$(-x^3+26x^2-7-13)+(6x^4-x^3+8x+27)\\\\=-x^3+26x^2-7-13+6x^4-x^3+8x+27\\\\=6x^4+(-x^3-x^3)+26x^2+8x+(27-7-13)\\\\=\boxed{6x^4-2x^3+26x^2+8x+7}$

Bart lives 6 blocks from his grandparents. Melinda lives 8 blocks farther from her grandparents as bart does. How many blocks do

faltersainse [42]

Answer: Melinda lives 14 blocks from his grandparents.

Step-by-step explanation:

Since we have given that

Distance at which Bart lives from his grandparents = 6 blocks

Distance at which Melinda lives from his grandparents as Bart does = 8 blocks

As we have given that Melinda lives 8 blocks farther than the Bart does from the grandparents ,

So, we use the addition operation to calculate the farther distance.

Total distance at which Melinda live from her grandparents is given by

$8+6=14\ blocks$

Hence, Melinda lives 14 blocks from his grandparents.

Identify the correct equation that describe the relationship between a sine and cosine wave. a. v(t) = A sin (2πft + π/2) = A co

Flauer [41]

Answer:

A. v(t) = sin (2πft + π/2) = A cos (2πft)

Step-by-step explanation:

According to trigonometry friction, the following relationship are true;

Sin(A+B) = sinAcosB + cosAsinB

We will be using this relationship to check which option is true.

Wave equation is represented as shown;

y(t) = Asin(2πft±theta)

For positive displacement,

y(t) = Asin(2πft+theta)

If theta = π/2

y(t) = Asin(2πft+π/2)

y(t) = A[ sin 2πftcosπ/2 + cos2πft sin π/2]

Since sinπ/2 = 1 and cos (π/2) = 0

y(t) = A[ sin 2πft (0)+ cos2πft (1)]

y(t) = A[0+ cos2πft]

y(t) = Acos2πft

Hence the expression that is true is expressed as;

v(t) = Asin(2πft+π/2) = Acos2πft
