What is the equation of a quadratic function that has a directrix of y=4 and a focus of (-2,-2)

Answer:

[0, ∞)

Step-by-step explanation:

The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).

If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).

Answer:

$1,377

Step-by-step explanation:

the way that I did it-

100-25=75

1700x0.75=1275

8%=0.08, just add a 1 to the sales tax whenever you are calculating that.

1275x1.08=1377

therefore it is $1,377

Step-by-step explanation:

the sum of interior angles in a triangle is 180°

so

2x+2+12x-8+6x+6=180

20x=180

x=180/20=9

so

m<A =6x+6=6*9+6=54+6=60

m<M=12x-8=12*9-8=100

m<N=2x+2=2*9+2=18+2=20

MAN is an obtuse triangle

because of 100° angle

Answer:

A. coefficient

Step-by-step explanation:

A constant is the number that isn't with any variable, which in this case, the constant would be 15.

A variable is a unknown value, which in this case, the variable would be x.

The term are the numbers in the equation, which in this case, the terms would be 7x and 15.

The 7 in the expression 7x + 15 is the coefficient.

The correct option is A.

A term is composed of one mathematical expression. A single variable (a letter), a single integer (positive or negative), or a number of variables that have been multiplied but never added or subtracted are all examples of single variables. There is a number in front of certain words that are variables. A word or phrase is preceded by a coefficient.

In general, a coefficient is the numerical factor of a term that contains a variable. In this case, the term containing the variable x is 7x, and the coefficient of this term is 7. The term 15 is a constant term, which is a term that does not contain any variables.

Answer:

$4162.4

Step-by-step explanation:

As per the question statement,

The computer monitors are in cuboid structure.

Width of computer monitors = 22 inches

Length of computer monitors = 22 inches

Thickness of computer monitors = 2 inches

Average cost of production per cubic inch = $0.43

To find:

Cost to the company to make 10 monitors.

Solution:

Volume of a cuboid is given as following:

[tex]Volume = Length \times Width \times Height[/tex]

Volume of one computer monitor as per the given dimensions = [tex]22\times 22 \times 2[/tex] = 968 cubic inches

Volume of 10 such monitors = 968 [tex]\times[/tex] 10 = 9680 cubic inches

Cost of manufacturing of 1 cubic inch = $0.43

Cost of manufacturing of 9680 cubic inch = $0.43 [tex]\times[/tex] 9680 = $4162.4

Answer:

it's 42 my bad...

Step-by-step explanation:

Answer:

Choice C 42 in^2

Step-by-step explanation:

Area of a triangle= 1/2(b)(h)

= 1/2(3)(6)

= 9

Since there is two triangles we can do:

9(2) = 18

Area of a rectangle = (b)(h)

= (4)(6)

= 24

24+18 = 42 in^2

Answer:

Step-by-step explanation:

A of base: l ×w =5×4=20cmsquared

Missing length of c=a+b=c

C=6+2

C=8cm

A of side 1= b×h÷2 ×2

= 5×8÷2×2

= 40 ÷2×2

=20 ×2

= 40 cm squared

A of side 2= b×h÷2×2

= 4×8÷2×2

= 32 ÷ 2 ×2

= 16 ×2

= 32cm squared

Total of pyramid is = area of base + A

off side 1 + A if side 2

=92 cm cubed

The price of each admission is 7

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Total amount paid for admission =  $245

Total number of people=35

So,

let the price of admission be x

So, 35x= 245

Now dividing both side by 35

35x/35=245/35

x= 7

Hence, price of each admission is 7.

Answer:

slope: 20/3 parallel

Step-by-step explanation:

y1-y2/x1-x2 gives you slope(30--10/12-6). Plot the points, create line segments, you'll find that they are parallel.

Answer:

1. 6[tex]\frac{2}{3}[/tex]

2. Parallel

Step-by-step explanation:

To find the slope, you need to find the [tex]\frac{rise}{run}[/tex] between two points.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{30-(-10)}{12-6}[/tex]

     = [tex]\frac{40}{6}[/tex]

     = 6[tex]\frac{2}{3}[/tex]

If a graph has more than a point on the y-axis even though the x-axis remains the same, it means that it is a vertical line. Since Graph 1 has (-1) on the x-axis but there are two points on the y-axis, 4 & (-9), it is a vertical graph. Since Graph 2 has (11) on the x-axis but there are two points on the y-axis, (-2) & 6, it is also a vertical graph. Thus, both graphs are parallel.

Answer:

Let's solve your system by substitution.

x+2y=6;x−y=3

Step: Solvex+2y=6for x:

x+2y=6

x+2y+−2y=6+−2y(Add -2y to both sides)

x=−2y+6

Step: Substitute−2y+6forxinx−y=3:

x−y=3

−2y+6−y=3

−3y+6=3(Simplify both sides of the equation)

−3y+6+−6=3+−6(Add -6 to both sides)

−3y=−3

−3y

−3

=

−3

(Divide both sides by -3)

Answer:

$65 ≤ x ≤ $135

Step-by-step explanation:

Now, one should know the meaning of compound inequality. A compound inequality is an inequality that simply combines the two simple inequalities.

Now, in an inequality, three relations are performed, equal to, less than, and greater than. You can combine 'equal to' with 'less than' or 'greater than' according to the situation given.

Notice that in the given sign

≤

the value on the left side of the pointed side will be small or lesser than the value on the right side. Also notify that if inverted, like this ≥

The value of the left side will be greater. This means the value at the pointed side will always be smaller. The lower bar is a sign of equal to

if this is written

x ≤ 3

It means that x can be equal to three or any value less than 3 means 2,1,0,-1, etc.

Now in the question given, it is stated that money should be not less than $65 means it can either be $65 or more but not less than it. Let's assume 'x' as the amount required,

So one inequality is

$65 ≤ x

The second condition which is amount should be no more than $135, means it can be $135 or less, so inequality is

x ≤ $135

Remember that we use AND in the answer because both statements of inequality need to be fulfilled or satisfied.

Answer:

x=20

Step-by-step explanation:

By the Triangle Sum Theorem, the angles of a triangle add up to 180. So we can set up the equation like this:

2x-10+70+4x=180

Combine Like terms

6x+60=180

Subtract 60 from both sides

6x=120

Divide by 6 to isolate the variable

x=20

Answer:x= 20

Step-by-step explanation:

As the equation of three angles of a triangle is 180°,

Then, 2x-10+70+4x=180

6x=120

So,x= 20

Answer: -77[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

Answer:

m∠DBC is 43°

Step-by-step explanation:

Let us solve the question

∵ D is in the interior of ∠ABC

→ That means D divides ∠ABC into two angles ABD and DBC

∴ m∠ABD + m∠DBC = m∠ABC

∵ m∠ABD = (3x + 5)°

∵ m∠DBC = (5x - 7)°

∵ m∠ABC = 78°

→ Substitute them in the equation above

∴ 3x + 5 + 5x - 7 = 78

→ Add the like terms in the left side

∵ (3x + 5x) + (5 + -7) = 78

∴ 8x + -2 = 78

∴ 8x - 2 = 78

→ Add 2 to both sides

∴ 8x -2 + 2 = 78 + 2

∴ 8x = 80

→ Divide both sides by 8

∴ x = 10

→ To find m∠DBC, substitute x by 10 in its measure

∵ m∠DBC = 5(10) - 7

∴ m∠DBC = 50 - 7

∴ m∠DBC = 43°
