Answer:

Step-by-step explanation:

x² + 3x - 10

p + q needs to equal the b-value.

Since b = 3, then the sum of p = -2 and q = 5 works.

⇒ (x - 2)(x + 5)

Answer:

C) English

Step-by-step explanation:

I don't really know how to explain it, so I'll show you instead.

For science, there are 6 of 6 correct answers with a 0.5 chance of answering correctly.

So,

0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 = 0.016

For English, there are 4 of 4 correct answers with a 0.25 chance of answering correctly.

So,

0.25 x 0.25 x 0.25 x 0.25 = 0.004

They will have to study English (0.004) because it is lower than science (0.016).

(09.01) A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsiu

lukranit [14]

Answer:

x-intercept:

A line that crosses the graph at x-axis.

i.e substitute y = 0 and solve for x.

As per the statement:

A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water

Given the graph:

$y = -2x^2+20x+400$

Substitute y = 0 we have;

$-2x^2+20x+400 = 0$

⇒ $-2(x^2-10x-200) = 0$

⇒ $x^2-10x-200 =0$

⇒ $x^2-20x+10x-200 =0$

⇒ $x(x-20)+10(x-20)=0$

⇒ $(x-20)(x+10)=0$

By zero product property we have;

x-20 =0 and x+10 = 0

⇒x = 20 and x = -10

Therefore, the x-intercept represents the water has no larvae at −10 degrees Celsius and 20 degrees Celsius.
