If a recipe called for 16 ounces of flour. How many cups would you use

Answer: OPTION A

Step-by-step explanation:

Apply the Quadratic formula, which is:

[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

In this case:

[tex]a=1\\b=-6\\c=58[/tex]

Then, you must susbtitute these values into the quadratic formula, as shown below:

[tex]x=\frac{-(-6)\±\sqrt{(-6)^2-4(1)(58)}}{2*1}[/tex]

[tex]x=\frac{6\±\sqrt{-196}}{2}[/tex]

Keep on mind that [tex]i=\sqrt{-1}[/tex], then you can rewrite it as following:

[tex]x=\frac{6\±14i}{2}\\\\\\x=\frac{2(3\±7i)}{2}\\\\x=3\±7i\\\\x_1=3+7i\\x_2=3-7i[/tex]

Answer:

A. {[tex]3+7i,3-7i[/tex]}

Step-by-step explanation:

The given equation  is  [tex]x^2-6x+58=0[/tex]

Use the quadratic formula with a=1,b=-6 and c=58

Recall the quadratic formula;

[tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

We substitute the given values to get;

[tex]x=\frac{--6\pm \sqrt{(-6)^2-4(1)(58)} }{2(1)}[/tex]

[tex]x=\frac{6\pm \sqrt{36-232} }{2}[/tex]

[tex]x=\frac{6\pm \sqrt{-196} }{2}[/tex]

Recall that;

[tex]\sqrt{-1}=i[/tex]

[tex]x=\frac{6\pm 14i}{2}[/tex]

[tex]x=3\pm 7i[/tex]

[tex]x=3+7i[/tex] or [tex]x=3-7i[/tex]

Answer:

so a sub n=2.3+(n-1)0.3

That's in an arithmetic sequence

Answer:

Option C is the answer.

Step-by-step explanation:

Given arithmetic series is 2.3 + 2.6 +2.9 + ......... 5 terms

Since this series is an arithmetic series so explicit formula of series will be [tex]\sum_{n=1}^{n}[a+(n-1)d][/tex] where a is the first term, d is the common difference and n is the number of term.

Therefore, we replace the values a = 2.3, and d = (2.6 - 2.3) = (0.3)

expression will be [tex]\sum_{n=1}^{n}[2.3+(n-1)(0.3)][/tex]

[tex]\sum_{n=1}^{n}[2.3+(0.3)n-0.3][/tex]

[tex]\sum_{n=1}^{n}[2+(0.3)n][/tex]

Option C is the answer.

Answer:

Step-by-step explanation:

For this problem, point slope form would be the easiest.

Point Slope Form- y-y1 = m(x-x1)

In this case, y1 is 3, x1 is 5, and m would be the slope which is -4.

y-3=-4(x-5)

This is how to write an equation for the problem.

Answer:

[tex]\large{\boxed{y-3=-4(x-5)-\text{point-slope form}}\\\boxed{y=-4x+23}}[/tex]

Step-by-step explanation:

The equation of a line in point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

(x₁, y₁) - point

We have the slope m = -4 and the point (5, 3). Substitute:

[tex]y-3=-4(x-5)[/tex]       use distributive property

[tex]y-3=-4x+(-4)(-5)[/tex]

[tex]y-3=-4x+20[/tex]       add 3 to both sides

[tex]y=-4x+23[/tex]

Answer:

120

Step-by-step explanation:

! means 3*2*1

so 6*1=6*5*4*3*2*1

6=720

720/6=120

factorial of n is given as

n! = n × (n-1) × (n-2)× . . . . . × 1

so lets solve it

6! = 6 × (6-1) × (6-2) × ( 6-3)×(6-4)×(6-5)

= 6×5×4×3×2×1

=720

similarly

3! = 3×2×1 =6

2!= 2×1= 2

3! × 2! = 6×2= 12

P(x < 5) = 0.70

Step-by-step explanation:

Note:  The area under a probability "curve" must be = to 1.

Finding the sub-area representing x < 5 immediately yields the desired probability.

Draw a dashed, vertical line through x = 5.  The resulting area, on the left, is a trapezoid.  The area of a trapezoid is equal to:

 (average length)·(width, which here is:

Answer:

[tex]N=2.1990232556 \times 10^{13}[/tex]

Step-by-step explanation:

Given : Brett has been studying a type of bacteria that doubles every month. Originally, there were 5 bacterial cells.

To Find: He wants to know how many there will be after 42 months?

Solution:

Since we are given that initially there were 5 bacterial cells.

Bacteria doubles every month

Let n denotes the number of months .

Function becomes : [tex]N=N_0(2)^n[/tex]

[tex]N_0[/tex] = initial amount

N = amount after n months

So, [tex]N=5(2)^n[/tex]

Substitute n = 42

[tex]N=5(2)^{42}[/tex]

[tex]N=2.1990232556 \times 10^{13}[/tex]

Thus there will be [tex]2.1990232556 \times 10^{13}[/tex] bacteria after 42 months.

