Answer

y = [tex]\frac{17}{2}[/tex]

Step-by-step explanation:

-10 + 2y = 7

Add 10 to both sides of the equation

2y = 7 + 10

Add 7 and 10

2y = 17

divide each term in 2y=17 by 2

[tex]\frac{2y }{2} = \frac{17}{2}[/tex]

Divide y by 7

y = [tex]\frac{17}{2}[/tex]

To find the height of the vase, use the formula for the volume of a cone (V = (1/3)πr^2h) and solve for h. Given the base diameter and the volume of the vase, substitute the values into the formula to find the height. The height of the vase is approximately 4 inches.

To find the height of the vase, we can use the formula for the volume of a cone which is V = (1/3)πr^2h, where V is the volume, r is the radius of the base, and h is the height. Given that the base of the vase has a diameter of 6 inches, the radius is half the diameter, which is 3 inches. We also know that the volume of the vase is approximately 113 in.³. We can substitute these values into the formula to find the height:

V = (1/3)π(3^2)h

113 = (1/3)π(9)h

113 = (3/3)π(9)h

113 = (π)(9)h

h = 113 / (π)(9)

h ≈ 4 inches

Therefore, the height of the vase is approximately 4 inches.

By definition, the area of a triangle is given by:

 A = (1/2) * (b) * (h)

 Where,

 b: base

 h: height

 The area of the original triangle is 3 mm² and is dilated by a factor of 6. We have then

 A = (1/2) * (6b) * (6h)

 A = (1/2) * (b) * (h) * (6) * (6)

 A = 3 * (6) * (6)

 A = 108 mm²

 answer

 The area of the dilated triangle is 108 mm²

When a triangle with an original area of 3 mm squared is dilated by a factor of 6, the new area is found by multiplying the original area by the square of the dilation factor. This results in a new area of 108 mm squared.

The question asks about the effect of dilation on the area of a triangle. Specifically, it asks for the new area if a triangle with an original area of 3 mm² is dilated by a factor of 6. When dealing with dilation, the area of a shape changes by the square of the dilation factor. This means that if the dilation factor is 6, the new area will be 62 times the original area. This calculation can be performed as follows:

Original area = 3 mm²

Dilation factor = 6

New area = Original area × (Dilation factor)2 = 3 mm² × 62

New area = 3 mm² × 36 = 108 mm2

Therefore, the area of the dilated triangle is 108 mm²

Answer:

y = 1/2

Step-by-step explanation:

Step 1:  Solve for y

2y + 3 = 4y + 2

2y + 3 - 2 - 2y = 4y + 2 - 2 - 2y

1 / 2 = 2y / 2

1/2 = y

Answer:  y = 1/2

Step-by-step explanation:

2y + 3 = 4y + 2

-2y + 3 = 2

-2y = -1

2y = 1

y = 1/2

y = 0.5

The least amount of money Lana could have is 17 dollars

Lana has x dollars.

Therefore,

Lana money = x  dollars

Kyle has $4 more than twice as much money as Lana.

Kyles money = 4 + 2x

Kyle does not have enough money to buy a video game that costs $56, but he has enough money to buy a textbook that costs $38.

Therefore,

4 + 2x < 56

Answer:

P: (3,0)

Step-by-step explanation:

AB = (9,3)

⅔(9,3) = (6,2)

(-3,-2) + (6,2) = (3,0)

the coordinates of the point P on directed line segment AB that partitions AB in the ratio 2:1 is (3,0).

P=(mx2​+nx1/m+n​​,my2​+ny1/m+n​​).

The formula can be derived by constructing two similar right triangles, as shown below. Their hypotenuses are along the line segment and are in the ratio m : n m:n m:n.

Here, given that,

Given the point A(-3,-2) and B(6, 1),

Let, (x.y) is the coordinates of the point P on directed line segment AB that partitions AB in the ratio 2:1.

Using the formula we get,

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

P=(3,0)

hence, the coordinates of the point P on directed line segment AB that partitions AB in the ratio 2:1 is (3,0).

Answer:

4x + 5y = 80

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5x - 4y = 10 into this form

Subtract 5x from both sides

- 4y = - 5x + 10 ( divide all terms by - 4 )

y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{5}{4}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]  = - [tex]\frac{1}{\frac{5}{4} }[/tex] = - [tex]\frac{4}{5}[/tex], thus

y = - [tex]\frac{4}{5}[/tex] x + c ← is the partial equation

To find c substitute (5, 12) into the partial equation

12 = - 4 + c ⇒ c = 12 + 4 = 16

y = - [tex]\frac{4}{5}[/tex] x + 16 ← in slope- intercept form

Multiply through by 5

5y = - 4x + 80 ( add 4x to both sides )

4x + 5y = 80 ← in standard form

The equation of line perpendicular to [tex]5x-4y=10[/tex] and passing through the point (5,12) is [tex]y=-\frac{4}{5}+16[/tex]

