Solve 8 = 2x + 4.
Helppppppp
Answer:
x = -1
Step-by-step explanation:
8 = 2^(x + 4)
Rewriting 8 as 2^3
2^3 = 2^(x + 4)
Since the bases are the same, the exponents must be the same
3 = x+4
Subtract 4 from each side
3-4 =x+4-4
-1 =x
Answer:
This is the answer :
x=–1

Step-by-step explanation:
We need to find a midpoint. A midpoint splits the two end coordinates to meet at a point.
Use midpoint formula
[tex] \frac{ - 2 + 10}{2} = 4[/tex]
[tex] \frac{ - 11 + 1}{2} = - 5[/tex]
So the coordinates will be at

Evaluate the work below
Answer:
[tex]3 \sqrt{2} [/tex]
Step-by-step explanation:
Given
[tex] \frac{ \sin(60) \sec(60) \cot(30) }{ \cos( 45) ) } [/tex]
Using the unit circle, we know that
[tex] \sin(60) = \frac{ \sqrt{3} }{2} [/tex]
[tex] \cos(45) = \frac{ \sqrt{2} }{2} [/tex]
We can find sec and cot by using reciprocal identies.
[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]
[tex] \cos(60) = \frac{1}{2} [/tex]
So
[tex] \sec(60) = 2[/tex]
[tex] cot(x) = \frac{1}{ \tan(x) } [/tex]
[tex] \tan(30) = \frac{1}{ \sqrt{3} } [/tex]
so
[tex] \cot(30) = \sqrt{3} [/tex]
Plug in the values.
[tex] \frac{ \frac{ \sqrt{3} }{2} \times 2 \times \sqrt{3} }{ \frac{ \sqrt{2} }{2} } [/tex]
[tex] \frac{ \frac{ \sqrt{3} }{2} \times \frac{ \sqrt{12} }{1} }{ \frac{ \sqrt{2} }{2} } [/tex]
[tex] \frac{3}{ \frac{ \sqrt{2} }{2} } [/tex]
[tex]3 \sqrt{2} [/tex]
Keith is looking at a cliff. He determines that the angle of elevation to the top is 70° from where he is at. 70m away from Keith, Alan estimates the angle between the base of the cliff, himself, and Keith to be 29° while Keith estimates the angle between the base of the cliff, himself, and Alan to be 48°. What is the height, h, of the cliff to the nearest tenth of a metre?
1) 78.8m
2) 83.9m
3) 89.0m
4) 95.7m
This question completely baffled me on my homework, I still haven't done it because I don't even know how to approach it (Since it's a 3D problem)
Please help me out
Also, this homework is due in an hour so I'm starting to sweat
9514 1404 393
Answer:
4) 95.7 m
Step-by-step explanation:
The angle at the cliff base between Alan and Keith is ...
B = 180° -29° -48° = 103°
The law of sines will tell you the distance KB from Keith to the cliff base is
KB/sin(A) = KA/sin(B)
KB = KA×sin(A)/sin(B) = (70 m)sin(29°)/sin(103°) ≈ 34.82935 m
The height of the cliff is found from the tangent relation ...
Tan = Opposite/Adjacent
tan(70°) = height/(34.83 m)
height = (34.83 m)tan(70°) = 95.693 m
The height of the cliff is about 95.7 m.
_____
Additional comment
These problems can usually be resolved into two 2-D problems. Here, we can work out the distance we need from Keith to the cliff by considering only the ground plan of the site. Then we can work out the height of the cliff only considering the vertical plane containing Keith and the base of the cliff.
The attachment shows the ground plan triangle KAB.

What is the perimeter of the quadrilateral ABCD?
Given:
The figure of a quadrilateral ABCD.
To find:
The perimeter of the quadrilateral ABCD.
Solution:
In an isosceles triangle, the two sides and base angles are congruent.
In triangle ABD,
[tex]\angle DAB\cong \angle ABD[/tex] [Given]
[tex]\Delta ABD[/tex] is an isosceles triangle [Base angle property]
[tex]AD=BD[/tex] [By definition of isosceles triangles]
[tex]8=BD[/tex] ...(i)
In triangle BCD,
[tex]\angle BCD\cong \angle CDB\cong \angle CBD[/tex] [Given]
All interior angles of the triangle BCD are congruent, so the triangle BCD is an equilateral triangle and all sides of the triangle area equal.
[tex]BC=CD=BD[/tex]
[tex]BC=CD=8[/tex] [Using (i)] ...(ii)
Now, the perimeter of quadrilateral ABCD is:
[tex]Perimeter=AB+BC+CD+AD[/tex]
[tex]Perimeter=11+8+8+8[/tex]
[tex]Perimeter=35[/tex]
Therefore, the perimeter of the quadrilateral ABCD is 35 units.
By what percent will a fraction increase if its numerator is decreased by 60% and its denominator is decreased by 20%?
9514 1404 393
Answer:
-50%
Step-by-step explanation:
Suppose the fraction is f = p/q before any changes.
Decreasing the numerator by 60% multiplies it by (1 -0.60) = 0.4.
Decreasing the denominator by 20% multiplies it by (1 -0.20) = 0.8.
Then the new fraction is ...
f' = p(0.4)/(q(0.8)) = (p/q)(0.4/0.8) = f(0.5) = f(1 -0.50) = f(1 +(-50%))
The increase in the value of the fraction is -50%.