Answer: Option 'D' is correct.

Step-by-step explanation:

Let the number of adult tickets sold be 'a'.

Let the number of students tickets sold be 's'.

Cost of an adult ticket = $10.00

Cost of a student ticket = $7.50

According to question, it becomes,

[tex]10.00a+7.50s[/tex]

Hence, option 'D' is correct.

The expression that represents the amount of money collected at the door from the ticket sales is $10a + $7.50s

The total amount collected at the door is the sum of the total cost of adult tickets and children tickets

Total cost of adults ticket = cost per ticket x total number of adults tickets sold

$10 x a = $10a

Total cost of children's ticket = cost per ticket x total number of children tickets sold

$7.50 x s = $7.50s

The total amount collected at the door  = $10a + $7.50s

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

To find x subtract the sum of the 2 given angles from 180, that is

x = 180° - (32 + 52)° = 180° - 84° = 96°

-------------------------------------------------------

x and y form a straight angle, hence

y = 180 - x = 180° - 96° = 84°

------------------------------------------------------

To find z subtract the sum of the 2 angles from 180

z = 180° - (55 + y)° = 180° - (55 + 84)° = 180° - 139° = 41°

--------------------------------------------------------

x = 96°, y = 84°, z = 41° → A

Answer:

A. (2x-3)/2

Step-by-step explanation:

Performing the long division indicated by the perimeter expression, you find ...

perimeter = (2x -3) + (10x +6)/(x^2 +2x)

Comparing this to the formula for the perimeter ...

perimeter = 2W +2L

where L is said to be of the form (ax +b)/(x^2 +2x)

we can match terms in the perimeter expression to see that ...

2W = 2x -3

2L = (10x +6)/(x^2 +2x)

The problem doesn't ask for it, but we can see that (a, b) = (5, 3). We can also see that ...

W = (2x -3)/2 . . . . . . . matches choice A

Answer:

[tex]\frac{1}{2}(\frac{1}{4}^x)[/tex]

Step-by-step explanation:

To find the function, compare the y values. Notice that each y value decreases by being divided by 4. This means the base of the exponential is 1/4.

To find the initial value, consider the point (0,0.5). When 1/4 is raised to the 0 power, the value is 1. This leaves that the initial value is 1/2 since 1/2*1 = 0.5.

The function is [tex]\frac{1}{2}(\frac{1}{4}^x)[/tex].

Answer:

The required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].

Step-by-step explanation:

The general exponential function is

[tex]f(x)=ab^x[/tex]           .... (1)

where, a is the initial value and b is growth factor.

From the given table it is clear that the function passes through the points (0,0.5) and (-1,2). It means the equation of function must be satisfied by the points (0,0.5) and (-1,2).

Substitute f(x)=0.5 and x=0 in equation (1), to find the value of a.

[tex]0.5=ab^0[/tex]

[tex]0.5=a[/tex]

The value of a is 0.5.

Substitute a=0.5, f(x)=2 and x=-1 in equation (1), to find the value of b.

[tex]2=(0.5)b^(-1)[/tex]

[tex]2=\frac{0.5}{b}[/tex]

[tex]2b=0.5[/tex]

Divide both sides by 2.

[tex]b=\frac{0.5}{2}[/tex]

[tex]b=0.25[/tex]

The value of b is 0.25.

Substitute a=0.5 and b=0.25 in equation (1).

[tex]f(x)=0.5(0.25)^x[/tex]

[tex]f(x)=\frac{1}{2}(\frac{1}{4})^x[/tex]

Therefore the required function is [tex]f(x)=\frac{1}{2}\left(\frac{1}{4}\right)^x[/tex].

Answer:

2650

Step-by-step explanation:

Given: 2648

Two significant figures means we need to round off to the nearest tens place.

In 2648, the tens place is 4

To round off the tens place, we need to look for the next digit that is right to tens place, which is 8

8 is greater than 5, so we need to add 1 with tens place (4 +1 = 5)

Therefore, it is 2650

Hope this will helpful.

Thank you.

2648 to two significant figures is 2700

The significant figures of a number are digits that carry meaning contributing to its measurement resolution. This includes all digits except all leading zeros

There are three rules determining how many significant figures are in a number:

For addition and subtraction use the following rules:

For multiplication and division use the following rule:

The given number is 2648

2648 can be written in two significant figures as 2700

2648 has four significant figures such as 2,6,4,8.

The second digit in the given number 2648 is '6'

Because the number 6 is greater than 5, therefore it can be rounded as '7'

Therefore, the number 2648 with four significant figures can be written as 2700 in two significant figures.

So 2700 has only two significant figures: 2 and 7.

Answer:

244.56

Step-by-step explanation:

Alice starts with x amount of money, and then spends 41.52 of it. This means that x-41.52 is equal to the amount of money Alice has left because spending 41.52 means that it is subtracted from the bank account. Thus, x-41.52=203.04 .

Using the additive property of equality, we can add 41.52 to both sides, resulting in x=244.56
