Answer:

46.67 cubic feet

Step-by-step explanation:

The formula for volume of a pyramid is

V = (1/3)Bh      where B is the area of the base, and h is the height.

We are givne B = 35 and h = 4.  Plug those values in and simplify...

V = (1/3)(35)(4)

  V = (1/3)(140)

       V = 140/3

             V = 46 2/3 cubic feet, which is 46.666667, or 46.67 rounded to the nearest hundredth

Answer:

csc(3π/4) = √2

Step-by-step explanation:

∵ csc(3π/4) = 1 ÷ sin(3π/4)

∵ ∠(3π/4) lies on the second quadrant

∴ sin(3π/4) is positive value (according to ASTC Rule)

* ASTC Rule ⇒ (All +ve in 1st quadrant , Sin +ve in 2nd , Tan +ve

                         in 3rd quadrant , Cos +ve in 4th quadrant)

∴ sin(3π/4) = sin(π - α) ⇒ where α is an acute angle

∴ 3π/4 = π - α ⇒ α = π - 3π/4 = π/4

∵ sin²x + cos²x = 1

∵ sin(π/4) = cos(π/4)

∴ 2sin²(π/4) = 1 ⇒ sin²(π/4) = 1/2 ⇒ sin(π/4) = √(1/2)

∴ sin (π/4) = 1/√2  

∴ sin(3π/4) = 1/√2

∴ csc(3π/4) = 1 ÷ 1/√2 = 1 × √2/1 = √2

Answer:

[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the trigonometric identity

• csc x = [tex]\frac{1}{sinx}[/tex]

sin( [tex]\frac{3\pi }{4}[/tex]) = sin ([tex]\frac{\pi }{4}[/tex]) = [tex]\frac{1}{\sqrt{2} }[/tex], hence

csc ([tex]\frac{3\pi }{4}[/tex]) = [tex]\frac{1}{\frac{1}{\sqrt{2} } }[/tex] = [tex]\sqrt{2}[/tex]

Answer:

ok

Step-by-step explanation:

The value of x, given the equation, can be found to be (5y - 35) / 6.

To find the value of x in the equation 6x = 5y - 35, you need to isolate x.

Start with the equation:

6 x = 5 y - 35

To isolate x, divide both sides of the equation by 6:

( 6 x ) / 6 = ( 5 y - 35 ) / 6

Simplify both sides:

x = ( 5 y - 35 ) / 6

So, the value of x is ( 5 y - 35 ) / 6.

Step-by-step explanation:

Let

x----> the time in years

y----> the population

we know that

[tex]100\%+3.8\%=103.8\%=103.8/100=1.038[/tex]

so

[tex]y=40,500(1.038^{x})[/tex]

Final answer:

For Krystal City's population of 40,500 increasing at 3.8% annually, the function is [tex]P(t) = 40500(1 + 0.038)^{t[/tex].

Explanation:

A population function can be represented as:

[tex]P(t) = P_0(1 + r)^{t[/tex]

Where:

For Krystal City with a population of 40,500 and a growth rate of 3.8% annually, the function would be:

Answer:

The diameter is 3600

Step-by-step explanation:

The diameter would be 3600 because in order to find circumference you multiply the diameter times pi which is 3.14, so in order for you to find diameter using circumference, you divide the circumference by 3.14 which then gives you your diameter.

Answer:

Discriminant = 88

Step-by-step explanation:

The general form of quadratic polynomial is:

P(x) = ax² + bx + c ⇒ a is the coefficient of x² , b is the coefficient

of x and c is the numerical term

∵ The discriminant of P(x) = ax² + bx + c is b² - 4ac

∵ P(x) = 2x² + 4x - 9

∴ a = 2 , b = 4 , c = -9

∴ Discriminant = (4)² - 4(2)(-9) = 16 + 72 = 88

Answer:

The discriminant of given polynomial is 88.

Step-by-step explanation:

We have given a polynomial.

2x²+4x-9

We have to find the discriminant of given polynomial.

From polynomial, a  = 2 , b = 4 and c = -9

The formula to find discriminant is

b²-4ac

Putting values in above formula, we have

(4)²-4(2)(-9)

16+72

88

The discriminant of given polynomial is 88.

