The car is speeding at a rate of 33.3mph

<h3>Speed and distance of an object</h3>

If a certain car going 60 mph can stop in 180 ft, then we can express this as:

  • 60mph = 180ft

To determine the speed for a car traveling at 100ft, we will have:

  • x = 100ft

Take the ratio of the expression

60/x = 180/100
180x = 6000

x = 33.3mph

Hence the car is speeding at a rate of 33.3mph

If g(x)=4x^2-16 we’re shifted 9 united to the right and 1 down, what would the new equation be?
Inessa05 [86]

Shown in the graph

<h2>Explanation:</h2>

Using graph tools we can graph the function:

g(x)=4x^2-16

which is the red graph shown below. As you can see, this is a parabola. The rule for vertical and horizontal shifts is as follows:

Let \ c \ be \ a \ positive \ real \ number. \ \mathbf{Vertical \ and \ horizontal \ shifts} \\ in \ the \ graph \ of \ y=f(x) \ are \ represented \ as \ follows:

\bullet \ Vertical \ shift \ c \ units \ \mathbf{upward}: \\ h(x)=f(x)+c \\ \\ \bullet \ Vertical \ shift \ c \ units \ \mathbf{downward}: \\ h(x)=f(x)-c \\ \\ \bullet \ Horizontal \ shift \ c \ units \ to \ the \ right \ \mathbf{right}: \\ h(x)=f(x-c) \\ \\ \bullet \ Horizontal \ shift \ c \ units \ to \ the \ left \ \mathbf{left}: \\ h(x)=f(x+c)

Therefore, If we shift the red graph 9 units to the right and 1 down, our new function (let's call it h(x)) will be:

h(x)=4\left(x-9\right)^{2}-16-1 \\ \\ Simplifying: \\ \\ h(x)=4\left(x-9\right)^{2}-17

This graph is the blue graph below. Let's verify the transformation taking the vertex of the red graph:

(0,-16)

By translating the 9 units to the right and 1 down the vertex is also translated by the same rule, so:

New \ vertex: \\ \\ (0+9,-16-1) \\ \\ (9,-17)

Savings account with 200$ and receive 4% interest for 7 years, how much would be in the account?
Fantom [35]

Answer:

256

Step-by-step explanation:

To calculate these kinds of things, I multiply the principal (200), the interest rate (0.04) and the time (7). This results in 56. However, since the question is how much would be in the account, it would be 200+56 which is 256.

Is 1/2+4/9 greater than 1
ladessa [460]
1/2 x 9/9 = 9/18
4/9 x 2/2 = 8/18

9/18 + 8/18 = 17/18

17/18 is less than 1

so your answer is false

hope this helps
