Find the x- and y-intercepts of the parabola y=x2+10x+4

Nuetrik [128]

Answer:

x-intercepts: -5 +/- $\sqrt{21}$ . y-intercept: 4

Step-by-step explanation:

For x-intercepts use the quadratic equation

$x= (-b +/-\sqrt{b^2-4ac} )/2a$

Fill in your values:

$x= (-10 +/-\sqrt{100-16} )/2$

And solve

$x=-5 +/- \sqrt{21}$

For y-intercepts set x=0 and solve. In this case, setting x= 0 gives you y=4.

Which choice is equivalent to the quotient below? √64/√4<br>a. √2<br>b. √4/4<br>c. √8/2<br>d. 4

Ksju [112]

Step-by-step explanation:

you did not even try a calculator to find the result ?

64 is 8×8 or 8².

so, sqrt(64) = 8.

similarly for 4 :

4 is 2×2 or 2².

so, sqrt(4) = 2

so,

sqrt(64)/ sqrt(4) = 8 / 2 = 4

so, d. is the right answer.

Answer:

Step-by-step explanation:

1.From the given triangle, ABC, using the proportionality theorem, we get

$\frac{FA}{CA}=\frac{EF}{BC}$

⇒ $\frac{8}{40}=\frac{5}{x}$

⇒ $x=25ft$

Thus, the height will be 25 feet.

2.

Statement Reason

1.∠C≅∠E Given

2. ∠ABC≅∠DBE Vertically opposite angles

3. ΔABC is similar to ΔDBE AA similarity rule.
