Use the discriminant to determine which graph could represent the equation. y=x^2+4x+5

lidiya [134]

ANSWER

See attachment.

EXPLANATION

The given function is

$y = {x}^{2} + 4x + 5$

When we compare this function to

$y = a{x}^{2} + bx + c$

We have a=1, b=4 and c=5

We put this inside the formula for the discriminant, which is

$D = {b}^{2} - 4ac$

$D = {4}^{2} - 4(1)(5)$

$D = 16 - 20 = - 4$

Since the discriminant is negative, the function has no x-intercepts.

The graph of this function is the one hanging in the air above the x-axis and opens upwards.

SPIDER ~ HNYCMB<br> Find NY, YC, CM, AND MB.

zzz [600]

Answer:

HN = 66, NY = 27, YC = 30, CM = 27, MB = 42,

Step-by-step explanation:

When comparing the two shapes, SPIDER is 0.75 times larger than HNYCMB. Besides this small detail they are the same shape. We can determine this by identifying which sides are most similar and dividing them, if SP "=" HN, then to find the rate at which figure HNYCMB shrank is to divide SP by HN. 66/88 is 0.75. By multipying the sides of figure SPIDER by 0.75, we get our answers.

HN ~ SP, 66 = 88 * 0.75, HN = 66

NY ~ SR, 27 = 36 * 0.75, NY = 27

YC ~ RE, 30 = 40 * 0.75, YC = 30

CM ~ ED, 27 = 36 * 0.75, CM = 27

MB ~ DI, 42 = 56 * 0.75, MB = 42

BH ~ PI, BH = ? Try this one by yourself for understanding

I need help explanation if possible

viva [34]

Answer:

y = 16.

Step-by-step explanation:

The ratio of corresponding sides of similar triangles are the same.

The small and large triangles are similar ( - that is corresponding angles are congruent).

So 2/(2+8) = x / 20

2/10 = x/20

10x = 40

x = 4.

Therefore y = 20 -4 = 16.

The population of a species of rabbit triples every year. This

jok3333 [9.3K]

Answer:

"4" represents that there are 4 rabbit in the beginning.

Step-by-step explanation:

Given that the population of a species of rabbit triples every year. This

can be modeled by function $f\left(x\right)=4\left(3\right)^x$ and $f(5) = 972$ .

Now we need to find about what does the 4 represent in the given function.

We know that exponential function is given by $f\left(x\right)=a\left(b\right)^x$ . Where "a" represents the initial amount.

we have a=4 in given function $f\left(x\right)=4\left(3\right)^x$ .

So that means "4" represents that there are 4 rabbit in the beginning.
