Answer:(d): y=ax+b (a≠0); (d1)y=-4x+13

because of (d)⊥(d1) --> a.(-4)=-1 --> a= $\frac{1}{4}$

(d): y= $\frac{1}{4}x$ +b. (d) pass through P(-1;-2) so we have

-2=(1/4).(-1)+b ---> b= $\frac{-7}{4}$

(d) y= $\frac{1}{4}x+ \frac{-7}{4}$

Answer:

Step-by-step explanation:

Assuming this is the slope equation

-2 is the slope

x is point x

5 is the y intercept

y is point y

the regular equation it y = mx + b

the slope is negative so it is decreasing aka gooing down

sorryy if this is the wrong answer to your question

Andreas93 [3]

Answer:

Maybe -12?

Answer:

$P_{native}\:=\:3.186\times10^8$

Step-by-step explanation:

Population that didn't immigrated = Total Population - Population that immigrated

$P_{native}\:=\:P_{total}\:-\:P_{immigrants}$

$P_{native}\:=\:3.2\times 10^8-1.4\times 10^6$

$=3.2\times 10^8-1.4\times 10^6\times \frac{100}{100}\\\\=3.2\times 10^8-\frac{1.4}{100}\times 10^6\times 10^2\\\\=3.2\times 10^8-0.014\times 10^{6+2}\\\\=3.2\times 10^8-0.014\times 10^8\\\\=10^8\left(3.2-0.014\right)\\\\=3.186\times10^8$

A cone has a diameter of 4 centimeters and a height that is 6 times the diameter. Using 3.14 for pi, which of the following can

Verizon [17]

Answer:

Option B is correct that is volume of the cone is one over three (3.14)(2cm)^2(24).

Step-by-step explanation:

Given: Diameter of the Cone , d = 4 cm

Height of the cone , h = 6 × d = 6 × 4 = 24 cm

To find: Volume of cone.

radius of cone , r = $\frac{d}{2}=\frac{4}{2}=2\:cm$

Volume of the cone is given by the following formula,

$Volume=\frac{1}{3}\pi r^2h$

$Volume=\frac{1}{3}(3.14)(2)^2(24)$

$Volume=\frac{1}{3}(3.14)(4)(24)$

Therefore, Option B is correct that is volume of the cone is one over three (3.14)(2cm)^2(24).
