Look at the figure below: an image of a right triangle is shown with an angle labeled y degrees If sin y° = s divided by 8 and t

an y° = s divided by t, what is the value of cos y°?
cos y° = 8s
cos y° = 8t
cos y°= t / 8
cos y°=8 / t

Answer:

Cos y = t / 8

Step-by-step explanation:

Using the hints given in the question, the omitted tribagke will look like the triangle attached on the picture ;

From trigonometry :

Sin y = opposite / hypotenus

Sin y = s / 8

Opposite side = s ; hypotenus = 8

Tan y = opposite / Adjacent

Tan y = s / t

Adjacent side = t

Then ;

Cos y = Adjacent / hypotenus

Hence,

Cos y = t / 8

Simplify the expression: show all ur steps/ wrk PLEASE,1+2x3-18/3+(5(2+2)]

Maurinko [17]

Ok let's do this*pops knuckles*

let's add the first side

$1 + 2 \times 3 - 18$
order of operations demands that we do multiplication first(P.E.M.D.A.S)

so
$2 \times 3 = 6$
now we can add the 1 from
$1 + (6) - 18$
into our six

$6 + 1 = 7$
now we substract

$(7) - 18 = - 11$
now we have
$- 11 \div 3 + (5(2 + 2))$
now we focus on the
other side
$3 + (5(2 + 2))$
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.
$(5(2 + 2)) = (((5 \times 2) + (5 \times 2) = 20$
now we have
$3 + 20 = 23$

(the three is from the original equation)

now we plug in our final numbers

$- 11 \div 23$
or
$\frac{ - 11}{23}$
I hope this helps

Given f(x) = X^2 – 5x + 6 state axis of symmtry

Setler79 [48]

Solve this by factorising like this:
F(x)= x^2-5x+6
= (x-2)(x-5)
X= 2 or x= 5
So the axis of symmetry is 3.5 ( got this by dividing 2 and 5 in the middle on the number line or you can call it cetacean plane

Let T: set of real numbers R Superscript nℝnright arrow→set of real numbers R Superscript mℝm be a linear transformation, and

Klio2033 [76]

Answer:

$\{T(v_1), T(v_2), T(v_3)\}$ is linearly dependent set.

Step-by-step explanation:

Given: $\{v_1,v_2,v_3\}$ is a linearly dependent set in set of real numbers R

To show: the set $\{T(v_1), T(v_2), T(v_3)\}$ is linearly dependent.

Solution:

If $\{v_1,v_2,v_3,...,v_n\}$ is a set of linearly dependent vectors then there exists atleast one $k_i:i=1,2,3,...,n$ such that $k_1v_1+k_2v_2+k_3v_3+...+k_nv_n=0$

Consider $k_1T(v_1)+k_2T(v_2)+k_3T(v_3)=0$

A linear transformation T: U→V satisfies the following properties:

1. $T(u_1+u_2)=T(u_1)+T(u_2)$

2. $T(au)=aT(u)$

Here, $u,u_1,u_2$ ∈ U

As T is a linear transformation,

$k_1T(v_1)+k_2T(v_2)+k_3T(v_3)=0\\T(k_1v_1)+T(k_2v_2)+T(k_3v_3)=0\\T(k_1v_1+k_2v_2+k_3v_3)=0\\$

As $\{v_1,v_2,v_3\}$ is a linearly dependent set,

$k_1v_1+k_2v_2+k_3v_3=0$ for some $k_i\neq 0:i=1,2,3$

So, for some $k_i\neq 0:i=1,2,3$

$k_1T(v_1)+k_2T(v_2)+k_3T(v_3)=0$

Therefore, set $\{T(v_1), T(v_2), T(v_3)\}$ is linearly dependent.

A feature film runs 2 h 12 min. The theater requires 12 min between performances, and has 12 min of previews and short subjects

GenaCL600 [577]

1:00 ? because it <em>says </em>that there is a needed 12 minuted between the films plus another 12 minutes of previews which equals 24.... sooo 24 plus 36 should equal 60 which is an hour so the answer as far as i know is 1:00.... Hope this helped :)
