[tex]2d^3-7d^2-103d+36[/tex]

Step-by-step explanation:

The given expressions are (d-9) and [tex]2d^2+11d-4[/tex].

Their product is given by:

[tex](d-9)(2d^2+11d-4)[/tex]

We expand using the distributive property to obtain;

[tex]d(2d^2+11d-4)-9(2d^2+11d-4)[/tex]

[tex]2d^3+11d^2-4d-18d^2-99d+36[/tex]

We group similar terms to get;

[tex]2d^3+11d^2-18d^2-4d-99d+36[/tex]

We combine the similar terms to get:

[tex]2d^3-7d^2-103d+36[/tex]

Final answer:

To solve the equation 4x = -4r + 2d for x, isolate x by performing the same mathematical operations on both sides of the equation.

Explanation:

To solve the equation 4x = -4r + 2d for x, we need to isolate x on one side of the equation. We can do this by performing the same mathematical operations on both sides of the equation. Let's start by moving the terms containing r and d to the other side:

4x + 4r - 2d = 0

Next, we can factor out the common factor of 4:

4(x + r - 0.5d) = 0

Finally, we divide both sides of the equation by 4 to solve for x:

x + r - 0.5d = 0

The solution for x is x = -r + 0.5d.

The area of a circle is calculated using the formula,

[tex]Area = \pi \: {r}^{2} [/tex]

The given circle has radius, r=8 units.

We substitute the radius into the formula to obtain:

[tex]Area = \pi \times {8}^{2} [/tex]

The exact area is 64π square units.

When we substitute π=3.14, we get,

Area=201.06 units square.

The measure of arc CD is 88.8°

In circle geometry , there are certain theorems that guides the solving of problem involving circles.

Some of the theorems are ;

angle at the center is twice angle at the circumference.

The measure of arc is the measure of angle substended at the centre.

Using trigonometric ratio to get the angle at the center.

sinX = 6.35/9.06

sinX = 0.70

X = 44.4°

angle at the centre = 2 × 44.4

= 88.8°

Therefore, arc CD is 88.8°

Answer:

l = 65 – 15d; discrete

Step-by-step explanation:

15 is the centimeters he cuts off every day, you have to multiply that by D that´s the nomber of days, in order to calculate how much baguette does he have left.

If 4 days have passed, the anser would be 5 centimeters:

I=65- 15(4)= 65-60= 5

Answer:

[tex]l=65-15d[/tex]; discrete.

Step-by-step explanation:

Let d represent number of days.

We have been given that for lunch every afternoon, Diep cuts 15 centimeters of bread for his  sandwich. The length of loaf cut in d days would be [tex]15d[/tex].

Diep bought a baguette loaf of bread 65 centimeters long. The length of loaf of bread after d days would be initial length minus amount of loaf cut in d days that is:

[tex]65-15d[/tex]

Since [tex]l[/tex] represents length of bread, so our equation would be: [tex]l=65-15d[/tex]

Therefore, the expression [tex]l=65-15d[/tex] represents the given scenario.

The variable d represents number of days and days cannot be fractional. We can take only whole number of days, therefore, the graph of the equation would be discrete.

Answer:

of the number is X, 16 = 1 + (2/10)×X - 8

Answer:

16 = [tex]\frac{6x}{5}[/tex] - 8

Step-by-step explanation:

Topic: One Unkown equation, mixed numbers

first we have to establish our variables, we only have one so we call

x = "a number"

and we start building our one unknown equation part by part by reading

"Sixteen is the same" means in math that "x ="

"one and two tenths"  1 [tex]^{2/10}[/tex]

this means we have (remember how to sum fractions?)

1 + 2 / 10 = 10/10 + 2/10 = 12/10 = 6/5

so " one and two tenths times a number added to negative 8" become [tex]\frac{6x}{5}[/tex] + (-8)

so we have our equation

16 = [tex]\frac{6x}{5}[/tex]  + (-8) or 16 = [tex]\frac{6x}{5}[/tex]  - 8

The measure of each interior angle of a regular polygon is given by

[tex] \theta = \frac{(n - 2) \times 180}{n} [/tex]

where n refers to the number of sides of the polygon.

From the question we have n=5 in this case.

We substitute to obtain;

[tex]\theta = \frac{(5 - 2) \times 180}{5} [/tex]

[tex]\theta = \frac{3\times 36}{1} [/tex]

This simplifies to:

[tex]\theta = 108 \degree[/tex]

Hence each interior angles of a regular polygon with 5 - sides is 108°

The square root of f(x) is ±(x + 12) and the square root of g(x) is not defined.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable).

f(x) = x^2 + 24x + 144

f(x) = x^2 + 2(12)x + 12^2

f(x) = (x + 12)^2

Square root of f(x) is ±(x + 12)

g(x) = x^3 - 216

g(x) = (x - 6)(x^2 + 6x + 36)

Here, (x^2 + 6x + 36) does not have real roots hence it is not possible to find the square root of g(x).

