discriminant,b2-4ac

=4^2-4×1×4

=16-16=0

Answer: 84.5 units^2

Sides are 13 since the hypotenuse is 13\sqrt{2}.

Area of Triangle: 1/2 b x h

1/2 13 x 13 = 84.5

Step-by-step explanation:

X3+3x2+5x+2x2+6x+10

Collect like terms

X3+5x2+11x+10

The correct expression that shows the P(X) = x³ + 5x² + 11x + 10 as a product of two factors will be;

⇒ (x + 2) (x² + 3x + 5)

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ P(X) = x³ + 5x² + 11x + 10

Now,

Solve the expression for the factors as;

The expression is,

⇒ P(X) = x³ + 5x² + 11x + 10

Since, -2 is the solution of the expression.

Hence, (x + 2) is one of the factor of the expression.

So, Find the second factor by dividing the expression (x³ + 5x² + 11x + 10)

by (x + 2), we get;

x + 2 ) x³ + 5x² + 11x + 10 (x² + 3x + 5

         x³ + 2x²

        --------------

               3x² + 11x

               3x² + 6x

             ------------------

                       5x + 10

                       5x + 10

                   --------------------

                           0

Thus, The second factor = (x² + 3x + 5)

Therefore,        

x³ + 5x² + 11x + 10 = (x + 2) (x² + 3x + 5)

Thus, The correct expression that shows the P(X) = x³ + 5x² + 11x + 10 as a product of two factors will be;

⇒ (x + 2) (x² + 3x + 5)

Answer:

(4√2cos 135,  4√2sin135)

Step-by-step explanation:

determine two pairs of polar coordinates for the point (4, -4) with

Given the rectangular coordintate

r = √4²+(-4)²

r = √16+16

r = √32

r = √16*2

r =4√2

Theta = arctan(-4/4)

theta = arctan(-1)

theta = -45

theta = 180 - 45

theta = 135 degrees

x = rcos theta

y = rsin theta

x = 4√2cos 135

y = 4√2sin135

Answer:

1921.68mm^3

Step-by-step explanation:

Given data

H=17 millimeters

R=6 millimeters.

We know that the expression for the volume of cylinder is

V= πr^2h

substitute

V= 3.14*6^2*17

V= 3.14*36*17

V= 1921.68 mm^3

Hence the volume is 1921.68mm^3

Answer:

72

Step-by-step explanation:

Given that :

Triangle is right angled ;

Leg length = 21 ; hypotenus = 75 ; Length of missing leg =?

From Pythagoras :

Length of leg 2 = sqrt[(hypotenus )² - (length of leg1)²]

Let length of leg 2 = x

x = sqrt[(75 ² - 21²)]

x = sqrt(5625 - 441)

x = sqrt(5184)

x = 72

A right triangle has a leg length of 21 and a hypotenuse of 75. Find the missing leg.

Answer:

It's True

Step-by-step explanation:

1 minute = 60 words

then how many words in 12 minutes?

So, Multiply 12 with 60

12 × 60 = 720

Thus, 720 words can be type in 12 minutes

Answer:

3 and 5

Step-by-step explanation:

Let the two consecutive odd integers be x and x + 2.

Now,

The given statement is

[tex]x^2 + 3 \times (x+2)=24\\x^2 + 3x+6-24 = 0 \\x^2 + 3x-18 = 0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x=3,-6[/tex]

Taking x=3.

Hence, two consecutive odd integers are 3 and 5.

Answer:

2

Step-by-step explanation:

when x is 2 y = 0.

lets start with writing the function's equation;

it has a slope of 2 so 2x + k = y

given in the question when x = -3, y = -10

so k = -4

y = 2x - 4, 0 = 2x-4 then x = 2
