The full question is depicted in the attached image.

Given that

the circle's radius r is 4 units,

in triangle OST,
each side OT and OS measures 4 units,
with m∠OST = 60°. Therefore, cos 60°=(ST/2)/r leads to ST=2*r*cos 60° which equals 2*4*(1/2) resulting in ST = 4 units.
Thus,
triangle OST is an equilateral triangle.

Part a) results in
ST = 4 units

Part b)
To determine PT,
in triangle POT,
m∠POT = (180°-60°) equals 120°.
Furthermore, m∠OTP = 30°. The relationship cos 30°=(PT/2)/r gives us PT=2*r*cos 30°, leading to PT=2*4*(√3/2), resulting in PT=4√3 units.

Part b) results in
PT=4√3 units

Answer:

pt=8\sqrt{3

st=4

Step-by-step explanation:

Half of PT is 4√3.

ST is equivalent to r, which is 4.

Use the 30-60-90 triangle to find PT.

AnnZ [12381]
In the context of science, the rate is defined as a <span>metric that is evaluated in relation to another measured metric. To determine the rate for each set of data, we calculate the slope. The calculations proceed as follows:

Megan's growth rate = (12 - 4.5) / (4 - 1) = 2.5 inches weekly
Suzanne's growth rate = (11 - 5) / (4 - 1) = 0.5 inches weekly

If a geometric sequence has a1 = 256 and a8 = 512, find the exact value of the common ratio ????.
lawyer [12517]

Answer:r=1.104

Step-by-step explanation:

Starting value a_1=256

Also

can be expressed as

a_8=512

where r=common ratioa_8

a_8=ar^7

512=256r^7

2=r^7

r=\left ( 2\right )^{\frac{1}{7}}

r=1.104

Suppose log subscript a x equals 3, log subscript a y equals 7, and log subscript a z equals short dash 2. Find the value of the
AnnZ [12381]

Answer:

24

Step-by-step explanation:

Based on the logarithmic expressions given log_ax = 3, log_ay = 7, log_az = -2, we need to identify the value of log_a(\frac{x^3y}{z^4} )

from\ log_ax = 3, x = a^3\\\\from\ log_ay = 7,y = a^7\\\\from\ log_az = -2, z = a^{-2}By substituting x = a³, y = a⁷, and z = a⁻² into the logarithmic function log_a(\frac{x^3y}{z^4} ), we will derive;

= log_a(\frac{x^3y}{z^4} )\\\\= log_a(\dfrac{(a^3)^3*a^7}{(a^{-2})^4} )\\\\= log_a(\dfrac{a^9*a^7}{a^{-8}} )\\\\= log_a\dfrac{a^{16}}{a^{-8}} \\\\= log_aa^{16+8}\\\\= log_aa^{24}\\\\= 24log_aa\\\\= 24* 1\\\\= 24

Therefore, the result of the logarithmic expression is 24
