Answer:

P=2200 , K=35

Step-by-step explanation:

The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion

P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or

P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2

When given:

k=35, P=2200

Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29

so,

P=2200

k=35

k%5B1%5D=40

and you need P%5B1%5D

2200%2F35%5E2=P%5B1%5D%2F40%5E2

2200%2F1225=P%5B1%5D%2F1600

1.79592=P%5B1%5D%2F1600

1.79592%2A1600=P%5B1%5D

P%5B1%5D=2873.5 watts

If the speed is 30 m per second. Then the power of the car engine will be 1160.8 watts.

A proportionate expression is one in which two items are equal.

The power, P (watts), of a car engine is proportional to the square of its speed s (m/s).

P ∝ s²

P = ks²

We have

s = 35

P = 1580

Then the value of k will be

1580 = (35)² × k

k = 1.2897

Then the equation will be

P = 1.2897s²

If the speed is 30 m per second. Then the power of the car engine will be

P = 1.2897 x 30²

P = 1160.8 watts

Solve the equation 2x2−5x+3=0 by the method of completing square.

Answer:

We have,

2x2−5x+3=0

⇒x2−25x+23=0 (Dividing throughough by 2)

⇒x2−25x=−23 (Shifting the constant term on RHS)

⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)

⇒(x−45)2=1625−23⇒(x−45)2=16

Answer:

Point of contact  ( 3,6)

Step-by-step explanation:

Step(i):-

Given that the points are (1,2) and (6,12)

The ratio 2:3 divides the line segment

The line segment divides m:n externally

[tex](\frac{mx_{2}-nx_{1} }{m-n} ,\frac{mx_{2}-nx_{1} }{m-n} )[/tex]

Step(ii):-

(x₁, y₁) = (1,2) and (x₂, y₂)= (6,12) and m:n =2:3

[tex](\frac{2(6)+3(1) }{2+3} ,\frac{2(12)+3(2) }{2+3} )[/tex]

([tex](\frac{12+3}{5} ,\frac{24+6}{5} )[/tex]

Answer:

There will still be 1.75 pounds of trash left

Step-by-step explanation:

Answer:

1) b= 39.5

2) c= 3.6

3) a=19

Step-by-step explanation:

Use the Pythagorean Theorem to find the missing side length.

"C" is the hypotenuse. Pythagorean Theorem: a^2+b^2=c^2

1) 11^2+b^2=c^41

121+b^2=1681

121-121+b^2=1681-121

b^2=1560

b= 39.5

2) 2^2+3^2=c^2

4+9=c^2

13=c^2

c= 3.6

3) a^2+9^2=21^2

a^2+81=441

a^2+81-81=441-81

a^2=360

a=19

Answer:

4×x = 4x

Step-by-step explanation:

We need to find an expression that is equivalent to 4×x

It means we need to find the product of 4 and x.

Here, 4 is a constant number and x is a variable.

It would mean that,

4×x = 4x

Hence, the correct option is (a) i.e. 4x.

Step-by-step explanation:

I already answered this…

The equation that represents Jayla's current account balance with the initial amount is c=1.07b.

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

[tex]A = P(1+\dfrac{r}{100})^t[/tex]

where, A is the value after t period of time, and,

r is the rate of interest.

Given to us

Jayla's bank account increased by 7% this year.

The amount that Jayla started with is b,

The amount that Jayla has now is c.

We know the general equation for compound interest is given as,

[tex]A = P(1+\dfrac{r}{100})^t[/tex]

Substituting the values we will get,

[tex]c=b(1 + \dfrac{7\%}{100})^1\\c = b(1.07)[/tex]

Hence, the equation that represents Jayla's current account balance with the initial amount is c=1.07b.

Answer:. 400%

Step-by-step explanation:

Divide 160 by 40.

The result is 4.

To Change to a percentage, multiply by 100.

4 × 100 = 400%

The integer number 40 will be 25 percent of the integer number 160.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The percentage of 40 out of 160 will be given as,

P = (40 / 160) x 100

P = 0.25 x 100

P = 25%

The integer number 40 will be 25% of the integer number 160.
