Answer:

Step-by-step explanation:

Triangle GEF is a right angle triangle.

From the given right angle triangle

GE represents the hypotenuse of the right angle triangle.

With ∠E as the reference angle,

FE represents the adjacent side of the right angle triangle.

FG represents the opposite side of the right angle triangle.

To determine tan E, we would apply the tangent trigonometric ratio

Tan θ = opposite side/adjacent side. Therefore,

Tan E = 56/33

Tan E = 1.69697

It becomes 1.70 to the nearest hundredth.

Find<br>a,b<br>such<br>that 7.2, a, b, 3 are in A.P.

Answer:

The value of a = 5.8

The value of b = 4.4

Step-by-step explanation:

Given

7.2, a, b, 3 are in A.P

$2a = 7.2+b$

$b = 2a - 7.2$

a, b, 3 are also in A.P

$2b\:=\:a\:+\:3$

Putting $b = 2a - 7.2$

$2\left(2a-7.2\right)=a+3$

$4a-14.4=a+3$

$\mathrm{Add\:}14.4\mathrm{\:to\:both\:sides}$

$4a-14.4+14.4=a+3+14.4$

$4a=a+17.4$

$4a-a=a+17.4-a$

$3a=17.4$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3a}{3}=\frac{17.4}{3}$

$a=5.8$

Now, plugging $a=5.8$ in $b = 2a - 7.2$

$b=2\left(5.8\right)-7.2$

$b=2\cdot \:5.8-7.2$

$b=11.6-7.2$

$b=4.4$

Therefore,

The value of a = 5.8

The value of b = 4.4

I need help with this practice I am having a tough time solving it properly

Monica [59]

Given:

There are given that the parent functions as a cosine function:

Where,

The amplitude of the function is 9.

The vertical shift is 11 units down.

Explanation:

To find the cosine function, we need to see the standard form of the cosine function:

$f(x)=acos(bx+c)+d$

Where,

a is the amplitude of the function,

Now,

According to the question:

The amplitude of the function is 9, which means:

$f(x)=9cos(bx+c)+d$

The vertical shift is 11 units down, which means:

$f(x)=9cos(bx+c)-11$

For period:

$\begin{gathered} f(x)=-9cos(\frac{12\pi}{7}x+0)-11 \\ f(x)=-9cos(\frac{12\pi}{7}x)-11 \end{gathered}$

Final answer:

Hence, the cosine function is shown below;

$f(x)=-9cos(\frac{12\pi}{7}x)-11$

A system of equations is graphed on the coordinate plane. y=−2x−3y=−2x+2 Graphs of the equations y equals negative two x plus tw

AleksandrR [38]

In y = mx + b form, the slope will be in the m position and the y int will be in the b position

y = -2x + 2....slope = -2 and y int = 2
y = -2x - 3.....slope = -2 and y int = -3

when u have 2 lines that both have the same slope but different y intercepts, u have parallel lines with no solution because ur lines never intersect.

so ur answer is : no solutions or 0 solutions