To find the missing value, divide two consecutive y-values to determine the constant factor. Multiply the last given value by the factor to obtain the missing value.

To find the missing value for the exponential function represented by the given table, we need to observe the pattern of the function.

The given pattern is:

x   -2    -1       0          1           2

y  29  20.3  14.21   6.9629

In this case, we can see that each value of y is obtained by multiplying the previous value by a constant factor.

To determine this factor, we can divide any two consecutive y-values.

For example, dividing 14.21 by 20.3 gives us approximately 0.6988.

So, the missing value can be found by multiplying the last given y-value (6.9629) by this factor.

Hence, the missing value is approximately 4.8616.

The area of a circle when you know the radius is found using the formula Area = PI x r^2

The small circle has a radius of  7 inches.

The area of the small circle is 3.14 x 7^2 = 3.14 x 49 = 153.86 square inches.

Using the circumference of a circle use the formula Area = C^2 / 4*PI

Area of larger circle = 113.097^2 / 4 *3.14 = 12790.93141 / 12.56 = 1018.39 square inches.

Now to find the blue area subtract the area of the smaller circle from the larger one:

1018.39 - 153.86 = 864.53 square inches.

Step-by-step explanation:

We are to find out what percentage of 700 is 14.

Assuming [tex] x [/tex] to be the percent of 700 which is 14, we can write it as:

[tex] \frac { x } { 100 } \times 700 = 14 [/tex]

[tex] \frac { x } {100} = \frac {14} {700} [/tex]

[tex] \frac { x } { 1 0 0 } = 0.02 [/tex]

[tex]x=0.02 \times 100[/tex]

[tex]x=2[/tex]

Therefore, 14 is 2% of 700.

I think B. 10 2/3

Step-by-step explanation:

I haven't learned this yet but out of experience i think this is how you solve it. Find out the ratio of 18 to 8 by dividing 18/8 to get 2.25. then multiply this by 24 to get 10.66 repeated which equals to 10 and 2/3.

14 + 7 + 10 = 31 marbles total

7/31 = 0.23 or 23%

The probability of drawing a black marble from a bag containing 14 gray, 7 black, and 10 white marbles is 7/31, which, as a decimal rounded to the nearest hundredth, is 0.23.

The theoretical probability of drawing a black marble from a bag containing 14 gray, 7 black, and 10 white marbles can be calculated by dividing the number of black marbles by the total number of marbles in the bag.

To find the total number of marbles, we add up the counts for each color: 14 gray + 7 black + 10 white = 31 marbles in total.

Next, we calculate the probability by taking the number of black marbles and dividing it by the total number of marbles: Probability = (Number of black marbles) / (Total number of marbles) = 7 / 31.

Converting that probability into a decimal gives us approximately 0.2258. However, rounding this to the nearest hundredth, as asked in the question, gives us 0.23. So, the probability of drawing a black marble is 0.23.

To show Lin's elevation at 3:00 p.m on a graph, mark a point below her starting altitude at 2:00 p.m, given that she was climbing downwards. The exact placement will depend on her descent rate, for which we have no data.

The question refers to Lin climbing downwards in the period from 2:00 p.m. to 3:00 p.m. In order to plot Lin's movement on a graph, we need to define the vertical axis as her altitude and the horizontal axis as time. Since Lin was moving downward, her altitude at 3:00 p.m. should be less than her altitude at 2:00 p.m.

For example, if she started at an altitude of 4,000 meters at 2:00 p.m., when adding a point to the graph at 3:00 p.m., it should be below the 4,000-meter altitude point, since Lin was descending. The exact point will depend on the speed of her descent, which we don't have information on, but it would be somewhere below the starting point.

It's similar to the thrown rock example where the rock rises and then falls. Lin, like the rock, started at a higher point (instead of airborne, she was high on a cliff or a hill), but then moved downwards, decreasing her altitude over time.

The point is placed at -50 feet to represent a possible elevation halfway between 0 feet and -100 feet. However, it is important to note that her actual elevation could be anywhere within this range.

Assuming Lin started climbing from an elevation of 0 feet at 2:00 p.m., she could have reached a negative elevation at 3:00 p.m. This is because the graph shows that she was descending at a constant rate.

To determine her possible elevation, we need to consider the following:

The slope of the graph represents the rate of change in elevation. A negative slope indicates that Lin is descending.

The y-intercept of the graph represents Lin's elevation at 2:00 p.m. Since she started at 0 feet, the y-intercept is 0.

The time interval from 2:00 p.m. to 3:00 p.m. is one hour.

Using this information, we can determine that Lin's elevation at 3:00 p.m. could be anywhere from 0 feet to -100 feet. This is because the slope indicates that she is descending at a rate of -100 feet per hour.
