Hey there!

It’s very much impossible to make this equation without it being an exponent because the result has an exponent in it itself

x⁴ × x²

= (x × x × x × x) + (x × x)

≈ x⁴ ⁺ ²

≈ x⁶

Therefore, the answer should be: x⁶

Answer:

a= c/2

b= (c/2)×√3

side b is the side with the 60 degree angle.

side a is the side with the 30 degree angle.

using the theorem that the side with the 60 degree × 2 = length of side c and the side with the 60 degree × √3 = b.

Answer:

p = 80°

Step-by-step explanation:

The sum of exterior angles is 360°

2p + p - 30 + p + 2p + p - 30 = 360

7p - 60 = 360

7p = 420

p = 60°

Answer:

Pythagoras

Step-by-step explanation:

To figure out how old each philospher was, we can find the difference between their birth and death years.

For Aristotle: 384 - 322 = 62 years old

For Pythagoras: 580 - 495 = 85 years old

For Plato: 428 - 348 = 80

85 > 80 > 62

So, Pythagoras lived the longest out of these three Greek philosophers.

Answer:

tan (A) = 1

Step-by-step explanation:

When sine and cosine are equal to each other, they have the same value. We know that tan (A) = sin (A) / cos (A). If sin (A) and cos (A) are the same, and any number divided by itself equals 1, the final answer must be tan (A) = 1.

The amount of gas in her tank after 8 days given the linear equation g = 213 - 1.6d is 200.2 gallons of gas

The equation

g = 213 - 1.6d

Gas remaining after 8 days

g = 213 - 1.6(8)

= 213 - 12.8

g = 200.2 gallons of gas

As per the  Intersecting Chords theorem, if two chords cross in a circle, the products of the chord segments' measures are equal. The measure of the line segment is DF is 14 units.

If two chords cross in a circle, the products of the chord segments' measures are equal.

As per the Intersecting Chords theorem, the product of DF and FB will be equal to the product of CF and FA, therefore,

DF×FB = CF×FA

(x+8) × 8 = 16 × 7

(x+8) = (16×7)/8

(x+8) = 14

Hence, the measure of the line segment is DF is 14 units.

Answer:

first is 1/8, second is 1/10, third is 1/15, and fourth is 1/16

Step-by-step explanation:

1/2 divided by 4 = .5/4

.5/4 = 0.125

.125 = 1/8

1. 1/8

1/5 = .2

.2/2 = .1

.1 = 1/10

2. 1/10

since 1/3 would be a repeating term, you can change 5 to 5/1

3/1 = 3

1/5 = .2

.2/3 = 1/15

3. 1/15

1/4 divided by four = 1/4 divided by 1/4

1 x 1 = 1

4 x 4 = 16

4. 1/16

The minimum value of the product is -8.

The minimum value is the y value of the lowest point on the graph.

The function y = 2x-8 and we have to find the minimum value of the XY.

Plugging the value of y in the product;

[tex]\rm f(x)=x(2x-8)\\\\f(x)=2x^2-8x[/tex]

f(x) represents an upward parabola and we know that for an upward parabola, the minimum point is the vertex.

So in order to find the minimum value, we find the y coordinate of the vertex of the parabola.

The x-coordinate of the parabola is given by;

[tex]\rm = \dfrac{-b}{2a}\\\\=\dfrac{-8}{2\times 2}\\\\ =\dfrac{-8}{4}\\\\=-2[/tex]

The y -coordinate of the parabola is;

[tex]\rm f(x)=2x^2-8x\\\\f(2)=2(2)^2-8(2)\\\\f(2)=2\times 4-16\\\\ f(2)=8-16\\\\ f(2)=-8[/tex]

The vertex is (2,-8)

Hence, the minimum value of the product is -8.
