Answer:

Correct option is:

A. -1 and 10

Step-by-step explanation:

If a,b are the roots of Ax²+Bx+C=0

then, a+b= -B/A

The polynomial (x+ p)(x+q) has roots -p and -q

x²+ 9x +10= (x+ p)(x+q)

i.e. -p and -q are roots of x²+ 9x +10

Hence, -p-q= -9

i.e. p+q=9

Hence, The correct value of pa and q are:

p= -1 and q= 10

i.e. Correct option is:

A. -1 and 10

Radioactive Waste The rate at which radioactive waste is entering the atmosphere at time t is decreasing and is given by Pe^-kt,

Dmitry_Shevchenko [17]

Answer:

$\displaystyle{\int^{\infty}_0 {50e^{-0.04t}}\, dt}=1250$

Step-by-step explanation:

Given:

$T =\displaystyle{\int^{\infty}_0 {Pe^{-kt}} \, dt}$

where,

T = total amount of waste

P = 50, the initial rate

k = 0.04

t = time

$T =\displaystyle{\int^{\infty}_0 {50e^{-0.04t}} \, dt}$

now we need to solve this integral!

$T =\displaystyle{50\int^{\infty}_0 {e^{-0.04t}} \, dt}$

$T = \left|50\left(\dfrac{e^{-0.04t}}{-0.04}\right)\right|^{\infty}_0$

$T = \left|-1250e^{-0.04t}\right|^{\infty}_0$

$T = (-1250e^{-0.04(\infty)})-(-1250e^{-0.04(0)})$

when any number has a power of negative infinity it is 0. because: $a^-{\infty} = \dfrac{1}{a^{\infty}} = \dfrac{1}{\infty} = 0$ , like something being divided by a very large number!

$T = (-1250(0))-(-1250e^0)$

$T = 1250$

this is the total amount of waste

What relationships exist between the figures on the coordinate grid below? Please explain reasoning

Likurg_2 [28]

Answer:

Similar

Step-by-step explanation:

There are two triangles in this picture, ABC and A'B'C'. Triangle ABC have 2 base and 2 height. Triangle A'B'C' have 6 base and 6 height, which is 3 times larger than ABC. When two objects have the same shape but different size, it is called similar.

A similar object can be made by using dilation transformation. In this case, ABC triangle have been dilated by 3 times to make A'B'C'
