What is tan angle QTR if line PR is tangent to circle T at Q, and TS = 1 cm?

1 answer:

3 0

Tangent = opposite / adjacent

In the diagram:
TQ is the short leg or the opposite
QR is the long leg or the adjacent
TR is the hypotenuse. TS is part of the hypotenuse.

Tan(QTR) = TQ / QR

TS = 1 ; TQ = TS so, TQ = 1

Tan(QTR) = 1/QR

I think the answer is C.RQ

Answer:

see explanation

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ 4, 7 ], thus

z = $\frac{g(7)-g(4)}{7-4}$

Complete the following statement. The number of iPhones sold today at an Apple store is an example of ________ data.

faltersainse [42]

Answer: Option 'e' is correct.

Step-by-step explanation:

Since we know that

Discrete data are those data which is countable and it is expressed in exact numerical form.

Continuous data are those data which is lie within the interval and it varies so it does not expressed in exact numerical form.

Here, the number of iphones sold today at an Apple store is countable and it can be expressed in exact numbers.

So, it is considered as discrete.

Hence, Option 'e' is correct.

which of the following is true regarding the solutions to the logarithmic equation below 2log ^6(x)=2 log ^6 (x^2 )=2 x^2=36 x=6

nekit [7.7K]

Answer:

Step-by-step explanation:

I'm assuming these are logs to the base 6

2 log6 x = 2

log6 x^2 = 2

So x^2 = 6^2

x = 6, -6.

In the standard (x, y) coordinate plane, what is the y-intercept of the line given by the equation <img src="https://tex.z-dn.ne

Agata [3.3K]

the y-intercept will be $\frac{8}{5}$

the standard line equation is y = mx + b, where y is the y point, x is the x point, m is the slope, and b is the y-intercept.

to get the y intercept, we need to transform into the line equation, and caculate out b.

3x + 5y = 8
so 5y = 8 -3x
then y = $\frac{8}{5}$ - $\frac{3}{5}$ x
which means that $\frac{8}{5}$ = the y intercept.
