A dress that costs $66.99 is on sale for 1/5 off. What is the sale price of the dress? Round your answer to the nearest cent.
Answer:
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
Cost = $53.59
explain everything you know about y=x^2-5x-6
y = x^2 -5x-6 is a quadratic equation.
On a graph, rather than a straight line, this type of equation forms what is known as a parabola, which means it goes one direction and then makes almost like a U-turn.
The point in which the parabola (as mentioned before) changes direction is called the vertex.
Specifically, y = x^2 -5x-6 has exactly 2 solutions. This means that there are 2 different possible answers to this equation.
The solutions, or roots, to this equation are x= 6 and x= -1.
If you look at the graph for this equation, the parabola opens upwards like a U, and the vertex is ( 5/2, -49/4).
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

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.

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
= -570

Carlos keeps his cards in an album. So far he has lots of full pages plus another 48 cards ready to go in. Altogether, he has more than 500 cards. If each page holds 20 cards, write an inequality that represents how many pages of cards Carlos might have. Solve the inequality. Guys how do i do this, this is hard, pls pls help.
Answer:
x ≥ 22.6 pages
Step-by-step explanation:
Each page = 20 cards
Cards ready to go in = 48
Let x = number of pages of cards Carlos might have
The inequality:
20x + 48 ≥ 500
20x ≥ 500 - 48
20x ≥ 452
x ≥ 452 / 20
x ≥ 22.6 pages

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)=====================================

SA = pi*(5.35)^2 + pi*5.35*22.3

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.

What is the probability of living another year for a woman who is 73 years old ?
a) 0.951716
b) 0.968048
c) 0.980413
d) 0.991871
Answer:
0.980413
Step-by-step explanation:
The table for the deaths and death rate per 100,000 population is attached below ;
73 years fall in the 65 - 74 years category ; with 1958.7 deaths (Female)
Hence, the probability of living another year is :
Number of deaths per 100,000 population ;
P(death) = 1958.7 / 100,000 = 0.019587
Probability of living another year = 1 - P(death)
1 - 0.019587 = 0.980413

C. 0.980413

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

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.

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
