At the beginning of May. Alice's checking account balance was $752. She wrote checks for $142, $37 and $172. She deposite $40, $80 and $35. What was her balance at the end of the month?​

Answers

It’s 556 because u subtract 142, 37, and 172 to 752 then you add 40, 80, and 35

Answer:

$556

Step-by-step explanation:

$752 - $142 = $610

$610 - $37 = $573

$573 - $172 = $401

$401 + $40 = $441

$441 + $80 = $521

$521 + $35 = $556

Writing checks takes money out so you subtract.

Depositing money means putting in which means you add.

2p+5+3=180 HELPPPPPP

Answers

Answer:

this one is actually not that hard. the answer is around 2p = 125

Step-by-step explanation:

Answer:

p = 35

Step-by-step explanation:

2p + 5 + 3p = 180 (Linear Pair)

=> 5p + 5 = 180

=> 5p = 180 - 5

=> 5p = 175

=> p = 175/5

=> p = 35

Solve the equation: -42 + w = 5

Answers

Hey there!

-42 + w = 5

w - 42 = 5

ADD 42 to BOTH SIDES

w - 42 + 42 = 5 + 42

CANCEL out: -42 + 42 because it gives you 0

KEEP: 5 + 42 because it helps you solve for the w-value

NEW EQUATION: w = 5 + 42

SIMPLIFY IT!

w = 47

Therefore, your answer is: w = 47

What is the vertex of the graph of this function?
v = - (x + 2)(x+4)

Answers

Answer:

(-3,1)

Step-by-step explanation:

Hope this helps:)

9514 1404 393

Answer:

  (-3 1)

Step-by-step explanation:

The x-intercepts of the function are the values of x that make the factors zero: x = -2, x = -4. The x-coordinate of the vertex is halfway between these values:

  x = (-2 +(-4))/2 = -6/2 = -3

The y-coordinate of the vertex is the function value at that x-coordinate:

  y = -(-3+2)(-3+4) = -(-1)(1) = 1

The coordinates of the vertex of the graph are (-3, 1).

I need this TODAY or I’m so unbelievably screwed i need to know how to do these kind of table graphs really quickly i have a test tomorrow and its worth 90 percent of my grade also If you could tell me how to get slope that would make my day and night.
Thank you. And if you can tell me how to find slope that would be great.

Answers

Answer: Hey, getting slope is actually really easy!

Step-by-step explanation: So, if you’re given 2 sets of number such as (2,5) or (-7,3) then you just take them and you have to realize that 2 is x and 5 is y. also that -7 is x2 and 3 is y2. so then you use this formula (y2-y1 / x2-x1) this will give you the slope!! here’s an example using the points i said earlier: 3-5 / -7-2. so it would be 2/-9 for the slope! also i’d they only give you one point and the y intercept then you can just use the one point and then make the y intercept have a 0. so id the y intercept is 9 then the ordered pair would be (0,9) Good Luck! and let me know if you need to know how to graph the slope:)

Answer:

B

Step-by-step explanation:

3 + f = 14 [tex]\frac{2}{7}[/tex] ← change to improper fraction

3 + f = [tex]\frac{100}{7}[/tex] ( multiply through by 7 to clear the fraction )

21 + 7f = 100 ( subtract 21 from both sides )

7f = 79 ( divide both sides by 7 )

f = [tex]\frac{79}{7}[/tex] = 11 [tex]\frac{2}{7}[/tex] → B

Answer:

B. [tex]f=11\frac{2}{7}[/tex]

Step-by-step explanation:

We have the equation 3 + f = 14 2/7

We need to get f alone, doing so is subtracting three from both sides:

3 + f = 14 2/7

-3     = -3

14 2/7 - 3 = [11 2/7]

Leaving us with f = 11 2/7

This is B.

Give possible values for the measures of angles A and C if ABC is a right triangle.

Answers

Answer:

0 < A < 90

0 < C < 90

Step-by-step explanation:

If B is the right angle of the triangle, then the sum of the other angles, A and C, must equate 90° since all angles in a triangle sum to 180°:

A + C = 90

A and C could both be anything between 0 and 90, but they must satisfy the equation above:

0 < A < 90

0 < C < 90

(c). Under a set of controlled laboratory conditions, the size of the population P of a certain bacteria culture at time t (in seconds) is given by the function P(t)= 3t² +3e' +10, t≥0.

(1) What is the size of the population after 1 minute?

(ii) Find the average rate of change of P at t = 2 and t = 6?

(iii) How fast is the size of the population changing after 1 minute?

[Verify your answer by MATHEMATICA and attach the printout of the commands and output

Answers

(i) Since P(t) gives the population of the culture after t seconds, the population after 1 second is

P(1) = 3•1² + 3e¹ + 10 = 13 + 3e ≈ 21.155

In Mathematica, it's convenient to define a function:

P[t_] := 3t^2 + 3E^t + 10

(E is case-sensitive and must be capitalized. Alternatively, you could use Exp[t]. You can also specify that the argument t must be non-negative by entering a condition via P[t_ ;/ t >= 0], but that's not necessary.)

Then just evaluate P[1], or N[P[1]] or N <at symbol> P[1] or P[1] // N to get a numerical result.

(ii) The average rate of change of P(t) over an interval [a, b} is

(P(b) - P(a))/(b - a)

Then the ARoC between t = 2 and t = 6 is

(P(6) - P(2))/(6 - 2) ≈ 321.030

In M,

(P[6] - P[2])/(6 - 2)

and you can also include N just as before.

(iii) You want the instantaneous rate of change of P when t = 60 (since 1 minute = 60 seconds). Differentiate P :

P'(t) = 6t + 3e^t

Evaluate the derivative at t = 60 :

P'(60) = 6•60 + 3e⁶⁰ = 360 + 3e⁶⁰

The approximate value is quite large, so I'll just leave its exact value.

In M, the quickest way would be P'[60], or you can differentiate and replace (via ReplaceAll or /.) t with 60 as in D[P[t], t] /. t -> 60.

Answers

Answer:

x = 5  or   x = 1

Step-by-step explanation:

 x² - 6x + 7 = 0

x² - 6x = -7

x² - 6x + 9 = -7 + 9      1/2 of the x term than square it and add it the both sides.

(x - 3)(x - 3) = 2

( x -3)² = 2

[tex]\sqrt{(x - 3)^2[/tex] = [tex]\sqrt{2}[/tex]

(x -  3) = ± 2

x - 3 = 2  or  x - 3 = -2

x = 5     or  x = 1

The tangent of 62 degree is 24/7 because tan is the ratio of side opposite to the angle to side adjacent to the angle option (A) is correct.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a right angle triangle shown in the picture with side length.

As we know the tan is the ratio of side opposite to the angle to side adjacent to the angle.

tan62 = 24/7

Thus, the tangent of 62 degree is 24/7 because tan is the ratio of side opposite to the angle to side adjacent to the angle option (A) is correct.
