Which angles are consecutive interior angles?

Lets turn 3.85% into a decimal first. Multiply 0.0385 with 410,000 which gives you 15785. Add that to 410,000 which gives you 425785. Multiply 3.85 by 425785. Repeat that process 5 times until you get the amount of interest earned after 5 years.

Answer:

No (not a proportional relationship)

Step-by-step explanation:

The cost of fountain drinks at Hot Dog Hut:

[tex]\begin{array}{|c|c|}\cline{1-2} \sf Volume & \sf Cost \\\sf \sf (fluid\;ounces) & \sf(\$) \\\cline{1-2} \vphantom{\dfrac12}16& 1.49\\\cline{1-2} \vphantom{\dfrac12}20&1.59 \\\cline{1-2} \vphantom{\dfrac12}30& 1.89\\\cline{1-2} \end{array}[/tex]

A proportional relationship is one in which two quantities vary directly with each other.

Calculate the rate of change of the ordered pairs.

Rate of change between (30, 1.89) and (20, 1.59):

[tex]\implies \dfrac{1.89-1.59}{30-20}=\dfrac{0.3}{10}=0.03[/tex]

Rate of change between (20, 1.59) and (16, 1.49):

[tex]\implies \dfrac{1.59-1.49}{20-16}=\dfrac{0.1}{4}=0.025[/tex]

As the rates of change are different (not constant), the relationship is not proportional.

Note:  The graph of a proportional linear relationship is a line that passes through the origin (0, 0).

The value of (a) x is 3 and (b) the length RT is= 14 units

The corrected question form a triangle. and the lengths of the triangle are give as

rs=9x-13

st=10x-3

rt=4x+2

Using the supporting values to find the lengths we have

s=t and rs=rt

This implies that

rs=9x-13=rt=4x+2

Equating the two equations we have

9x-13=4x+2

Collecting like terms

9x-4x=2+13

⇒5x=15

Making x the subject of the formula

x=15/5=3 units

In the same way, rs=9x-13=9(3)-13

=27-13=14 units

Also, st=10x-3

Substitute x=3 in the equation we have

10(3)-3

=30-3

=27

Recall that rt=4x+2

by substitution we have

4(3)+2

=12+2

Answer:

256 miles

Step-by-step explanation:

1 cm = 8 miles

32 cm = x miles

32 * 8 = 256 miles

Therefore, the value of the scalar k for which the two vectors are orthogonal is k =1/5.

In physics and mathematics, the term "vector" is used to refer, informally, to certain quantities that cannot be described by a single number or to certain constituents of vector spaces.

Here,

When the dot product of two vectors is zero, those two vectors are said to be orthogonal.

Dot product:

Let's assume we have the two vectors a and b.

a = (1,2) (1,2)

b = (2,3) (2,3)

Their dot item is:

a.b = (1,2). (1,2).

(2,3) = 1*2 + 2*3 = 8

Regarding this issue:

u = (2,3) (2,3)

(k + 1, k - 1) = v

So

u.v = (2,3). (2,3).

(k + 1, k - 1) = 2k + 1, 3k - 1, or 2k + 2, 3k - 3, or 5k - 1

The vectors must be orthogonal for the dot product to equal 0.

So:

=> 5k -1 =0

=> 5k =1

=> k =1/5

Therefore , the value of the scalar k for which the two vectors are orthogonal is k =1/5.

The campers will be 40 miles from their car after 12 hours.

Given :

A group of hikers park their car at a trail head and hike into the forest to a campsite. The next morning, they head out on a hike from their campsite walking at a steady rate. The graph shows their distance in miles, d, from the car on the day of their hike after h hours .

We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:

slope m = y2 - y1 / x2 - x1

Choosing the points (0,4) and (2,10), we get:

m = 4 - 10 / 0 - 2

= -6 / -2

= 6 / 2

= 3

We can substitute the point (0,4) and the slope into y = mx + b and solve for "b":

4 = 3 * 0 + b

b = 4

Then, the equation of this line is:

y = 3x + 4

Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:

d = 3h + 4

if h = 12

d = 3 * 12 + 4

= 36 + 4

Answer:

[tex]r=\dfrac{5\sqrt{2}}{4}}\:i\:,\quad \;\;r=-\dfrac{5\sqrt{2}}{4}}\:i[/tex]

Step-by-step explanation:

To solve the given equation, rearrange the equation to isolate r.

