Answer:

The depreciation each year is option B. $1500.00

Step-by-step explanation:

Initial value of car = $9600

Salvage value = $600

Salvage value is the final value of product after all the depreciation have been applied on the product.

So, total depreciation on the car = [tex]\$9600 - \$600 \Rightarrow \$9000[/tex]

Also, it is given that the depreciation occurs at a straight line method i.e. same depreciation occurs every year.

Depreciation in 6 years = $9000

Depreciation in 1 year =

[tex]\dfrac{\$9000}{6} \Rightarrow \$1500[/tex]

Hence, option B. $1500 is the correct answer for the depreciation every year.

Answer:

[tex]Sin156[/tex]

Step-by-step explanation:

Given

[tex]Sin24[/tex]

Required

Find equivalent between 0 to 180;

Let 24 be represented by [tex]\theta[/tex]

So, [tex]\theta = 24[/tex]

From Trigonometry ratios;

[tex]Sin\theta = Sin(180 - \theta)[/tex] where [tex]0\leq \theta \leq 180[/tex]

Recall that [tex]\theta = 24[/tex]

So, we have to substitute 24 for [tex]\theta[/tex] in the above expression.

This gives

[tex]Sin24= Sin(180 - 24)[/tex]

Subtract 24 from 180

[tex]Sin24= Sin156[/tex]

Hence, the equivalent of [tex]Sin24[/tex] is [tex]Sin156[/tex]

Answer: Forty-seven percent is the statistic and 31% is the parameter.

Step-by-step explanation:

Here is the complete question:

A study of parents of kindergarteners included 349 parents who were

chosen at random. Of these parents, 47% said they sent their children to pre-kindergarten. School records show that only 31% of parents of kindergarteners sent their children to pre-kindergarten. Identify the statistic and the parameter.

Three hundred forty-nine is the parameter and 47% is the statistic.

Three hundred forty-nine is the statistic and 47% is the parameter.

Three hundred forty-nine is the parameter and 31% is the statistic.

Forty-seven percent is the parameter and 31% is the statistic.

Forty-seven percent is the statistic and 31% is the parameter.

A parameter is a value which tells one about something about a population. A parameter is the opposite of a statistic. A statistic tells you something about a small part of the population.

Sample size (n) = 349

From the given sample, we are told that 47% parents sent their students to pre-kindergarten and also that the school record shows that 31% parents sent their students to pre-kindergarten which is, p =0.31

So, 47% is the statistic and 31% is the parameter.

Answer:

Forty-seven percent is the statistic and 31% is the parameter.

Answer:

∠B` = 109.73°, ∠B = 70.27°

Step-by-step explanation:

∠B + ∠B` = 180°

The Sine Law:

10 / sin B` = 9.2 / sin 60°

10 / sin B` = 9.2 / √3/2

sin B` = 0.94133

B` = sin^(-1) 0.94133

∠B` = 109.73°, ∠B = 70.27°

Answer:

27 laps

Step-by-step explanation:

So first step is to work out how many times 11 fits into 60

Then you would times that by the number of laps which is 5

[tex]5.454545455 \times 5 = 27.27.....[/tex]

So it is 27 laps as .27 of a lap is not a complete lap

These all thave the same quotient of 3.2

Step-by-step explanation:

The fractions which are given and and which are also required are called equivalent fraction. In this, the denominator and numerator of both fractions is different, but when you divide the numerator and denominator to get a value, the values of both the fractions are found same.

To find 2 mixed number or fraction with a quotient 3.2.

We can write 3.2 in the fractional form:

[tex]3.2 = \frac{32}{10}[/tex]

Now multiply both the numerator and denominator with 2, we get

[tex]\frac{2\cdot32}{2\cdot10}= \frac{64}{20}[/tex]

which also has the quotient 3.2

Similarly, multiply both numerator and denominator of 32/10 by 3, we get

[tex]\frac{3\cdot32}{3\cdot10}=\frac{96}{10}[/tex]

whici also has the quotient of 3.2

Similarly we can go on to find as many values as we want with the same quotient.

Answer:

58 degrees

Step-by-step explanation:

In a rectangle, the two diagonals form four isosceles triangles. This means triangle EBC is isosceles. In an isosceles triangle, the two base angles are the same. So, angles EBC and BCE are both 61. Now, in a triangle, the three angles add up to 180. So, 61+61=122, and to find angle CEB you need to subtract 180-122. 180-122=58 degrees.

