The answer is E. This is distributive property, so you distribute the - to both 7 and 6n. This gives you -7 and -6n. Then you combine the like terms, which would be 8n-6n-7. This equals 2n - 7. I hope this helps!

An airplane is ascending at a constant rate of 15 feet per second what is the change in altitude during 10 minutes of flight

fenix001 [56]

Answer:

9000 ft

Step-by-step explanation:

Given: A airplane is ascending at a constant rate of 15 feet per second,

What we need to know: The change in altitude during 10 minutes of flight,

60 seconds = 1 minute

60 × 10

= 600 seconds

600 × 15

= 9000 ft

Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.

What is the value of the expression shown below

kaheart [24]

value of the expression $\frac{1.6(10^{5})}{0.2(10^{2})}$ or $1.6(10^{5})$ over $0.2(10^{2})$ is $8000$ ( $8 \times 10 ^3$ ).

Step-by-step explanation:

Here we have , to find the value of the expression shown below 1.6 x 10 to the 5th power over 0.2 x 10 to the 2nd power i.e. $1.6(10^{5})$ over $0.2(10^{2})$ :

⇒ $1.6(10^{5})$ over $0.2(10^{2})$

⇒ $\frac{1.6(10^{5})}{0.2(10^{2})}$

multiply and divide by 10 to remove decimals, so we get

⇒ $\frac{16(10^{5})}{2(10^{2})}$

⇒ $\frac{8(2)(10^{5})}{2(10^{2})}$

⇒ $8\frac{(10^{5})}{(10^{2})}$

⇒ $8(10^{(5-2)})$

⇒ $8(10^{3})$

⇒ $8(1000)$

⇒ $8000$

Therefore, value of the expression $\frac{1.6(10^{5})}{0.2(10^{2})}$ or $1.6(10^{5})$ over $0.2(10^{2})$ is $8000$ ( $8 \times 10 ^3$ ).

Instructions: Given the vertex of a quadratic function, find the axis

allsm [11]

The axis of symmetry is x = 5.

In first place, every quadratic function can be expressed as follows:

f(x) = a*x² + b*x + c

where a, b and c are real numbers and a ≠ 0. This way of writing the quadratic function is called polynomial.

The graph of a quadratic function is a parabola. Every parabola is a symmetric curve with respect to a horizontal line called the axis of symmetry. That is, the axis of symmetry is an imaginary line that passes through the middle of the parabola and divides it into two halves that are mirror images of each other.

The point of intersection of the axis of symmetry with the parabola is called the vertex, and it divides the parabola into two branches. That is, the axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Then, being the vertex of the quadratic function (5,7), where the vertex on the x-axis has a value of 5 and on the y-axis a value of 7, the axis of symmetry is x = 5.
