lisov135 [29]3 years ago
5 0

Answer:

10 units

Step-by-step explanation:

if we're trying to find the width of the arch, then essentially we're trying to find where the arch ends so we can calculate that width right.

you can do this by find the zero's

0 = - (x-5)(x+5)

x = -5,5

simply find the difference between these two values to get width = 10

Value of p,q and r if (2^p)*(3^q)*(7^r)=1176
koban [17]

Answer:

p=3 , q=1 , r=2

Step-by-step explanation:

1176=2*2*2*3*7*7

1176=(2^3)*(3^1)*(7^2)

given that 1176 = (2^p)*(3^q)*(7^r)

Comparing Equation 1 & 2

we get p=3 , q=1, r=2

Textbook: Please write as an expression involving functions of Θ alone.
Setler [38]

Step-by-step explanation:

tan(Θ + 30°)

Use angle sum formula:

tan(A + B) = (tan A + tan B) / (1 − tan A tan B)

So we can write this as:

(tan Θ + tan 30°) / (1 − tan Θ tan 30°)

tan 30° = 1/√3, so:

(tan Θ + 1/√3) / (1 − 1/√3 tan Θ)

Multiply top and bottom by √3:

(√3 tan Θ + 1) / (√3 − tan Θ)
