The wind speed near the center of a tornado is represented by the equation S=93logd+65, where d is the distance, in miles, that
dezoksy [38]

Answer:

Therefore,

Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.

Step-by-step explanation:

Given:

The wind speed near the center of a tornado is represented by the equation,

S=93\log d+65

Where,

d =  the distance, in miles

S = the wind speed, in miles per hour.

To Find:

S = ? at d = 4 miles

Solution:

We have

S=93\log d+65        .........Given

Substitute d = 4 in above equation we get,

S=93\log 4 + 65=93\times 0.602 +65=120.99

Rounding the answer to the nearest tenth we have

S=121.0\ mph

Therefore,

Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.

Help!!!<br> Find the zeros of the quadratic equation by factoring.<br><br> x^2+4x-5=0
weqwewe [10]

Answer:

x = -5, 1

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from ax^2 + bx + c.

-1 and 5 multiply to -5 and add to 4.

x^2+4x-5 = (x+5)(x-1)

The zeros are the factors set equal to 0 and solved.

(x+5) = 0

x=-5

(x-1) = 0

x=1