Answer:

(x + 3)(x + 4)

Step-by-step explanation:

To factor the trinomial

Consider the factors of the constant term ( + 12) which sum to give the coefficient of the x- term ( + 7)

The factors are + 3 and + 4, since

3 × 4 = 12 and 3 + 4 = 7, hence

x² + 7x + 12 = (x + 3)(x + 4)

Thus length can be x + 3 or x + 4 and

the width can be x + 4 or x + 3

Answer:

X 2 + 84 / 7 by 12

Step-by-step explanation:

step 4: x^2+4=10 |work square x and 2|

step 5: x^2=6 |work subtract 4 from both sides|

step 6: X = 2.44 |work find the root of 6|

Answer with step-by-step explanation:

The first three steps of completing the square to solve the quadratic equation [tex]x^2+4x-6=0[/tex] are given in the question which include:

Step 1: [tex]x^2+4x=6[/tex]

Step 2: [tex]x^2+4x+4=6+4[/tex]

Step 3: [tex](x+2)^2=10[/tex]

So the next three steps will be:

Step 4: [tex] \sqrt { ( x + 2 ) ^2 } = \sqrt { 10 } [/tex]

(taking square root on both sides of [tex](x+2)^2=10[/tex] to get [tex]x+2 = +-\sqrt{10}[/tex])

Step 5: solve for x([tex]x+2=3.16[/tex] , ([tex]x+2=-3.16[/tex]

1. 0.5(-12p - 4) =

-6p - 2 is the answer.

Hope this helped!!!!

~Shane

Final answer:

The expression 0.5(-12p - 4) simplifies to -6p - 2 by distributing the 0.5 across each term inside the parentheses, resulting in the multiplication of -12p by 0.5 to get -6p, and -4 by 0.5 to get -2.

Explanation:

The expression 0.5(-12p - 4) can be simplified by distributing the 0.5 across the terms inside the parentheses. This is done by multiplying 0.5 by each term in the parentheses individually. The steps are as follows:

Multiply 0.5 by -12p, which gives us -6p.

Multiply 0.5 by -4, which gives us -2.

Combine these results to get the simplified expression, which is -6p - 2.

Therefore, 0.5(-12p - 4) equals -6p - 2.

Answer:

He spent 35 minutes swimming each day.

Step-by-step explanation:

10x5=50

The multiply by 5 is the numbers of days.

225-50=175

(The 50 minutes subtracted is the time Devon walked)

175 divided by 5 = 35

He spent 35 minutes swimming

Confirm/Check    

35 times 5 =175

( Again, The multiply by 5 is the 5 days.)

175+50= 225

Therefore, He swam 35 minutes each day and walked 10 minutes each day.

He swam 175 minutes in total and walked 50 minutes in total

The number of minutes Devon swam each day is

The word problems must be thoroughly read and understood. Then we can use the given data to make the equations.

He exercised for a total of 225 minutes in the last week.

It is also given that he exercised the amount each day for 5 days.

Therefore, the total number of minutes of exercise per day = 225/5

= 45 minutes.

It is given that he spends 10 minutes everyday walking.

Therefore the total number of time Devon spend swimming = 45 - 10

= 35 minutes

Therefore, we have found that the number of minutes Devon swam each day is 35 minutes.

3.07 feet is your answer :)

Answer:

The radius is 4.5 ft

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3 r^3

Multiply each side by 3/4

121.5 *3/4 = r^3

91.125 = r^3

Take the cube root on each side

(91.125) ^(1/3)= (r^3)^(1/3)

4.5 = r

The radius is 4.5 ft

AB and DC are parallel to each other and both are perpendicular to AD. So the quadrilateral is a right angled trapezoid. Hope this helps! :)

Final answer:

The given quadrilateral cannot be classified into a specific type.

Explanation:

The given quadrilateral has vertices with coordinates (-3,1), (0,3), (5,2), and (-1,-2). To determine the type of quadrilateral, we can find the slopes of the opposite sides. If the slopes are equal, the quadrilateral is a parallelogram. If the slopes are perpendicular, the quadrilateral is a rectangle. If both conditions are satisfied (equal slopes and perpendicular slopes), then the quadrilateral is a square.

Using the formula for slope between two points, we find:

Slope of the first side: (-3,1) to (0,3) -> m1 = (3 - 1) / (0 - (-3)) = 2/3

Slope of the second side: (-1,-2) to (-3,1) -> m2 = (1 - (-2)) / (-3 - (-1)) = 3/2

Slope of the third side: (-3,1) to (5,2) -> m3 = (2 - 1) / (5 - (-3)) = 1/8

Slope of the fourth side: (0,3) to (5,2) -> m4 = (2 - 3) / (5 - 0) = -1/5

Since the slopes of opposite sides are neither equal nor perpendicular, the given quadrilateral is neither a parallelogram, rectangle, nor a square. Therefore, the type of quadrilateral cannot be determined.

The measure of angle XYA is 26 degrees if the YX is a tangent to circle O at point X.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

YX is a tangent to circle O at point X.

Arc XB = 52 dergees

Arc XA = 104 degrees

By the theorem of secant:

m∠XYA  =  1/2(m∠arc XA - m∠arc XB)

= 1/2(104 - 52)

= 26 degrees

Thus, the measure of angle XYA is 26 degrees if the YX is a tangent to circle O at point X.
