How do you graph the equation f(x)=10x+40??
Answers
y = mx + b
B is the y-intercept. In this equation the y intercept is 40. A y- intercept is where the graph crosses the y axis so at the point (0,40) the graph crosses the y axis.
M is the slope which is rise over run so if the slope was 10 (which it is) 10 is equivalent to 10/1 so you move up 10 units for every 1 unit you move across.
So to graph this equation, you would draw your first point at (0,40). For your next point, you would move right one unit, and up 10 units. Draw a point there which would be (1, 50). Hopefully you understand. For going left from the y intercept point, you would move left 1 and down 10.
Actual graph above.

Answers
A woman who is 5 feet 6 inches tall and weighs 175 pounds has a BMI of 28.2 and would be classified as overweight.
The Body Mass Index (BMI) is a tool commonly used to assess whether a person has a healthy weight relative to their height. To calculate BMI, you divide a person's weight in pounds by their height in inches squared and multiply by 703.
For a woman who is 5 feet 6 inches tall and weighs 175 pounds:
Height: 66 inchesWeight: 175 poundsThe calculation for BMI would be:
BMI = (175 / (66×66)) × 703
BMI = 28.2
According to the BMI weight status categories:
BMI between 25 and 29.9 is considered overweight, and a BMI of 30 or higher is considered obese.
Therefore, a woman who is 5 feet 6 inches tall and weighs 175 pounds would be classified as overweight.

but I am to restrict the function would it be \(\bf{x \ge 0}\)?
Answers
that is correct hmmmm, yes, I think the restriction is also correct, it has to be x > 0, because, the domain on the original, has a restriction of x⩾3, otherwise the radicand turns negative.
now, the graph of that original function is a parabola sideways opening to the right, if you include both sides of the vertex of the parabola, it will not pass the vertical-line-test and not be a function, but if you restrict it to only positive roots, so it'll only be on the 1st quadrant, then it functions ok.
that means, the range of the original function, has to stick to only 0 or positive root values, now, recall that the range of the original is the domain of the inverse. Therefore, the domain of the inverse, will have to stick to only 0 or positive values, since it's bound to the same restriction as the original's range.
notice the picture below of both, the dashed section is the positive range for each, if you include it, the original will fail the vertical-line-test, and the inverse will fail the horizontal-line-test.
recall that for a function to have an inverse, they both must pass the vertical and horizontal line test, or be a one-to-one functions.

Answer: The correct option is (B) 3.
Step-by-step explanation: We are given to find the length of the leg s in the triangle shown in the figure.
From the figure, we note that
the given triangle is a right-angled one, where
length of the hypotenuse, H = √18 units,

How do you find the x intercepts of a polynomial function with a zero constant?
Answers
To find the x-intercepts of a polynomial function, set y equal to zero and solve for x. Use the quadratic formula -b±sqrt(b²-4ac)/2a to solve, where a, b, and c are coefficients of the function.
Explanation:The 'x' intercepts of a function are the values of 'x' where 'y' equals zero. Take the given polynomial equation x² +0.0211x -0.0211 = 0; here a=1, b=0.0211 and c=-0.0211. We can solve this using the quadratic formula which states: x = -b ± sqrt(b² - 4ac) / 2a. Plugging the values in we get: x = -0.0211 ± sqrt((0.0211)² - 4(1)(-0.0211)) / (2*1).

