Can somebody help please and thank you!!

Answer:

A=31.64 B= 18.34 C= 130.20

Step-by-step explanation:

calculating for A using cosine rule

50^2= 30^2+73^2-2×30×73CosA

2500= 900+5329-4380COSA

2500= 6329-4380COSA

2500-6329= -4380COSA

-3729= -4380COSA

COA= -3729/-4380

COSA= 0.8514

A=COS^-1(0.8514)

A= 31.64

calculating B using sinerule

sin 31.64/50= sinB/30

sinB = sin31.64×30/50

sinB = 0.3147

B = 18.34

calculating for C

31.46+18.34+C= 180

C= 180-49.8

C=130.20

A=32.2

C=20.11

The equation of the tangent line to the given curve (which is parallel to line (2x−y+9=0) is y−2x−3=0.

There are two important elements to finding an equation that defines a tangent line: its slope and its point of contact with a curve.

The equation of the given curve is;

[tex]\rm y=x^2-2x+7[/tex]

On differentiating with respect to x, we get:

dx/dy=2x−2

The equation of the line is;

2x−y+9=0

y=2x+9

The slope of the line =2

If a tangent is parallel to line 2x−y+9=0, then the slope of the tangent is equal to the slope of the line.

Therefore, we have:

2=2x−2

2x=4

x=2

Now, at x=2

y=22−2×2+7=7

Thus, the equation of the tangent passing through (2,7) is given by,

y−7=2(x−2)

y−2x−3=0

Hence, the equation of the tangent line to the given curve (which is parallel to line (2x−y+9=0) is y−2x−3=0.

Answer:

the multiplication of rational numbers is distributive over addition of rational numbers.

Answer:

maybe        3

Step-by-step explanation:

Based on the current real and the full employment real GDP, Rayton's economy is at a Recession stage.

The current budget balance in Rayton is -$1,000. The budget can be balanced by reducing government spending or increasing taxes. Both of these would decrease real GDP.

The fact that the current real GDP is less than the full employment GDP shows that the nation is at a recession stage where it is underperforming.

This can be found as:

= Government revenue(taxes) - government spending

= 3,000 - 1,000 - 3,000

= -$4,000

In order to make a balanced budget where government revenue will equal government spending, the government either needs to reduce spending or increase revenue ( taxes ).

Increasing taxes or reducing spending, will lead to less money available for spending in the economy which will lead to a decrease in real GDP.

Answer:

The green figure, #4

Answer:

Scale factor of 1/2.

Step-by-step explanation:

Note that the comparison is figure A to figure B'.

The original measurements that are given are the side measurements of 16 & 6. In comparison to the corresponding parts for the other figure, it would be 8 & 3 respectfully.

Find the factor in which they change by multiplying.

16x = 8

6x = 3

Isolate the variable by dividing:

(16x)/16 = (8)/16

x = 8/16 = 1/2

(6x)/6 = (3)/6

x = 3/6 = 1/2

The scale factor is 1/2.

LETS DO THIS!

Step-by-step explanation:

when a line is perpendicular the line is negative and reciprocal.y

y=2x+6

now we substitute.

-4=2(5)+b

-4=10+b

-14=b is your answer

Step-by-step explanation:

Hlew frnd!

To find the slope of the perpendicular line we just take the reciprocal and therefore change the sign of slope,

Perpendicular to y = -½x + 6

Hence, the slope will be = -½ = 2

Now we have to find the slope-intercept form, So

here y intercept is given and the point will be (0,b) then eqs. of line,

=> y = mx + b [slope-intercept form]

=> -4 = 2*5 + b

=> -4 = 10 + b

=> b = -14

Here x is the angle of the elevation and the value of x is 31 degrees.

We have given that,

Amari is observing a woodpecker near the top of a tree,

as shown in the diagram given.

We have to determine,

The measure of angle x, the angle of elevation, is rounded to the nearest degree.

[tex]tan(\theta)=\frac{Opposite \ side}{Hypotenuse}[/tex]

From the diagram,

Opposite side=20ft

Adjacent side=36ft

Use this value of the above formula.

So we get,

[tex]tan(\theta)=\frac{20}{36} \\\\tan(x)=5/9\\\\tan(x)=0.55\\x=tan^{-1}(0.55)\\x=31.51^0[/tex]

Here x is the angle of the elevation and the value of x is 31 degrees.

Therefore the value of x is 31.
