PLEASE HELP <br> WHAT ARE THE coordinates for the center of the hyperbola??

solong [7]

Answer:

The coordinates of the center of the hyperbola are (1,-3)

Step-by-step explanation:

Equation of a hyperbola:

The equation of a hyperbola with center $(x_0,y_0)$ is given by:

$\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1$

In this question, we have that:

$-x_0 = -1 \rightarrow x_0 = 1$

$-y_0 = 3 \rightarrow y_0 = -3$

The coordinates of the center of the hyperbola are (1,-3)

Answer:

Scatterplot

Step-by-step explanation:

Bivariate data means that the data is in two variables. For example, if the height of the students is plotted against their age, this data will be the bivariate data.

A bivariate data is represented using the graph known as Scatter Plot. One variable is plotted along x-axis and second variable is plotted against y-axis. After plotting the two variables we can observe the relation(association) between the two variable using the line of best-fit which models the relation between the two variables.

So, the answer to this question is Scatterplot.

Fermium-253 has a half life of three days. A sample contains 400 g. How long will it take for the sample to decay to 100 g?

NemiM [27]

After the first three days, the sample size will be half of the initial; therefore, 400g/2= 200g. However, it is asking how long will it take to decay to 100g, so we will take 200g/2= 100g, which will take another three days. It will take 2 half-lives, which will encompass 6 days.

Given that A varies directly as B and inversely as C and that; A=12 when B=3 and C=2. Find B when A=10 and C=1.5

maria [59]

Answer:

B = 1.875

Step-by-step explanation:

given that A varies directly as B and inversely as C then the equation relating them is

A = $\frac{kB}{C}$ ← k is the constant of variation
