Step-by-step explanation:
Answer:
wrong subject, but I think it goes both ways. Fear is fundemental and is why we have survived so long, but fear can hurt you, because of phobias. I'm terrified of spiders, and some people are terrified of the outdoors. That can affect you in a big way.

Determine if the sequence is geometric. If it is, find the common ratio. ( -4, 12, -36, 108, ... )
Step-by-step explanation:
to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term
so, 12/-4 = -3
also, -36/12 = -3
here u see the ratio is always same, i.e., common ratio.
thus u can say it is a geometric series with common ratio -3

Answer:
Step-by-step explanation:
(-2,2) lies above the vertex, so the parabola opens upwards.
Vertex-form equation for an up-opening parabola with vertex (-5,-1):
y = a(x+5)² - 1, a>0
Plug in (-2,2) and solve for a:
2 = a(-2+5)² - 1
a = ⅓
Equation of parabola:
y = ⅓(x+5)² - 1
Brent leaves school to go home. He walks 10 blocks north and then 6 blocks west. If Brent could walk in a straight line to the school, what is the exact distance between Brent and school
Answer:
11.66 units
Step-by-step explanation:
Given that he walks 10 blocks north and then 6 blocks west..
When combined with the straight line to the school, this forms a right angled triangle with the straight line as the hypotenuse.
Hence, let the straight line be h
h^2 = 10^2 + 6^2 (using Pythagoras theorem)
h^2 = 100 + 36
h^2 = 136
h = √ 136
h = 11.66 units

Step-by-step explanation:
Fig 1

<D and <E are base angle of isosceles triangle.
Fig 2
AB=AC=BC=8
All the side of equilateral are equal and all interior angle also equal.
Answer:
Step-by-step explanation:
a) ΔFED is isosceles triangle. EF = ED
∠F = ∠D =x {Angles opposite to equal sides are equal}
∠F + ∠E + ∠D = 180 {Angle sum property }
x +x + 30 = 180
2x + 30 = 180
2x = 180 -30
2x = 150
x = 150/2
x = 75
∠F = 75
b) All the angles are equal. So, it is an equilateral triangle. In equilateral triangle all sides are equal.
So, AB = 8

Consider the rectangle. Which pair of expressions represents the perimeter of the rectangle?
PLEASE HELP!!!
Answer:
6x + 2 and 2x + (x + 1) + 2x + (x + 1)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = 2x
Width = x + 1
Perimeter of a rectangle = 2(length + width)
= 2{2x + (x + 1)}
= 2(2x + x + 1)
= 2(3x + 1)
= 6x + 2
Perimeter = length + width + length + width
= 2x + (x + 1) + 2x + (x + 1)
what is 5 times a number minus 3 is 12 ?
Answer:
5*x-3=12
the number is 3 because 5*3=15 and 15-3=12
Answer:
3
Step-by-step explanation:
x - 3 = 12
12 + 3 = 15
15 - 3 = 12
5( ? ) = 15
15/5
? = 3
5(3) = 15 - 3 = 12

1. Let x= -2 and y= -5. (NC.7.NS.2) Which expression has a negative value? A. X+y B.X-y C.[x] [y] D. X/y
Answer:
A. X + Y
Step-by-step explanation:
From this question x = -2 and y = -5
We are to find out the expression that would give a negative value.
X+Y
(-2)+(-5)
+(-) gives a negative sign. So we have
= -2-5
= -7
For x - y
(-2) - (-5)
-(-) = positive
= -2 + 5
= 3.
For [x][y]
= (-2) x (-5)
= 10
since a negative sign multiplied with another negative sign gives a positive result
For X/Y
= -2/-5
= 2/5 the result here is positive because 2 negative signs when divided cancel out.
Therefore the answer is option A since it's result is negative. Others are positive

A pirate in search of a treasure hikes three days in a row. He hikes 12.5 km to his destination on the first day, 18 km to his destination on the second day, and 14 km to his destination on the third day. He hikes 1 km/h slower on the first day than on the second day, and 1 km/h faster on the first day than on the third day. The third day's hike takes 30 minutes longer than the second day's hike. How long does the pirate search (across all three days) if he spends 2 hours digging for treasure at each destination?
Answer:
15hrs
Step-by-step explanation:
We can start by expressing the speed of the second trip as x. This means that the first trip must be x-1, and second (x-1)-1=x-2. Next we can form an equation with the information that the third day hike takes 30 min longer than second day hike. Since we now the distance of both days, we can express them in time. So... [tex]\frac{18}{x}+\frac{1}{2}=\frac{14}{x-2}[/tex] ... We can solve by finding a LCM of all three expressions. Doing so we get 2x(x-2). Now multiplying out with the new denominators, we get 36(x-2)+x(x-2)=28x. Solving as a quadratic equation, the solution comes out to be x=6, x=-12. But as speed can't be negative, only solution is x=6. Now we get the speed of each day's hike. First day=x-1=5, second day=6, third day =x-2=4. Finding the time is simple, just do distance/speed. First day=12.5/5=2.5hrs. Second day=18/6=3hrs. Third day=14/4=3.5hrs. Adding total hrs up... 2.5+3+3.5=9. Finally step is accounting for the 2hr digging time per day. 2hrs*3= 6hrs. 6hrs+9hrs=15hrs. Hope this helps!

The approximate volume of first cone is 709[tex]mi^{3}[/tex] and the volume of second cone is 262 [tex]cm^{3}[/tex].
What is volume?Volume is amount of substance a container can hold in its capacity. Volume of cone is basically 1/3 *π[tex]r^{2}h[/tex] in which r is radius and h is height of cone.
How to calculate volume?We have been given two cones. First is having radius of 7 mi and
height 14 mi and second is having radius of 5 cm and height of 10 cm. We are required to find out the volume of both the cones.
Volume of first cone=1/3 *π[tex]7^{2}* 14[/tex]
=(49*3.14*14)/3
=708.86
Approximately 709 [tex]mi^{3}[/tex]
Volume of second cone =1/3π[tex]5^{2} *10[/tex]
=(25*3.14*10)/3
=261.67
Approximately 262 [tex]cm^{3}[/tex].

Step-by-step explanation:
The diargram show a right show a right -angle and a parallelogram the area of the parallelogram is times the area of the traiangle and its perpendicular height is h cm find the value of h
Question:
The diagram shows a right -angle and a parallelogram. The area of the parallelogram is 5 times the area of the triangle. The perpendicular height of the parallelogram is h. Find h
Answer:
[tex]h =12cm[/tex]
Step-by-step explanation:
Given
Triangle
[tex]Base = 9cm[/tex]
[tex]Height = 16cm[/tex]
Parallelogram
[tex]Base = 30cm[/tex]
[tex]Height = h[/tex]
Calculate the area of the triangle
[tex]Area = 0.5 * Base * Height[/tex]
[tex]Area = 0.5 * 9cm * 16cm[/tex]
[tex]Area = 72cm^2[/tex]
When multiplied by 5, gives the area of the parallelogram.
So:
The area of Parallelogram is:
[tex]Area = Base * Height[/tex]
[tex]Area = 30cm * h[/tex]
This gives:
[tex]30cm * h = 72cm^2 * 5[/tex]
Make h the subject
[tex]h = \frac{72cm^2 * 5}{30cm}[/tex]
[tex]h = \frac{72cm^2}{6cm}[/tex]
[tex]h =12cm[/tex]
