Which of the following is a polynomial with roots negative square root of 5, square root of 5, and 3?x3 − 2x2 − 3x + 6
x3 + 2x2 − 3x − 6
x3 − 3x2 − 5x + 15
x3 + 3x2 − 5x − 15

Answers

Answer 1

Answer: The polynomial with those roots would be:

y = (x + √5)(x - √5)(x - 3)
▬▬▬▬▬▬▬▬▬▬▬ multiply this out to get
y = (x² - 5)(x - 3)

y = x³ - 3x² - 5x +15

Answer 2

Answer:

Answer:

The correct answer is the first one

Step-by-step explanation:

x3 − 2x2 − 3x +

Use the quadratic equation and you will get a polynomial with roots negative square root of 5, square root of 5, and 3

A and B share the cost in a ratio of 3:2 . The cost is ?85; how much does A pay?

Answers

Answer:

The amount of money A pays is $\$51$

Step-by-step explanation:

Let

x-----> amount of money A pays

y-----> amount of money B pays

we know that

$x+y=85$ ------> equation A

$(x)/(y)=(3)/(2)$

$y=(2)/(3)x$ ------> equation B

substitute equation B in equation A and solve for x

$x+((2)/(3)x)=85$

$(5)/(3)x=85$

$x=85*3/5=\$51$

Assuming cos t = .45 and cos w = .89, both t and w are positive, and both t and w determine a terminal point in quadrant 4, then which of the following statements best describes the relationship between t and w?A. t > w
B. w > t
C. It is not possible to tell from the given information.

Answers

The statement which describes the best relationship will be W > t

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Cos - 1 0.45 = 63.3°

Cos - 1 0.89 = 27.1°

The angle for which t is a reference is 296.7°.

The angle for which w is a reference is 332.9°.

Therefore the statement which describes the best relationship will be W > t.

A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ______ units. The point (-7, ______) lies on this circle.How would I do this?

Answers

circle formula
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center
and r=radius

to find the radius
we are given one of the points and the center
distnace from them is the radius
distance formula
D= $\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}$
points (-3,2) and (1,5)
D= $\sqrt{(1-(-3))^(2)+(5-2)^(2)}$
D= $\sqrt{(4)^(2)+(3)^(2)}$
D= $√(16+9)$
D= $√(25)$
D=5

center is -3,2
r=5
input
(x-(-3))^2+(y-2)^2=5^2
(x+3)^2+(y-2)^2=25 is equation
radius =5
input -7 for x and solve for y
(-7+3)^2+(y-2)^2=25
(-4)^2+(y-2)^2=25
16+(y-2)^2=25
minus 16
(y-2)^2=9
sqqrt
y-2=+/-3
add 2
y=2+/-3
y=5 or -1

the point (-7,5) and (7,-1) lie on this circle

radius=5 units
the points (-7,5) and (-7,1) lie on this circle