The line given in the problem is in Standard Form. The standard form of a linear equation is: [tex]Ax+By=C[/tex]

Where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

[tex]5x-4y=10[/tex]

The slope of an equation in standard form is: [tex]m=-\frac{A}{B}[/tex]. Substituting the values from the equation in the problem gives:

[tex]m=-\frac{5}{(-4)} =\frac{5}{4}[/tex]

Let's call the slope of the line perpendicular to this line [tex]m_{p}[/tex] . The slope of a perpendicular line is:

[tex]m_{p} =-\frac{1}{m} =-\frac{4}{5}[/tex]

We can now use the point-slope formula to find the equation of the line. The point-slope formula states: [tex](y-y_{1})=m(x-x_{1})[/tex]

[tex]y-12=-\frac{4}{5} (x-5)[/tex]

[tex]5(y-12)=-4(x-5)\\5y-60=-4x+20\\5y=-4x+80\\y=-\frac{4}{5}x+16[/tex]

Therefore, the equation of line perpendicular to [tex]5x-4y=10[/tex] and passing through the point (5,12) is [tex]y=-\frac{4}{5}+16[/tex]

Final answer:

The exponential function that goes through the points (0,6) and (2,96) is y = 6 * 4^x, where 6 is the initial value (a) and 4 is the base growth rate (b).

Explanation:

The student is asking for an exponential function in the form y = ab^x that passes through the points (0,6) and (2,96).

To find this function, we must determine the values of 'a' and 'b'. Since the function passes through the point (0,6), if we substitute x = 0, we get y = a * b^0. Since any number raised to the power of 0 is 1, it simplifies to y = a. Therefore, a = 6.

Next, we substitute the second point (2,96) into the original equation with our known value for 'a': 96 = 6 * b^2. To solve for 'b', we divide both sides of the equation by 6, resulting in 16 = b^2. Finding the positive square root of 16 gives us b = 4.

Therefore, the exponential function is y = 6 * 4^x.

The exponential function that goes through the points [tex]\((0, 6)\)[/tex] and [tex]\((2, 96)\)[/tex] is [tex]y = 6 \times 4^x[/tex]

To find the exponential function in the form [tex]\( y = ab^x \)[/tex] that goes through the points [tex]\((0, 6)\)[/tex] and [tex]\((2, 96)\)[/tex], we need to determine the values of [tex]\(a\)[/tex] and [tex]\(b\)[/tex].

1. Use the point [tex]\((0, 6)\)[/tex]

When [tex]\( x = 0 \), \( y = 6 \).[/tex]

[tex]\[6 = ab^0\][/tex]

Since [tex]\( b^0 = 1 \)[/tex]

[tex]\[6 = a \times 1\][/tex]

Therefore, [tex]\( a = 6 \).[/tex]

2. Use the point [tex]\((2, 96)\)[/tex]

When [tex]\( x = 2 \), \( y = 96 \)[/tex]

[tex]\[96 = 6b^2\][/tex]

Solving for [tex]\( b^2 \)[/tex]

[tex]\[b^2 = \frac{96}{6} = 16\][/tex]

Taking the square root of both sides:

[tex]\[b = 4\][/tex]

Thus, the exponential function is:

[tex]\[y = 6 \times 4^x\][/tex]

To verify, we can check both points:

For [tex]\((0, 6)\)[/tex]

[tex]\[y = 6 \times 4^0 = 6 \times 1 = 6\][/tex]

For [tex]\((2, 96)\)[/tex]

[tex]\[y = 6 \times 4^2 = 6 \times 16 = 96\][/tex]

Measure of ∠B is 110°

Step-by-step explanation:

In a parallelogram, opposite angles are equal.

⇒ ∠B = ∠D

⇒ ∠B = (5x + 10)°

Now, angles in a parallelogram are equal to 360°.

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ (3x + y)° + (5x + 10)° + (5y + 20)° + (5x + 10)° = 360°

⇒ 13x + 6y + 40° = 360°

⇒ 13x + 6y = 320°  ------ (1)

Also, adjacent angles in a parallelogram are supplementary.

⇒ ∠A + ∠D = 180°

⇒ (3x + y)° + (5x + 10)° = 180°

⇒ 8x + y = 170° ----------- (2)

13x + 6y = 320

48x + 6y = 1020  (After multiplying eq. 2 with 6 to make coefficients equal)

Subtract (2) from (1)

⇒ -35x = -700

∴ x = 20

⇒ (5x + 10)° = 100 + 10 = 110°

Answer:

110°

Step-by-step explanation:

Angle A = Angle C

3x + y = 5y + 20

3x = 4y + 20

Angle C + Angle D = 180

5y + 20 + 5x + 10 = 180

5x + 5y = 150

x + y = 30

x = 30 - y

3(30 - y) = 4y + 20

90 - 3y = 4y + 20

7y = 70

y = 10

x = 30 - 10

x = 20

Angle B = Angle D

= 5(20) + 10

= 110°
