Japan sells cars to the United States. Japan considers the cars as Japanese _____. imports
exports

Answers

Answer:

Japan considers the cars as Japanese exports.

Step-by-step explanation:

We are given the statement that,

'Japan sells cars to the United States'.

Now, we know,

Imports - Are referred to the goods brought into the country across the national border, from an external source.

Exports - Are referred to the trade of goods where the goods are sold to another country.

Since, according to the statement,

Japan sells the car to the US. This means that the goods are going out of Japanese border.

Thus, Japan considers the cars as Japanese exports.

export because it is leaving their country

There are 10 sports balls in the equipment closet. Three are kickballs . Write the portion of the balls that are kickballs as a fraction, as a decimal, and in word form

Answers

Answer:

Proportion of kickball =

$p =(x)/(n) = (3)/(10)\n\np=0.3$

Step-by-step explanation:

We are given the following in the question:

Total number of ball, n = 10

Number of kickball,x = 3

Proportion of balls in fraction =

$p =(x)/(n) = (3)/(10)$

Proportion of balls in decimals =

$p =(x)/(n) = (3)/(10)\n\np=0.3$

Proportion in words =

3 out of 10 balls are kick balls that is 30% of the balls are kick balls.

True or False. A function's graph may include solutions that do not appear in its table of values.

Answers

Yes it is true that a functions graph always include solutions that do not appear in its table of values.

What is a function?

An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is a graph of function.

Yes a functions graph always include solutions that do not appear in its table of values. The graph of the function represent all the points that satisfy the function on both sides. The table of values is made just to represent only some of the solutions from the total solutions.

Therefore, yes it is true that a functions graph always include solutions that do not appear in its table of values.

A country's population in 1993 was 72 million. In 1996 it was 76 million. Estimate the population in 2003 using exponential growth.

Answers

We use the formula for exponential growth:
P = Po exp(kt)
Using the population data from 1993 to 1996, we can solve for the growth rate k
76 = 72 exp(k(3))
76/72 = exp(3k)
ln (76/72) = 3k
k = ln(76/72) / 3 = 0.0180

In 10 years (2003), the population will be:
P = Po exp(0.0180t)
P = 72 exp(0.0180(10))
P = 86.22 million

Hagrid is correct but its asking to the nearest million so it's 86 mill so just type in 86 then press enter

What is the length of AC ? Round to the nearest tenth.10.5 m
12.3 m
18.3 m
21.4 m

Answers

The length of AC is equal to 10.5m

Data;

AC = ?
BC = 15m
Angle = 55 degrees

Trigonometric Ratio

To solve this problem, we have to apply trigonometric ratioSOHCAHTOA here;

Since we have the value of opposite side, angle and we are looking for the adjacent, we can use tangent of the angle to find AC
$tan\theta = (opposite)/(adjacent)$

Let's substitute the values and solve for AC

$tan 55 = (15)/(AC) \nAC = (`15)/(tan55) \nAC = 10.5m$

From the calculations above, the length of AC is equal to 10.5m

In this right triangle, side AC is adjacent to the reference angle we were given. That's our unknown. The other side is the side opposite the reference angle, so we need a trig ratio that relates the side adjacent to the side opposite which is tangent. Setting up our ratio we have this: $tan(55)= (15)/(x)$ and $x= (15)/(tan(55))$ . Do that on your calculator to find that side AC (x) = 10.5, first choice above.
