Answer:

Function 1:

The starting point is (0,0.5)

As x increases, y increases

Function 2:

The starting point is (0,3)

As x increases, y decreases

Step-by-step explanation:

In order to find the starting point, we need to plug in x=0.

$y=0.5+3(0)\\\\y=0.5$

$y=3(0.5)^0\\\\y=3(1)\\\\y=3$

As we plug in increasing numbers into function#1, the y-value increases

As we plug in increasing numbers into function #2, the y-value is decreasing

A person owes $1000 on a credit card that charges an interest rate of 2% per month

adelina 88 [10]

Credit card balance each month:

First month: 1020 .00

Second month: 1040.4 0

Third month: 1061,208

Fourth month: 1082.43

Here we have to calculate the interest and add it to capital.

That is, 2% of 1000

First month:

Interest = 1000 (2/100)

Odds1 = 1020

Second month

Capital 1020

Interest = 1020 x 0.02 = 20.4

Odds2 = 1040.4

Third month

Capital = 1040.4

Interest = 1040.4 x 0.02 = 20.808

Odds3 = 1061,208

Fourth month

Capital = 1061,208

Interest = 1061.208 x 0.02 = 21.22

Odds = 1082.43

Therefore the credit card balance each month:

First month: 1020 .00

Second month: 1040.4 0

Third month: 1061,208

Fourth month: 1082.43

A bag contains 50 tokens: 20 pink ,13 blue and 17 purble.if a person selects one token, replaces it,and then selects a second to

stiv31 [10]

Answer:

Step-by-step explanation:

this is independent

20/50= 2/5= 40% of getting pink, probability of getting 2= 20%

13/50=0.26= 26% of getting blue, probability of getting 2= 13%

17/50=0.34=34% of getting purple, probability of getting 2 = 17%

Katena32 [7]

Answer:

$2\sqrt{55}\text{ m/s or }\approx 14.8\text{m/s}$

Step-by-step explanation:

The vertical component of the initial launch can be found using basic trigonometry. In any right triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse. Let the vertical component at launch be $y$ . The magnitude of $40\text{ m/s}$ will be the hypotenuse, and the relevant angle is the angle to the horizontal at launch. Since we're given that the angle of elevation is $60^{\circ}$ , we have:

$\sin 60^{\circ}=\frac{y}{40},\\y=40\sin 60^{\circ},\\y=20\sqrt{3}$ (Recall that $\sin 60^{\circ}=\frac{\sqrt{3}}{2}$ )

Now that we've found the vertical component of the velocity and launch, we can use kinematics equation $v_f^2=v_i^2+2a\Delta y$ to solve this problem, where $v_f/v_i$ is final and initial velocity, respectively, $a$ is acceleration, and $\Delta y$ is distance travelled. The only acceleration is acceleration due to gravity, which is approximately $9.8\:\mathrm{m/s^2}$ . However, since the projectile is moving up and gravity is pulling down, acceleration should be negative, represent the direction of the acceleration.
