Answer:

X=6

Y=5

Z=14.5

Step-by-step explanation:

the other side of the line is the exact same triangle.

To find X, 24 ÷4=6, therefore x=6

To find Y, 15÷3=5, therefore y=5

To find Z, 28+1=29 29÷2=14.5, therefore z=14.5

If z is not correct then it is probably 14, but the first on should be correc.

Hope this helps! Please mark me as brainlest!

use the formulas for lowering powers to rewrite the expression in terms of the first power of cosine cos^4

Firdavs [7]

The expression cos⁴ θ in terms of the first power of cosine is [ 3 + 2cos 2θ + cos 4θ]/8.

The power-reducing formula, for cosine, is,

cos² θ = (1/2)[1 + cos 2θ].

In the question, we are asked to use the formulas for lowering powers to rewrite the expression in terms of the first power of cosine cos⁴ θ.

We can do it as follows:

cos⁴ θ

= (cos² θ)²

= {(1/2)[1 + cos 2θ]}²

= (1/4)[1 + cos 2θ]²

= (1/4)(1 + 2cos 2θ + cos² 2θ] {Using (a + b)² = a² + 2ab + b²}

= 1/4 + (1/2)cos 2θ + (1/4)(cos ² 2θ)

= 1/4 + (1/2)cos 2θ + (1/4)(1/2)[1 + cos 4θ]

= 1/4 + cos 2θ/4 + 1/8 + cos 4θ/8

= 3/8 + cos 2θ/4 + cos 4θ/8

= [ 3 + 2cos 2θ + cos 4θ]/8.

Thus, the expression cos⁴ θ in terms of the first power of cosine is [ 3 + 2cos 2θ + cos 4θ]/8.

Solve for aaa: a-\left(-3.75\right)=6.11a−(−3.75)=6.11a, minus, left parenthesis, minus, 3, point, 75, right parenthesis, equals

Ganezh [65]

Answer:

Step-by-step explanation:

To isolate a, we add -3.75 to both sides.

a-(-3.75)=6.11

a-(-3.75)+(-3.75)=6.11+(-3.75)

a=6.11+(-3.75) Simplifying, we get:

a=2.36

. The function s(l) = 1.34 √l models the maximum speed s in knots for a sailboat with length l in feet at the waterline. a. Use

trasher [3.6K]

Answer:

The length of the sailboat is 80 feet.

Step-by-step explanation:

The function

$s(l) = 1.34 \sqrt{l}$ ................ (1)

models the maximum speed s in knots for a sailboat with length l in feet at the waterline.

So, using this model we have to find the length of a sailboat with a maximum speed of 12 knots.

Now, from equation (1) we get

$12 = 1.34 \sqrt{l}$

⇒ $\sqrt{l} = 8.955$

⇒ $l = (8.955)^{2} = 80$ feet (Answer)

{The value is round to the nearest foot}