Answer:
17x + 2 = 16x+6
17x-16x= 6-2
x=4
Answer:
5.21212121
Step-by-step explanation:
The first thing to keep in mind is that a line is equal to 180. The first thing you sould start off by doing is write 17x+2+16x+6. Then to make it easier combine the like terms. Both combine 17x + 16x to get 33x, and 6 and 2 to get 8. Now the problem should be 33x + 8 = 180. Next we will take away 8 from both sides. This should eliminate 8 for us and give us 33x=180 as our next problem. Finally you will do the opposite of multiplying which is diving. 33 divided by itself gives us 0. So we will divide 172 by 33 to get 5.21212121.

What is the total distance that two people travel in 2 h if one of them is riding a bike at 20 mi/h and the other is walking at 3 mi/h?
Answer:
46 miles
Step-by-step explanation:
First, find the distance traveled by the person riding at 20 mph.
Multiply 20 by 2:
20(2)
= 40 miles
Find the distance traveled by the person riding at 3 mph.
Multiply 3 by 2:
3(2)
= 6 miles
Add these distances together:
40 + 6
= 46
So, the total distance is 46 miles
Answer:
46 miles
Step-by-step explanation:
Assuming both travel at a constant rate of miles per hour.
Time allowed: 2 hours.
Biker: 20 miles/hr, or (20 x 2) miles/ (2 x 1) hrs. = 40 miles/ 2 hours
Walker: 3 miles/hr or (3 x 2) miles/(2 x 1) hrs. = 6 miles/2 hours.
You are finding the total distance traveled together, and so add the two miles together:
40 + 6 = 46
46 miles in 2 hours is your answer.

Pls Help I'm really really stumped.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The graph shown with your problem statement does not pass the vertical line test, so is not the graph of a function. (A vertical line intersects the graph in more than one place.) This graph can be rejected immediately.
I find it convenient to look at the domain statements (x≤1 and x>1). This tells you that you can separately evaluate the graph to the left of x=1 and to the right of x=1. Each of those portions of the graph must match the corresponding expression.
Here, it looks sufficient to identify the slope of the line in each domain. (We don't know what graphs you're selecting from, so we don't know what you will need to look at to differentiate the correct one from the rest.)
For x < 1, the coefficient of x is 3, so the line will have a steep upward slope.
For x > 1, the coefficient of x is -2, so the line will have a slightly less steep downward slope.
The value of z(1) is 3(1)-2=1, so (1, 1) is at the top end of the line forming the left side of the graph. The limit as x approaches 1 from the right is -2(1)+3=1. This means the two lines meet at the point (1, 1) and the graph has a generally ∧ shape. The attachment shows the graph you're looking for.

5b. Which has more different ways :
Choosing two out of five OR
choosing three our of five?
Answer:
a) 10 salads
b) 5 Choose 2 and 5 Choose 3 result in the same amount
Step-by-step explanation:

Co-interior angles or same side interior angles lie between two lines and on the same side of a transversal. In each diagram the two marked angles are called co-interior angles. If the two lines are parallel, then co-interior angles add to give 180o and so are supplementary.

What number must you add to complete the square? x^2+26x=23
Answer:
169
Step-by-step explanation:
x²+26x=23
=> to complete the square, the equation should be : x²+26x + (26/2)² = 23 + (26/2)²
<=> x² +26x + 13² = 23 + 13²
<=> x² +26x +169 = 23 + 169
<=> (x+13)² = 192
so, (x+13)² is the square form , and 169 must be added to complete the square
For 2ab to complete in (a+b)² formula
2ab=26a=1
2b=26b=13b²=169So 169 must be added
Find the angle of depression
from point A to point C.
?
66°
5 mi
B
Angle of depression = [ ? ]
Given:
In triangle ABC, [tex]m\angle A=66^\circ, AB=5\text{ mi}[/tex].
To find:
The angle of depression from point A to point C.
Solution:
According to angle sum property, the sum of all interior angles of a triangle is 180 degrees.
In triangle ABC,
[tex]m\angle A+m\angle B+m\angle C=180^\circ[/tex]
[tex]66^\circ+90^\circ+m\angle C=180^\circ[/tex]
[tex]156^\circ+m\angle C=180^\circ[/tex]
[tex]m\angle C=180^\circ-156^\circ[/tex]
[tex]m\angle C=24^\circ[/tex]
We know that if a transversal line intersect the two parallel lines, then alternate interior angles are equal. So, the angle of depression from point A to point C is equal to the measure of angle C in triangle ABC.
Therefore, the angle of depression is 24 degrees.
