depth at point B = 5 m

Step-by-step explanation:

y = -(2/5)x - 1

Point C is located 10 m from the origin O which means that x = 10. Using this value in our equation,

y = -(2/5)(10) - 1

= -4 - 1

= -5

Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B

Tems11 [23]

Answer:

0.75

Step-by-step explanation:

Given,

P(A) = 0.6, P(B) = 0.4, P(C) = 0.2,

P(A ∩ B) = 0.3, P(A ∩ C) = 0.12, P(B ∩ C) = 0.1 and P(A ∩ B ∩ C) = 0.07,

Where,

A = event that the selected student has a Visa card,

B = event that the selected student has a MasterCard,

C = event that the selected student has an American Express card,

We know that,

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(A ∩ C) - P(B ∩ C) + P(A ∩ B ∩ C)

= 0.6 + 0.4 + 0.2 - 0.3 - 0.12 - 0.1 + 0.07

= 0.75

Hence, the probability that the selected student has at least one of the three types of cards is 0.75.

NEED HELP EDU!! WILL GIVE BRAINLEIST!<br> which graph of the cube root function f(x)=^3 √x?

Luden [163]

Answer:

C. $f(x)=\sqrt[3]{-x} -1$

Step-by-step explanation:

Consider graph of the parent function (red curve in attached diagram)

$g(x)=\sqrt[3]{x}$

First, multiply it by -1 to get function

$h(x)=-\sqrt[3]{x}$

Then translate the graph of the function h(x) 1 unit down, then you'll get the function

$f(x)=-\sqrt[3]{x} -1\\ \\ \text{or}\\ \\f(x)=\sqrt[3]{-x} -1$

The graph of the function f(x) is represented by the blue curve in attached diagram

Evaluate the function:<br><br> f(x)=x2−4x, find f(−3)

VikaD [51]

Answer:

f(-3) = 21

Step-by-step explanation:

To solve this, you can replace all x's with -3 and then solve to find the answer.

f(x) = x^2 - 4x

f(-3) = -3^2 - 4(-3)

f(-3) = 9 - (-12)

f(-3) = 21

I hope this helps!