Given equation:

[tex]0=-16r^2-50[/tex]

Add 16r² to both sides of the equation:

[tex]0+16r^2=-16r^2-50+16r^2[/tex]

     [tex]16r^2=-50[/tex]

Divide both sides of the equation by 16:

[tex]\dfrac{16r^2}{16}=\dfrac{-50}{16}[/tex]

   [tex]r^2=-\dfrac{25}{8}[/tex]

[tex]\textsf{For\;\:}x^2=f\left(a\right)\textsf{\:the\:solutions\:are\:\:}x=\pm\sqrt{f\left(a\right)}[/tex]

[tex]r=\pm\sqrt{-\dfrac{25}{8}}[/tex]

[tex]\textsf{Apply\;the\:radical\:rule:}\;\:\sqrt{-a}=\sqrt{a}\sqrt{-1}[/tex]

[tex]r=\pm\sqrt{\dfrac{25}{8}}\sqrt{ -1}[/tex]

Simplify the numerator and denominator of the fraction:

Infinite number of integers that satisfy the inequality |x|<4.

Step-by-step explanation:

The absolute value of a number indicates its distance from 0 on the number line. Therefore, the inequality |x|<4 indicates that x is less than 4 units away from 0 on the number line. Because there are an infinite number of integers on the number line, there are an infinite number of integers that satisfy the inequality |x|<4.

The number of possible outcomes is divided by the total number of possible outcomes to determine probability. Odds are not the same as probability. Odds are calculated by dividing the chance of a given event by the probability that it won't.

The likelihood of success is a measure of probability. the number of potential outcomes. For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one way to acquire a head and there are a total of 2 possible outcomes (a head or tail). We express P(heads) = 12.

There is sufficient warrant to rejection of the claim that 64% of the readers of the publisher own a personal computer at a = 0.01 level of significance.

What is the null hypothesis?

Two alternatives being the same is the null hypothesis. The underlying assumption is that the observed difference is just the result of chance. It is feasible to determine the probability that the null hypothesis is correct using statistical testing.

Here, we have

P = population proportion of readers, who own personal computers.

The claim of the publisher: 64% of their readers own a personal computer.

Since the claim indicates a specific value about P, it should be treated as the null hypothesis and thus the required null and alternative hypothesis would be -

H₀ : p = 0.64

H₁  : p ≠ 0.64

Now, at a = 0.01, it is decided to reject the null hypothesis.

For the time being, our first task is to determine the sensitivity, which is the derivative of our discovery. The quotient rule, whose derivative we shall be utilizing, says that the derivative of F org equals G f prime minus f g prime all over g squared.

The bottom function is one plus four times the top function's derivative, or 40.4 times. 40 has a derivative of zero.

When a light source is x cm away from a light probe, the light's intensity is measured as y microwatts per square cm. The outcomes are displayed as ordered pairs( x , y).

So we just need to multiply 24 x240.4.

Using the power rule, we can reduce the 0.4 point to 9.6 x to the minus 0.6.

We subtract one from the initial exponents minus the top function 40 + 24 x to the point for times the bottom function's derivative 10 So we have the derivative of four additional 40.4 by the power rule,

50a= 1 cal

150 licks per minute, 2 ants per lick--- 2*150 = 300 ants per minute

6*50a= 1 cal*6

-- 300a = 6cal

The anteater can get a avg of 6 calories per minute.

6*60 = 360

We can make a equation:

x =calories

360x = 1800

360/360x = 1800/360

x = 5

It would take the anteater a total of 5 hours to withdraw 1800 calories from ants. This is 300*60*5 ants!

However, the given information states that the hyperbola passes through the point (2,2). This can be achieved by shifting the hyperbola to the right and up by 2 units, resulting in the equation (x-2)² + (y-2)² = 4.

The asymptotes of a hyperbola are the lines that the hyperbola approaches but never touches as it extends to infinity. The asymptotes of a hyperbola centered at the origin are the x-axis and y-axis. Since this hyperbola has been shifted to the right and up by 2 units, the asymptotes are the x-axis and y-axis shifted by 2 units in the same direction.

In mathematics, a continuous function is a function such that a continuous variation (that is a change without jump) of the argument induces a continuous variation of the value of the function. This means that there are no abrupt changes in value, known as discontinuities. More precisely, a function is continuous if arbitrarily small changes in its value can be assured by restricting to sufficiently small changes of its argument. A discontinuous function is a function that is not continuous. Up until the 19th century, mathematicians largely relied on intuitive notions of continuity, and considered only continuous functions. The epsilon–delta definition of a limit was introduced to formalize the definition of continuity.
