Chris plans to buy a car that depreciates in value at a rate of 10% per year. If the car initially costs $32,000. How much will the car be worth after 5 years?

Answer:

8m ×3.5m

Step-by-step explanation:

Area of rectangle= length ×width

Let the length and width of the rectangle be L and W meters respectively.

Area of rectangle= LW

LW= 28 -----(1)

L= 2W +1 -----(2)

Subst. (2) into (1):

(2W +1)(W)= 28

Expand:

2W² +W= 28

-28 on both sides:

2W² +W -28= 0

Factorise:

(W +4)(2W -7)= 0

W +4=0 or 2W -7=0

W= -4 (reject) or W= 3.5

Substitute W= 3.5 into (2):

L= 2(3.5) +1

L= 7 +1

L= 8

∴ The dimensions of the rectangle is 8m ×3.5m.

Answer:

No

Step-by-step explanation:

Due to the absence of the squared coefficient, we can automatically strike this as not a quadratic.

And, judging by the terms of the function, this is a trinomial.

Answer:

false and 8 hours and 55 min

Step-by-step explanation:

Answer:

false. 8.9 in the scenario would be 9 hours and 30 minutes

Step-by-step explanation:

using decimals is not an accurate way to measure time.

if it was used, 8.9 would be 8 hours and 90 minutes. However, there are only 60 minutes in an hour, so 8.9 would translate to 9 hours and 30 minutes.

Answer:

0.75 could be a 25% discount. 1.06 could be a sales tax.

Step-by-step explanation:

If  p  is the original price, then  1.06p  could be the amount after a 6% tax is include.  Then multiplying by  0.75  could indicate a 25% discount (if you don't pay 25% = 0.25, then you do pay 75% = 0.75).

In case you're wondering about discounting first then charging tax, the result is the same because the multiplication can be done in either order.

0.75(1.06p) = 1.06(0.75p)

Step-by-step explanation:

A triangle is a shape with three sides and three angles. There are different types of triangles such as isosceles, equilateral, scalene, obtuse, acute and right angled.

In a right angled triangle, the side with the longest length is known as the hypotenuse and this sides is always opposite to the right angle (90 degrees). Pythagoras states that the square of the hypotenuse is equal to the sum of the square of the remaining sides.

a) u² = h² + b²  (1)

t² = h² + a²     (2)

(a + b)² = t² + u²

(a + b)² = (h² + a²) + (h² + b²)

a² + b² + 2ab = 2h² + a² + b²

2h² = 2ab

h² = ab = 5(3) = 15

u² = h² + b² = 15 + 3² = 24

u = √24

b) u² = h² + b²  (1)

t² = h² + a²     (2)

(a + b)² = t² + u²

(a + b)² = (h² + a²) + (h² + b²)

a² + b² + 2ab = 2h² + a² + b²

2h² = 2ab

h² = ab = 4(2) = 8

h = √8

c) u² = h² + b²  (1)

t² = h² + a²     (2)

(a + b)² = t² + u²

(a + b)² = (h² + a²) + (h² + b²)

a² + b² + 2ab = 2h² + a² + b²

2h² = 2ab

h² = ab = 7(7) = 49

h = 7

u² = h² + b² = 7² + 7² = 98

u = √98

t² = h² + a² = 7² + 7²

t = √98

Answer:

The probability that x equals 19.62 is 0

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In the normal probability distribution, the probability of an exact value, that is, P(X = x) is 0. Thus, the probability that x equals 19.62 is 0

Answer:

- 4

Step-by-step explanation:

h(x) = sin x

f(x) = | 3x - 4 |

g(x) = 2x² - 6

h( [tex]\frac{\pi }{2}[/tex] ) = sin ( [tex]\frac{\pi }{2}[/tex] ) = 1

f ( 1 ) = | 3 × 1 - 4 | = 1

g ( 1 ) = 2( 1² ) - 6 = - 4

g ( f ( h ( [tex]\frac{\pi }{2}[/tex] ) ) ) = - 4

The sum of the interior angles of a triangle is 180 degrees. Therefore, if we add up all of these angles, they will equal 180.

82 + 55 + x = 180

137 + x = 180

x = 43 degrees

Hope this helps!! :)

Answer:

Step-by-step explanation:

55+82+missing angle=180 degree(sum of interior angle of atriangle is 180 degree)

137+missing angle=180

missing angle=180-137

missing angle=43 degree

therefore ur answer is 43 degree.

Answer:

Step-by-step explanation:

Q=event of pulling a quarter (25 cents)

D=event of pulling a dime (10 cents)

N=event of pulling a nickel (5 cents)

P=event of pulling a penny (1 cent)

Simon needs to pull out the penny last, so that the first three coins add up to $0.40.

We assume the coins are wrapped so it is a random choice.

For the first coin, probability of NOT pulling a penny is 3/4,

similarly, for the second coin, probability of NOT pulling a penny is 2/3,

for the third coin, probability of NOT pulling a penny is 1/2,

For all this to happen, we use the multiplication rule

P(3 coins but no penny) = (3/4*2/3*1/2) = 1/4

Answer:

[tex]f(t) = 15 -1.2t[/tex]

[tex]0 \le t \le 12.5[/tex]

[tex]15 \ge f(t)t \ge 0[/tex]

The length of the candle (in inches) 3.6 hours after it was lit is 0.95 inches

Step-by-step explanation:

Given

[tex]a = 15[/tex] ---- candle length

[tex]r =- 1.2[/tex] --- rate (it is negative because the candle length reduces)

Solving (a): The function, f(t)

This is calculated as:

[tex]f(t) = a + rt[/tex]

So, we have:

[tex]f(t) = 15 + -1.2 * t[/tex]

[tex]f(t) = 15 -1.2t[/tex]

Solving (b): The domain

The domain, in this case, represents time from 0 till the candle burns out.

Set [tex]f(t) = 0[/tex] to calculate the time the candle burns out

[tex]f(t) = 15 -1.2t[/tex]

[tex]0 = 15 - 1.2t[/tex]

Collect like terms.

[tex]1.2t = 15[/tex]

Solve for t

[tex]t = 15/1,2[/tex]

[tex]t = 12.5[/tex]

Hence, the domain is: [tex]0 \le t \le 12.5[/tex]

Solving (c): The range

The domain, in this case, represents the candle height from 15 till the candle burns out (0 inches)

Hence, the range is: [tex]15 \ge f(t)t \ge 0[/tex]

Solving (d): [tex]f(t) = 3.6[/tex]

Recall that:[tex]f(t) = 15 -1.2t[/tex]

Sp, we have

[tex]15 - 1.2t - 3.6[/tex]

Collect like terms

[tex]12t =15 -3.6[/tex]

[tex]12t =11.4[/tex]

Divide by 12

[tex]t =0.95[/tex]
