Answer:

The y intercept is c

The zeroes are the quadratic formula.

Step-by-step explanation:

Let x=0.

[tex]a(0) {}^{2} + b(0) + c[/tex]

[tex]0 + 0 + c[/tex]

[tex]c[/tex]

The y intercept is c

To find the zeroes,

This gonna to take a minute so the answer to the problem is the quadratic formula.

• Hypotenuse (H) = 15 in

• Base (B) = 12 in

• Perpendicular (P) [x]

By using pythagoras property,

[tex] \longmapsto \sf { H^2 =B^2 + P^2 } [/tex]

[tex] \longmapsto \sf { (15)^2 =(12)^2 +(x)^2 } [/tex]

[tex] \longmapsto \sf { x^2 = (15)^2 - (12)^2 } [/tex]

[tex] \longmapsto \sf { x^2 = 225 - 144 } [/tex]

[tex] \longmapsto \sf { x^2 = 81 } [/tex]

[tex] \longmapsto \sf { x = \sqrt{81} } [/tex]

[tex] \longmapsto \sf \red { x = 9 \: in} [/tex]

So, the value of x (perpendicular) is 9 in.

Step-by-step explanation:

Let x be the number of 10 cent coins

Let y be the number of 20 cent coins

given

[tex]x = y + 12 \\ x - y = 12[/tex]

as equation 1

and

[tex]0.1x + 0.2y = 5.4[/tex]

as equation 2.

Now we will use elimination method to solve simultaneous equations.

Now we multiply equation 1 by 0.2 to eliminate y and solve for x first.

[tex]0.2 \times x - 0.2 \times y = 12 \times 0.2 \\ 0.2x - 0.2y = 2.4[/tex]

Let this new equation be equation 3.

Now use equation 2 + equation 3.

[tex]0.1x + 0.2x + (0.2y + ( - 0.2y)) = 5.4 + 2.4 \\ 0.3x = 7.8 \\ x = 7.8 \div 0.3 \\ = 26[/tex]

Substitute x into equation 1,

[tex]x = y + 12 \\ y + 12 = x \\ y = x - 12 \\ = 26 - 12 \\ = 14[/tex]

Therefore total number of coins = x + y = 26 + 14 = 40

Answer:

in total he has 62 cents

Answer:

B. y = 3x - 14

Step-by-step explanation:

Since the line is parallel, your slope will be 3. You're given a point, so you can use point-slope form to find the equation. Point-slope form is:

y - y1 = m(x - x1) where (x1, y1) is the point that they gave you and m is the slope. So:

y - (-2) = 3(x - 4) --> Start to simplify this by changing - (-2) to +2 and distributing the 3 to (x - 4).

y + 2 = 3x - 12 --> Subtract 2 from both sides.

y = 3x - 14

Answer:

The area of the triangular case = 61.2 square inches

Step-by-step explanation:

P.S - The exact question is -

Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.

To find - What is the area of the triangular case ?

Proof -

Given that,

Base of triangle = [tex]14\frac{2}{5}in[/tex]

Height of triangle = 8.5 in

We know that,

Area of triangle = [tex]\frac{1}{2}*Base*Height[/tex]

                          = [tex]\frac{1}{2}*8.5*14\frac{2}{5}[/tex]

                          = [tex]\frac{1}{2}*8.5*14.4[/tex]

                          = [tex]\frac{1}{2}*122.4[/tex]

                          = 61.2

∴ we get

The area of the triangular case = 61.2 square inches

Answer:

θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Step-by-step explanation:

Since the integration is in cylindrical coordinates, θ is integrated from 0 to 2π.

Since r = cosθ

when θ = 0, r = cos0 = 1

when θ = 2π, r = cos2π = -1

Since the region is bounded below by the plane z = 0, and on the top by the paraboloid z = 3r², z is integrated from z = 0 to z = 3r².

So, when r = 1, z = 3r² = 3(1)² = 3

when r = -1, z = 3r² = 3(-1)² = 3

So, the limits of integration of  

∭f(r,θ,z)dz r dr dθ are θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Answer: 30 & 40

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

0.047

Step-by-step explanation:

The computation of the probability is shown below:

P(dying) = 1 ÷ 150

So,

P(living) = 149 ÷ 150

As There are 120 women.

Now

P(x>=3) = 1 - [P(x=0) + P(x=1) + P(x=2)]

= 1 -[(120 = 0)((1 ÷ 150)^0)((149 ÷ 150)^120) + (120 = 1)((1 ÷ 150)^1)((149 ÷ 150)^119) + (120 = 2)((1 ÷ 150)^2)((149 ÷150)^118)]

P(x>=3)

=0.047

Answer:

Yes.  The city has a lower proportion of accidents by 16-year-old male drivers than the national proportion (16.7% compared to 21%).

Step-by-step explanation:

a) Data and Calculations:

Number of 16-year-old males involved in driver accident during year 2000 = 210

Sample number of drivers = 1,000

National rate of accidents for 16-year-old males for every 1,000 drivers = 21% (210/1,000 * 100)

Random sample of 16-year-old male drivers in a Midwest city = 150

Number of them involved in driver-accidents = 25

Proportion of 16-year-old males involved in driver-accidents = 25/150 * 100 = 16.7%

The city's 16.7% proportion is lower than the national proportion of 21%.

Answer:

m= 2 43/63

Step-by-step explanation:

steps

6 1/9 = 3 3/7 + m

convert mixed numbers into improper fractions 6 1/9 = 55/9

55/9 = 3 3/7 + m

convert mixed numbers into improper fractions 3 3/7 = 24/7

55/9 = 24/7 + m

switch sides

24/7 + m = 55/9

subtract 24/7 from both sides

24/7 + m - 24/7 = 55/9 - 24/7

simplify

m = 169/63

convert improper fraction to mixed number

169/63 = 2 43/63

so your final answer is 2 43/63
