which of the following graphs is increasing only when x <0?

From the given triangle JKL, measure angle K is 65 degrees.

The length of the sides distinguishes triangles of the scalene, isosceles, and equilateral kinds. If the lengths of the three sides are all different, the triangle is a scalene triangle. A triangle that has equal lengths on each of its three sides is said to be isosceles.

The measure of angle j in the triangle JKL is 30 degrees less than the measure of angle K, while the measure of angle L is 80 degrees. measure the angle K.

Suppose angle K = x, at which point angle J = x-30 degrees, and angle L = 80 degrees.

The total of a triangle's three angles is 180 degrees, or K+L+J = 180.

The angles of the triangle are

since x+80+x-30

= 180 + 2x

= 180-80+30

= 130 and

x= 130/2 = 65 degrees.

The given k-value of 0.1459, we can calculate the amount of the sample left after any given amount of time.

Amount is a numerical quantity that is used to measure the size or magnitude of something. It is typically expressed in terms of a unit of measure such as a dollar, pound, or other currency.

The given k-value of 0.1459 corresponds to the rate of decay of the 9 gram sample of the substance over time. The equation for determining the amount of the sample left after a certain amount of time (t) is: N = -kt, where N is the amount of the sample left after the given amount of time, k is a positive constant that depends on the substance itself and on the units used to measure time, and t is the amount of time in days.

N = N0 e^(-kt)

for half life N/N0 = 1/2 and k = 0.1459

1/2 = e^(-0.1459t)

=> -0.1459 t = ln(0.5)

t = - ln(0.5) /0.1459

= 4.8 days       

Therefore, with the given k-value of 0.1459, we can calculate the amount of the sample left after any given amount of time.

The finding that the number of cigarettes smoked being -10 to predict a birth weight of 125 ounces is unrealistic could be due to the fact that the model doesn't take into account other factors that could impact the weight of the child.

The simplified expression is equal to 13/24 - 3/8b.

It represents a value that can change, depending on the values of the variables.

For example, "2x + 3" is an algebraic expression. The variable x can take on any value, and the expression represents a value that is the result of adding 2 times x to 3. When x is equal to 5, the expression equals 2 * 5 + 3 = 13.

Algebraic expressions can be combined using the operations of addition, subtraction, multiplication, and division to form more complex expressions. They can also be simplified by combining like terms or using the distributive property.

Algebraic expressions are an important tool in mathematics, and are used in many areas including science, engineering, and economics. They can be used to model and understand complex systems, and to make predictions and analyze data.

The expression -1/4 + 1/12 - 1/8b + 13/24 can be simplified by finding the common denominators and adding the numerators:

-1/4 + 1/12 - 1/8b + 13/24 = (3 * -1/12) + (3 * 1/12) - (3 * 1/8b) + (3 * 13/72) = 3 * (-1/12 + 1/12 - 1/8b + 13/72) = 3 * (13/72 - 1/8b) = 13/24 - 3/8b.

Ma = 3x - 15, since mbdc = 3(x - 5) and m arc bc = x 25. Therefore, ma = 3x - 15, which is the product of 3 times (x-5).

The probability that the proportion in a random sample is 0.99997.

The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

For this case we have a random sample of 2500 people, this value represent n.

We know that in the sample selected the number of people who say that prefer shop online rather than in a store are 1575.

For this case we can calculate the sample proportion with this formula:

h(p) = x/n

       = 1350/ 2500

       = 0.54

Now, [tex]\mu_p =[/tex] 0.54

and, [tex]\sigma_p[/tex] = √0.54 (1- 0.54)/2500

            = 0.00996

and, we want to calculate the following probability:

P(p>0.50)

= 1- P(p< 0.50)

= 1 - P(z < (0.5 - 0.54)/ 0.00996)

= 1 - P(z< -4.016)

Answer:

Step-by-step explanation:

area of a cylinder = top circle + bottom circle + lateral

r=4 h=5

lateral = perimeter of the circle * height = 2π*4 * 5 =40π

area of a circle = πr² = 16π

top & bottom =32π

total = 40π+32π =72π = 226.08

The surface area of a cylinder exists 72π square units.

A cylinder's surface area is equal to two times the sum of its side and base areas.

Let the equation be

Surface area = 2(base area) + (side area)

The Base area of the equation be

Base area = πr²

When r = 4,

substitute the values in the above equation, we get

Base area = π(4)²

simplifying the equation, we get

Base area = 16 π

side area = 2πrh

side area = 2π × 4 × 5

side area = 40π

The Surface area of the equation be

Surface area = 2(base area) + (side area)

substitute the values in the above equation, we get

surface area = 2 × (16 π) + 40π

simplifying the equation, we get

surface area = 32π + 40π

surface area = 72π

Therefore, the surface area exists 72π square units.

Explanation:

3/4 = 0.75

1/2 = 0.50

The three given angles in decimal form are:

If these angles add to 180 degrees, then a triangle can be formed.

31.75+53.50+94.75

85.25+94.75

So, 31.75+53.50+94.75 = 180 is definitely the case.

Therefore, a triangle can be formed.

You'll type the mixed number [tex]31\frac{3}{4}[/tex] into the box which was that first angle mentioned.

In an isosceles triangle, if Angle DBC has a measure of 110 degrees and angle BDA has a measure of 22 degrees, then the measure of angle BAC is 48 degrees.

A triangle with two equivalent sides and angles with equal measures on opposing sides is said to be isosceles.

Triangle BAC's angles should be labelled as follows:

Angle BAC = x

Angle ABC = y

Angle BCA = z

Because a triangle's angles sum up to 180 degrees,

x + y + z = 180

As ACD and BCD are isosceles triangles,

angle DBC = angle DCB = 110 degrees

Because BDA and DBC are a pair of linear angles,

angle BDA + angle DBC = 180 degrees

Using values for angles DBC and BDA and substituting them,

22 + 110 = 180

By finding y,

y = 180 - 22 - 110

When the value of y is substituted in the equation x + y + z = 180,

x + (180 - 22 - 110) + z = 180

Solving for x,

x = 180 - (180 - 22 - 110) - z

Substituting the value of z = 180 - (22 + 110),

x = 180 - (180 - 22 - 110) - (180 - 22 - 110)

By critically observing the graph which represents the function (see attachment), we can logically deduce that the vertical intercept (y-intercept) is equal to the ordered pair (0, 7).

Additionally, the maximum point of any graph is the point where the graph is at the highest point, which is equal to the ordered pair (4, 16) while the minimum point of any graph is the point where the graph is at the lowest point, which is equal to the ordered pair (1.5, 2).
