50 mph
The distance she drove from Bridgeton to Carton, d₂ = 30 miles
Her average speed from Bridgeton to Carton = 40 mph
The distance from Ashdown to Bridgeton, d₁ = 50 mph × 4 hours = 200 miles
The time it takes Priti to drive from Bridgeton to Carton, t₂ = 30 miles/(40 mph) = 0.75 hour
Average velocity, [tex]v_{ave}[/tex] = (Total distance traveled, Δd)/(Total time, Δt)
Δd = d₁ + d₂, Δt = t₁ + t₂
Δd = 200 miles + 30 miles = 230 miles
Δt = 4 hours + 0.75 hour = 4.75 hours
∴ The average velocity, [tex]v_{ave}[/tex] = (230 miles)/(4.75 hours)
∴ [tex]v_{ave}[/tex] = (920/19) mph
Her average speed from Ashdown to Carton, rouded to 1 d,p, [tex]v_{ave}[/tex] ≈ 48.4 mph

Problem 5
d = 29 = diameter
r = d/2 = 29/2 = 14.5 = radius
SA = surface area of sphere
SA = 4*pi*r^2
SA = 4*pi*(14.5)^2
SA = 841pi
SA = 841*3.14
SA = 2,640.74 square inches
To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.
2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft
Answer: 18.3 square feet (approximate)=====================================
Problem 6
d = 10.7 = diameter
r = d/2 = 10.7/2 = 5.35 = radius
L = 22.3 = slant height
SA = surface area of the cone
SA = pi*r^2 + pi*r*L
SA = pi*(5.35)^2 + pi*5.35*22.3
SA = 147.9275pi
SA = 147.9275*3.14
SA = 464.49235
Answer: 464.49235 square cm (approximate)Combine these radicals. -6v100 + V36
Answer:
-54
Step-by-step explanation:
[tex]-6\sqrt{100} +\sqrt{36}[/tex]
-6 * 10 + 6
-60 + 6
= -54
100 = 50 *2
= 25 * 2 * 2

= [tex]5^{2} *2^{2}[/tex]
5 * 2 = 10

use the following arithmetic sequence and the formula an=a1+(n-1)d to answer the questions below 123,116,1099,102,95.
part 1. find the value of each of the following
part 2/ find the explicit formula, show work. part 3.
part 3. use the explicit formula you found from part 2 to find the value of the 100th term in the sequence show your work!
Answer:
see below
Step-by-step explanation:
123,116,109,102,95.
First find the common difference
d = 116 - 123 = -7
We are subtracting 7 each time
Using the formula
a1 = 123
d=-7
an = 123+ (n-1)(-7)
We need to find the 100th term
Let n = 100
a100 = 123 +(100-1) (-7)
= 123+(99)(-7)
= 123-693

Answer:
the answer would be 270
Step-by-step explanation:
i can explain later:
since x = 5, you plug it in f = 4x +7, and you get f = 27 and since 1/2x is in the denominator, it will flip over and become 2x. 2x is 10, so you multiply f by g and get 270 which is if f/g(5) is the question.
The root for an equation x²-px+6=0 ls 3. Find the value of p
Jawapan / Anne
IP
Answer:
5
Step-by-step explanation:
Given that 3 is a root of the equation x²-px+6=0
To find the value of p, substitute 3 into the equation for x
Hence x²-px+6=0
becomes
3^2 - 3p + 6 = 0
9 -3p + 6 = 0
collect like terms
-3p = -9 - 6
-3p = -15
Divide both sides by -3
p = -15/-3
p = 5
a hiker in africa discovers a skull that contains 41% of its original amount of c-14. find the age of the skull to the nearest year
9514 1404 393
Answer:
7371 years
Step-by-step explanation:
The half-life of Carbon-14 is reportedly about 5730 years. Then the exponential decay equation can be written as ...
f = (1/2)^(t/5730)
where f is the fraction remaining after t years.
Taking logarithms and solving for t, we find ...
log(f) = (t/5730)log(1/2)
t = 5730·log(f)/log(1/2)
For the fraction f = 0.41, the age is approximately ...
t = 5730·log(0.41)/log(1/2) ≈ 5730·1.286304 ≈ 7371 . . . years
The age of the skull could be estimated to be 7371 years.
For the angle 0 = 150° moving counter-clockwise in standard position, determine which
primary trigonometric ratio is positive.
Answer: Start at the positive
x
-axis, then rotate left by the desired angle.
Explanation-
Standard position means the first arm of the angle is the positive
x
-axis, and the other arm is placed by rotating counter-clockwise from there, by the amount of the angle.
As a basic example, the symbol
∠
is about a 45° angle in standard position.
To get a feel for where the second arm (called the "terminal arm") will go, remind yourself that the axes themselves meet each other at 90°.
If our angle was 90°, the terminal arm would be on the positive
y
-axis.
If our angle was 180°, it would be on the negative
x
-axis.
Wait! 180° is more than 150°, so our angle is somewhere in quadrant 2. In fact, 150° is 2/3 of the way between 90° and 180°, so our terminal arm will be 2/3 of the way into quadrant 2.

Step-by-step explanation:
The formula to figure this out is
[tex]C=66.99(1-.2)[/tex] where .2 is 1/5 in decimal form. What this means is that you may be saving 1/5 but you're still spending 4/5.
C = 66.99(.8) so

Consider the sequence 2/4, 3/5, 4/6, 5/7,... Which statement describes the sequence?
The sequence diverges.
The sequence converges to 0.
The sequence converges to 1.
The sequence converges to [infinity].
Answer:
The sequence converges to 1.
Step-by-step explanation:
Sequence 2/4, 3/5, 4/6, 5/7
This sequence can be summarized as:
[tex]\sum_{n=0}^{\infty} \frac{n+2}{n+4}[/tex]
To test if it converges, we can calculate the limite of [tex]\frac{n+2}{n+4}[/tex] as n goes to infinite.
Limit:
[tex]\lim_{n \rightarrow \infty} \frac{n+2}{n+4}[/tex]
Considering only the terms with the highest exponent in the numerator and the denominator:
[tex]\lim_{n \rightarrow \infty} \frac{n+2}{n+4} = \lim_{n \rightarrow \infty} \frac{n}{n} = \lim_{n \rightarrow \infty} 1 = 1[/tex]
Thus, the sequences converges to 1.
