y= - 1/3x-1
y = - 3x-1
​

Answer:

sine=opposite/hypotenuse

cosine=adjacent/hypotenuse

tangent=opposite/adjacent

a: 42

b: 135 km/h

Step-by-step explanation:

For part A, you are given the adjacent and opposite side lengths so you need to use the tangent formula. On the calculator, it is tan^-1 (90/100)

For part B, I used the pythagorean theorem and did 100^2+90^2= 18100 and then took the square root of that to get 135.

Answer:

Step-by-step explanation:

Jim drank 2 and 4/5 orange juice

2and 4/5=14/5 orange juice

jack drank  1and 1/10 less than Jim= 11/10 less than Jim

I introduce the whole numbers into the fractions

we will convert the number 14/5 into a fraction that has the denominator 10, by multiplying by 2 both numerator and denominator

(14/5 )*2=28/10

Now we can find out how much juine Jack drank

28/10- 11/10= 17/10

so Jack drank 17/10 orange juice , the fraction can be written also as

1 and 7/10

Answer: The length of one side of the square is 10 sq cm.

Step-by-step explanation:  Area of the rectangle = 4 x 25 = 100 sq cm.

Area of a square = s x s, where s is the length of the side of the square.

So, s x s = 100

Or, s^2 = 100

And, s = sqrt(100) = 10

Answer:

D: (x,y) → (x +1, y - 8)

Step-by-step explanation:

The red shape, KHIJ, is similar to the blue shape, KHIJ.

Looking at the shapes from the points K, Blue K is forward on the x-axis by 1, Hence x + 1.

Lokkin at the same points, but on y-axis this time. Red K is up 2 and Blue K is down 6. 2 + 6 = 8. Since the blue shape is down, make the 8 into -8. Now you have y -8.

Using proportions, given the density value, it is found that the ballons contain 9.8 kilograms of helium.

A proportion is a fraction of a total amount.

In this problem, we have that each ballon contain 0.14 kilograms per cubic meter.

You get 5 ballons, each with 14 cubic meters, hence the total volume is given by:

V = 5 x 14 = 70 m³.

Applying the density, we have that the total mass is given by:

M = 0.14 x 70 = 9.8 kilograms.

Answer:

its 58

Step-by-step explanation:

The measure of angle 2 is 58 degrees

The figure that completes the question is added as an attachment

The given parameters are:

Both angles add up to 90 degrees.

So, we have:

3x - 4 + 4x + 10 = 90

Evaluate the like terms

7x = 84

Divide both sides by 7

x =12

Substitute x =12 in Angle 2 = 4x + 10

Angle 2 = 4 * 12 + 10

Evaluate the expression

Angle 2 = 58

Hence, the measure of angle 2 is 58 degrees

Circle W centre is (-3,0) - (0,-2)* = (-3,-2)

*note that the centre of the circle W is going down by 2 units this only affects the y axis hence the substraction

A dilation of a factor of 2 does not change the centre of the circle rather the radius ( the size of the circle decreases and hence the radius)

So now the radius becomes 8 UNITS/2 = 4UNITS

Answer:

$7,390.15

Step-by-step explanation:

A = $7,390.15

A = P + I where

P (principal) = $6,688.00

I (interest) = $702.15

First, convert R as a percent to r as a decimal

r = R/100

r = 2/100

r = 0.02 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 6,688.00(1 + 0.02/6)^(6)(5)

A = 6,688.00(1 + 0.0033333333333333)^(30)

A = $7,390.15

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $6,688.00 at a rate of 2% per year compounded 6 times per year over 5 years is $7,390.15.

Therefore,required last year population=10000

Answer:

The Correct Answer is 10,000.

Step-by-step explanation:

Becuase The Question itself is providing us that this year it increased by 8%. Then the said that the total population for this year is 10,800. So, that tells us that the 8% equal 800. 10,000+800=10,800.

10,800-800=10,000

The correct answer is 10,000.
