Miguel eats a meal at a restaurant and leaves a 15 % tip for the server. The cost of the meal without the tip is p dollars. Which expressions represent the total cost, in dollars, of the meal and the tip? Select ALL that apply.
Answer:
B,D, and E
Step-by-step explanation:
it's 15% so it would have to be either as a fraction or decimal answer B is a fraction. And D and E are both decimals so you add your percent to your p which is something.
The expressions A, D, and E represent the total cost of the meal and the tip.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The cost of the meal plus the tip is equal to the cost of the meal plus 15% of the cost of the meal. It can represent this in several ways:
A. 1.15p
D. p + 0.15p
E. p + 1.15p
All of these expressions represent the total cost of the meal and the tip.
Option B, 100P/15, does not represent the total cost of the meal and the tip.
Option C, p + 15, represents the cost of the meal plus a flat fee of 15 dollars, not 15% of the cost of the meal, so it does not represent the total cost of the meal and the tip.
Therefore, the correct answers are A, D, and E.

Simone is four years older than her sister Olivia. Their combined ages is 28. What are their ages. Show all of your work
Answer:
Simone is 16 and Olivia 12 years old.
Step-by-step explanation:
"Simone is four years older than her sister Olivia."
(1) Simone age = Olivia age + 4
"Their combined ages is 28."
(2) Simone age + Olivia age = 28
→ We can substitute from the first equation (1) Simone age with Olivia age + 4 into the second equation (2)
Simone age + Olivia age = 28
Olivia age + 4 + Olivia age = 28, subtract 4 from both sides
Olivia age -4 +4 + Olivia age = 28 - 4
2· Olivia age = 24 , divide both sides by 2
Olivia age = 24/2
Olivia age = 12 years old
→ From the first equation (1) we have:
Simone Age = Olivia age + 4 = 12 + 4 = 16 years old
Check our answer:
"Their combined ages is 28 "
12 + 16 = 28 ✅

The Undefined term is csc(3pi) and sec(-pi/2) .
What is Trigonometry?The area of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
As, Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to 0. The value of sin (pi) is 0, so the cosecant of pi must be undefined.
Thus, csc(3pi) is undefined

There are many ways to solve a quadratic equation (factoring, quadratic formula, completing the square).
Solving this equation by factoring is the easiest. Factoring with a leading coefficient greater than one can be difficult and there are many ways to accomplish it. The way I'm going to do it is to first find the factors of [tex]4x^2[/tex] and then the factors of 11. And then multiply across, add the middle terms (derived from multiplying) and try to make it equal 24x.
[tex]4x^2[/tex]: 24x 11:
2x 22x 11
2x 2x 1
24x (works)
I'll then take the factors diagonal. (2x+1)(2x+11)=0

Answer:
[tex]x = -12[/tex]
Step-by-step explanation:
Step 1: Add 1/4x to both sides
[tex]-\frac{1}{4}x - 12 = x + 3[/tex]
[tex]-12 - \frac{1}{4}x + \frac{1}{4}x = x + 3 + \frac{1}{4}x[/tex]
[tex]-12 = \frac{5}{4}x + 3[/tex]
Step 2: Subtract 3 from both sides
[tex]-12 - 3 = \frac{5}{4}x + 3 - 3[/tex]
[tex]-15 = \frac{5}{4}x[/tex]
Step 3: Multiply both sides by 4/5
[tex]-15*\frac{4}{5}=\frac{5}{4}x * \frac{4}{5}[/tex]

Answer:
y = e·x
Step-by-step explanation:
The equation of a line tangent to a curve at a point is conveniently written in the point-slope form. The slope is the derivative of the function at the point. For your function, the rules applicable to products and exponential functions apply.
__
y = (e^x)(x^2 -2x +2
y' = (e^x)(x^2 -2x +2) +(e^x)(2x -2) . . . . . (uv)' = u'v +uv', (e^x)' = e^x
y' = (e^x)x^2 . . . . . simplify
For x=1, the slope is ...
y' = (e^1)(1^2) = e
__
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -e = e(x -1) . . . . . . . line with slope 'e' through point (1, e)
y = e·x -e +e . . . . . add e
y = e·x . . . . . . . . . . equation of the tangent line

can someone explain to me how to get 338 root 2 as the answer
Answer:
13√2
Step-by-step explanation:
The square root of 338 is expressed as √338 in the radical form and as (338)½ or (338)0.5 in the exponent form. The square root of 338 rounded up to 5 decimal places is 18.38478. It is the positive solution of the equation x2 = 338. We can express the square root of 338 in its lowest radical form as 13 √2.
√338 = √13^2x2 = V13^2 x √2 = 13√2
13√2 = 13 x 239/169 = 239/13 = 18.385
How to Crammers Rule to find k in this equation
Answer:
k = -1/2 or 2
Step-by-step explanation:
For equations ...
ax +by +c = 0
dx +ey +g = 0
Cramer's Rule tells you the solutions are ...
x = (-ce +gb)/(ae -db)
y = (-ga +dc)/(ae -db)
In order for these equations to be consistent, the solution for any pair of them must be the same. It is sufficient for us to find 'k' such that the values of x are the same.
__
first and third equations
x = (-1·7 +1·(k+1))/(1·7 -3·(k+1)) = (k -6)/(4-3k)
second and third equations
x = (3·7 +1·5)/(2k·7 -3·5) = 26/(14k -15)
__
For these values to be the same, we must have ...
(k -6)/(4-3k) = x = 26/(14k -15)
(k -6)(14k -15) = (4 -3k)(26) . . . . . cross multiply
14k² -99k +90 = -78k +104 . . . . . simplify
14k² -21k -14 = 0 . . . . . . . . . . . . . put in standard form
7(2k +1)(k -2) = 0 . . . . . . . . factor
The solutions are the values of k that make the factors zero: k=2, k=-1/2.
These equations will be consistent if k = -1/2 or k = 2.

Additional comment
Using our above expression for x, we can find the value of x for the solution x = -1/2 to be ...
x = 26/(14(-1/2) -15) = 26/(-22) = -13/11
The first equation tells us the corresponding value of y will be ...
x +(-1/2 +1)y +1 = 0
y = -2(x+1) = -2(-13/11 +11/11) = 4/11
For k = -1/2, (x, y) = (-13/11, 4/11).
The attached graph shows the solution for k=2.
For k = 2, (x, y) = (2, -1).