In a standard deck of 52 playing cards, which king does not have a mustache?
Answers
Your answer would be:
King of hearts.
Hope This Helps You!
Good Luck :)
- Hannah ❤
The King of Hearts is the card without a mustache. Whether you should play a game where you draw cards for money depends on the expected value calculation. Understanding the difference between sampling with and without replacement is key in card probability problems.
Explanation:In a standard deck of 52 playing cards, the king without a mustache is the King of Hearts. Now, regarding the different scenarios involving card games with a standard deck:
When you play a game where drawing a face card wins you $30, and a non-face card makes you pay $2, you need to consider the expected value of the game. With 12 face cards and 40 non-face cards, your expected winnings would be (12/52) * $30 - (40/52) * $2, which may or may not be positive. You should calculate this to decide if you should play the game.When drawing two cards without replacement from a standard deck, the probabilities will change after the first draw since there are fewer cards remaining in the deck. You would create and use a tree diagram to calculate the precise probabilities of each combination.The probability of being dealt a bridge hand that does not contain a heart would require calculating the combinations of all possible non-heart cards from the remaining three suits.When comparing scenarios a. and b. above, scenario a represents sampling without replacement because once a card is drawn, it is not put back into the deck, whereas scenario b represents sampling with replacement as each card is put back before the next one is drawn.Two angles of an isosceles triangle measure 70° and x°. What is the sum of three possible values of x? A. 95 B. 125 C. 140 D. 165 E. 180
Answers
The sum of three possible values of x° in the isosceles triangle is 180°. The angles are 40°, 70°, and 70°. The correct answer is E. 180.
In an isosceles triangle, two angles are congruent (equal). So, if one angle is 70°, the other angle must also be 70°.
Let's denote the third angle as y°.
Since the sum of the angles in any triangle is 180°, we can write the equation:
70° + 70° + y° = 180°
Solving for y:
2 × 70° + y° = 180°
y° = 180° - 140°
y° = 40°
So, the three possible values of x° are 40°, 70°, and 70°.
Now, let's find the sum of these three possible values:
Sum = 40° + 70° + 70°
Sum = 180°
Therefore, the sum of three possible values of x° is 180°. The correct answer is E. 180.

The opening balance of one of the 31-day billing cycles for Lorenzo's credit card was $4100, but after 15 days Lorenzo made a payment of $2300 to decrease his balance, and it stayed the same for the remainder of the billing cycle. If his credit card's APR is 24%, how much more in interest would he pay for the billing cycle with the previous balance method than with the adjusted balance method? A.$83.57
B.$46.88
C.$36.69
D.$120.26
Answers
31 days = 7,400
15 days = payment of 4,900
16 days = 7,400 - 4,900 = 2,500
Method 1:
7,400 * 22% * 31/365 = 138.27
Method 2: adjusted balance
7,400 * 22% * 15/365 = 66.90
2,500 * 22% * 16/365 = 24.11
66.90 + 24.11 = 90.21
138.27 - 90.21 = 48.06
She would pay 48.06 more with the previous balance method than with the adjusted balance method.
Solution:
Adjusted Balance method
Amount in Lorenzo credit card in the beginning of month= $ 4100
Payment made = $ 2300
Amount in Lorenzo credit card after 15 days = $ 4100 -$ 2300= $ 1800
APR= 24 %
Monthly APR = [tex]\frac{24\times 31}{365}=2.038[/tex]%
2.03% of 1800=$ 36.54
Previous Balance method:
Amount possessed at the beginning of the month= $ 4100
APR= 24 %
Monthly APR = [tex]\frac{24\times 31}{365}=2.038[/tex]%
2.038% of 4100=$ 83.23
The interest that Lorenzo would pay for the billing cycle with the previous balance method than with the adjusted balance method

When converting from binary to hexadecimal, 4 binary digits is equivalent to _____ hexadecimal digit(s)?
Answers
Final answer:
In conversions from binary to hexadecimal, 4 binary digits are equivalent to 1 hexadecimal digit due to the fact that the base-16 system of hexadecimal can represent any combination of 4 binary digits (base-2 system).
Explanation:
When converting from binary to hexadecimal, 4 binary digits are equivalent to 1 hexadecimal digit. This is because binary is a base-2 system and hexadecimal is a base-16 system. Each hexadecimal digit can represent 4 binary digits since 24 = 16. Here's a quick conversion table for single binary digits to hexadecimal:
0000 = 0
0001 = 1
0010 = 2
0011 = 3
0100 = 4
0101 = 5
0110 = 6
0111 = 7
1000 = 8
1001 = 9
1010 = A
1011 = B
1100 = C
1101 = D
1110 = E
1111 = F
Therefore, when performing this conversion, group the binary numbers into sets of 4 digits from right to left and then convert each group to the corresponding hexadecimal digit.