Answer:

58°

Step-by-step explanation:

to find m∠CEB

triangle CEB is formed by the two parts of rectangle diagonals (and BC), and as we know, diagonals bisect each other, thus EB is congruent to EC, and it is an isosceles triangle

We also know that angles opposite congruent sides are congruent, thus,

angles EBC and ECB are congruent

thus angle ECB= 61°

We know that the inner angle measures of a triangle according to Angle Sum Theorem add up to 180°

Thus,m angle EBC + m angle ECB + m angle CEB= 180

Now we know that both EBC and ECB are angles with the measure of 61 °, so lets put the measures in instead of angles into the equation

61+61+m angle CEB=180

122 + m angle CEB =180

         m angle CEB=180-122

        m angle CEB=58°

Answer:

y = -3x + 12

Step-by-step explanation:

Very similar to the other question i answered, by here's a step by step anyway in case you find it helpful : )

There are lots of different methods to do these types of questions, but this is the way i like to do it.

Coordinate (x1, y1) : (1, 9) and Gradient (m): -3

Start with this generic equation:

y- y1 = m(x-x1)

Substitute in the values they have given you:

y - (9) = -3(x-1)

This becomes:

y -9 = -3x +3

Keep solving by moving the 10 over to the other side:

y = -3x + 3 +9

y = -3x + 12

An easy way to double check:

1) the coefficient of x is the slope. We got -3x, and the slope is -3, so that's correct.

2) Substitute x=1 into the equation, and we get 9, which is the exact coordinate that they gave us. This is also right.

Answer:

13

Step-by-step explanation:

f(10)=10/2+8

f(10)=5+8

f(10)=13

Hey there!

Answer:

f(x) = 13 when x = 10.

Step-by-step explanation:

To find f(x) when x = 10, simply substitute '10' for 'x'.

[tex]f(x) = \frac{x}{2} + 8[/tex]

Subsitute in '10' for 'x':

[tex]f(10) = \frac{10}{2} + 8[/tex]

Simplify:

[tex]f(10) = 5 + 8[/tex]

[tex]f(10) = 13[/tex]

Therefore, f(x) = 13 when x = 10.

ANSWER: The answer is C

Agree with Elena, because 9x - 2x + 4x is equivalent to 11x, after the subtraction only applies to 2x.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Noah says that 9x - 2x + 4x is equivalent to 3x, because the subtraction sign tells us to subtract everything that comes from after 9x.

And, Elena says that 9x - 2x + 4x is equivalent to 11x, because the subtraction only applies to 2x.

Now,

Since, We know that;

⇒ 9x - 2x + 4x

⇒ 7x + 4x

⇒ 11x

Thus, Elena is correct as;

⇒ Elena says that 9x - 2x + 4x is equivalent to 11x, because the subtraction only applies to 2x.

Answer:

a) 1.50 m/s²

b) 675m

c) 11.25 m/s

Step-by-step explanation:

1. a) Acceleration can be found from the gradient of a speed-time graph, which is the graph we have here.

Notice that the graph from t=0 to t=10 has the same gradient thoughout (since it is a straight line). Hence, the acceleration when t=4 is the same as the acceleration from t=0 to t=10.

To find the gradient of the graph from t=0 to t=10, use the gradient formula below:

gradient=[tex] \frac{y1 - y2}{x1 - x2} [/tex]

The coordinates of the point at t=0 is (0,0) and the point at t=10 is (10,15).

Thus, gradient

[tex] = \frac{15 - 0}{10 - 0} \\ = \frac{15}{10} \\ = 1.5[/tex]

Therefore the acceleration when t=4 is 1.50 m/s².

*Acceleration is the rate of change of velocity (or speed).

b) Distance travelled can be found by calculating the area under a speed-time graph.

The area under the graph is the orange trapezium that the question has shaded for you already.

Formula for area of trapezium= ½(a+b)(height)

a+b is the total length of the two parallel horizontal lines of the trapezium.

Let the top line be a and the bottom line be b.

length of a= distance between (10,15) and (40,15)

Length of a

= 40 -10

= 30 units

Length of b

= 60 -0

= 60 units

height of trapezium= 15 units

Area of trapezium

= ½(30 +60)(15)

= 675 units²

Thus, the distance travelled is 675m.

c) Avg speed= total distance ÷ total time

From part b, we know that the total distance travelled is 675m. The total time is 60s since the graph is from t=0 to t=60.

Hence, average speed

= 675 ÷60

= 11.25 m/s
