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]

The equation of the given circle is [tex](x-6)^{2}+(y+9)^{2}=100.[/tex]

Step-by-step explanation:

Step 1:

The equation of a circle with its center at (h, k) and a radius of r is given by

[tex](x-h)^{2}+(y-k)^{2}=r^{2}.[/tex]

The h value is the x coordinate and the k value is the y coordinates, so (h, k) is (6, -9).

The radius is given as 10 so [tex]r =10[/tex] and [tex]r^{2} = 100.[/tex]

Step 2:

By substituting the values we know, we get

[tex](x-h)^{2}+(y-k)^{2}=r^{2} = (x-6)^{2}+(y-(-9))^{2}=10^{2}.[/tex]

So the equation of the given circle is

[tex](x-6)^{2}+(y+9)^{2}=100.[/tex]

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]

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°

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).

Im not sure it depends on the pattern? lol

The pattern described in the table is the value of b is 5 times the value of a.

A pattern is defined as a sequence of repeating objects, shapes or numbers. We can relate a pattern to any type of event or object. A pattern has a rule that tells us which objects belong to the pattern and which objects do not belong to the pattern.

Given is a table,

a - 0 1 2 3 4

b - 0 5 10 15 20,

We can see, that the values in the b row are 5, 10, 15, 20 they are the multiple of 5

And values in row a, are 1, 2, 3, 4, we can see they are the numbers which are related to row b, in a way that, values in b are 5 times the value of a,

1 × 5 = 5

2 × 5 = 10

3 × 5 = 15

4 × 5 = 20

5 × 5 = 25

Therefore, we can say that the numbers in b are 5 times the corresponding value of the a,
