Answer:

Step-by-step explanation:

I graphed it but you could also use the y intercept to determine which function matches the graph

log(x+1)<u>+3</u>

the +3 at the end of the function makes the y-intercept positive 3

Answer:

$R(x,y) = (0.8,-1.2)$

Step-by-step explanation:

The coordinates of QS are:

$Q(x_1,y_1) = (-2,-6)$

$S(x_2,y_2) = (5,6)$

The ratio is represented as:

$R_{m:n} = 2:3$

Required

Find the coordinates of R

The coordinates of R is calculated by:

$R(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

Substitute values for m, n, x's and y's

$R(x,y) = (\frac{2 * 5 + 3 * -2}{2+3},\frac{2*6 + 3*-6}{2+3})$

$R(x,y) = (\frac{4}{5},\frac{-6}{5})$

$R(x,y) = (0.8,-1.2)$

<em>None of the options is correct</em>

A door alarm works in 72 out of 100 cases and surveillance camera works in 68 out of 100 cases. what is the probability of effec

Rudiy27

A door alarm works in 72 out of 100 cases.

surveillance camera works in 68 out of 100 cases.

The probability that method A is used = 72/100

The probability that method B is used = 68/100

Since both method are used we find the probability of A and B

Probability ( A and B) = $\frac{72}{100}$ * $\frac{68}{100}$

= $\frac{306}{625}$
