Answer:

The value of k is -2

Step-by-step explanation:

The cut point with the y axis for both graphs occurs when x = 0

We then have:

For f (x):

The cut point for the y axis is:

For g (x):

The cut point with the y axis is:

The value of k is given by the vertical displacement of graph k units.

We then have:

Let's clear k:

Factor expression given the polynomial <br><br> 49x^2 + 100

weqwewe [10]

Answer:

$(7x+10)^2-140x$

Step-by-step explanation:

$(7x+10)^2-140x$

= $(7x+10)(7x+10)-140x$

= $49x^{2} +70x + 70x + 100 - 140x$

= $49x^2 +140x - 140x +100$

= $49x^2+100$

Problem 6-27 A project manager is creating the design for a new engine. He judges that there will be a 50-50 chance that it will

ale4655 [162]

Answer:

Probability = 0.275

Step-by-step explanation:

There are two possible ways for his design to be approved: Being a high-energy engine (H) and being approved or a low-energy energy (L) and being approved.

It is known that there is a 50-50 chance of the engine being high or low-energy.

The probability of approval for each type of engine (E) is given by:

$P(E) = 0.5*A(E)$

Where A(E) is the approval rate for each engine.

Therefore, the probabilities of approval for each type of engine are:

$P(H) = 0.5*0.25\\P(H) =0.125\\P(L) = 0.5*0.30\\P(L) =0.150\\$

The total probability of approval is the sum of both low and high-engine probabilities;

$Probability = P(H)+P(L) =0.125+0.150\\Probability = 0.275$
