Please answer area of this triangle
Answers
Answer:
[tex]A=2\text{ units}^2[/tex]
Step-by-step explanation:
The area for a triangle is given by:
[tex]A=\frac{1}{2}bh[/tex]
Where b is the base length and h is the height.
The base is 2 and height is also 2. Therefore:
[tex]A=\frac{1}{2}(2)(2)[/tex]
Simplify:
[tex]A=\frac{1}{2}(4)[/tex]
Multiply:
[tex]A=2\text{ units}^2[/tex]
NEED HELP ASAP!!!!!!!!!!
Answers
Answer:
In order from smallest to largest:
g(x)=(1,-2)
now, f(x) and h(x) would reach the same height, so from left to right on the graph, if plotting all vertices:
h(x)=(-2,2)
f(x)=(4,2)
Step-by-step explanation:
f(x)
f(x)=-2(x-4)^2+2
This is the vertex form of a quadratic equation: The formula used is f(x)=a(x-h)^2+k, where (h,k) is the vertex. In this case, 4 is h and 2 is k, so the vertex of this equation is (4,2).
g(x)
g(x)=5x^2-10x+7
To find the vertex of a quadratic equation in standard form, you first have to find the x-coordinate of the vertex using the formula, -b/2a. In this equation, a=5 and b=-10, so plug into the formula: -(-10)/2(5)=10/10=1, so the x-coordinate of the vertex is 1. Now to find the y-coordinate of the vertex by plugging in the x-coodinate for x in the equation: 5(1)^2-10(1)+7=5(1)-10+7=5-10+7=-5+7=-2, so your y-coordinate is -2. Therefore, your vertex for this equation is (1,-2).
h(x)
So, this quadratic function is in the form of a graph. The vertex of the graph is the maximum of minimum value of the graph, depending on whether the graph is positive or negative. In this graph, it is the maximum point, which is (-2,2).
Diameter of Earth is 12756000m. In 1996, a new planet was discovered whose diameter is 5/86 of the diameter of Earth. Find the diameter of this planet in km.
Answers
Answer:
741.63km
Step-by-step explanation:
From the above question, we know the following things:
Diameter of the Earth = 12756000m
Diameter of the new planet = 5/86 of the Diameter of the Earth
Diameter of the new planet =
5/86 × 12756000m
= 741627.90698m
The diameter of the new planet = 741627.90698m
We were asked to find the diameter of the new planet in km, hence we convert from meters to kilometers
1m = 0.001km
741627.90698m =
741627.90698 × 0.001km
= 741.62790698km
Approximately = 741.63km
Therefore, the diameter of the new planet = 741.63km
Angie and kenny play online video games. Angie biys 1 software package and 4 months of game play. Kenny buys 1 software package and 1 month of game play. Each software costs $35. If their total cost is $130 what is thr cost of one month of game play
Answers
Answer:
1 month of game play will cost $12
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of one month of game play.
From the question, we know the following;
Angie bought 1 software package and 4 months of game play
while
Kenny bought 1 software package and 1 month of game play.
The total packages and months bought will be;
2 packages and 5 months of game play
From the question, we are told that 1 month of game play is $35, so 2 months of game play will be 2 * $35 = $70
So the amount remaining for the 5 months will be; $130 - $70 = $60
So if 5 months cost $60, it means one month will be $60/5 = $12

Find the approximate side length of a square game board with an area of 105in2.
Answers
Answer:
Approximately 10.2 inches
Step-by-step explanation:
The area of a square is given by the formula:
[tex]A=s^2[/tex]
Where A is the area and s is the side length.
Since we already know that the area A is 105, substitute:
[tex]105=s^2[/tex]
Now, take the square root of both sides:
[tex]s=\sqrt{105}[/tex]
Use a calculator:
[tex]s\approx10.2470[/tex]
So, the side length is approximately 10.2 inches.

Find the product of (x + (3+5i))^2
Answers
Answer:
x^2 +6x +10xi -16 +30i
Step-by-step explanation:
(x + (3+5i))^2
Rewriting as
(x + (3+5i)) (x + (3+5i))
Let 3+5i = m
(x + m) (x + m)
FOILing
x^2 + xm+xm+m^2
x^2 +2xm + m^2
Replacing m with 3+5i
x^2 +2x (3+5i) +(3+5i)^2
Distribute
x^2 +6x +10xi +(3+5i)^2
Now FOIL (3+5i)^2
( 3+5i) ( 3+5i)
3*3+ 3*5i + 3*5i+ 25i^2
= 9 +15i+15i +25(-1)
9+30i -25
-16 +30 i
Replacing that in the equation
x^2 +6x +10xi -16 +30i
Answer:
x² + 6x + 10xi -16 + 30i
Step-by-step explanation:
(x + (3 + 5i) )²
use the binomial theorem:
(a + b)² = a² + 2ab + b² to expand (x + (3 + 5i) )²
substitute the values,
x² + (6 + 10i)x + (-16 + 30i)
therefore
x² + 6x + 10xi -16 + 30i

1. Point P is between points F and G. The distance between points F and P
is 1/4 of FG. What is the coordinate of point P?
Answers
Answer:
Point P is in between points F and G.
Now, here we do not have the actual locations of F and G, so i will answer this in a general way.
Suppose that F is located at 0 and G is located at some value A.
Then the distance FG = A - 0 = A.
Now, the distance between F and P is:
Distance = (1/4)*FG = A/4
Then the location of P is equal to the location of F plus A/4
P = 0 + A/4
Now, writing this in a more general way:
P = F + FG/4
The state of Kansas has a population of about 2.85 million people. Find the population density
in the people per square mile.
Answers
Answer:
In the state of Kansas, the density of people per square mile is 34.3
Step-by-step explanation:
According to US topographers, the state of Kansas has an area of 213 096 km².
If 1 km² is equal to 0.39 mi², then how much is 213 096 km².
If 1 km² : 0.39 mi².
213,096 km² : 83,107.44 mi²
If the state of Kansas has a population of 2.85 million people, then:
2.85 x10^6 people / 83 107.44 mi² =
34.3 people per square mile.

C. Lamb and mutton produce more protein per square meters than pig meat and poultry
D. Nuts and grains produce less protein per square meter than milk and cheese
Answers
Answer:
the answer is correct 2 one
Answer:
A. Beef uses significantly more land than plants to produce 100 grams of protein
Step-by-step explanation:
Let's examine each answer choice.
A. Beef uses significantly more land than plants to produce 100 grams of protein
This is true. Beef uses 163.6 square meters of land, while peas only use 3.4 square meters.
B. Meat production is more efficient than farming protein from fish and prawns
This is not true. Meat production is less efficient, because it uses more land than fish and prawns.
C. Lamb and mutton produce more protein per square meters than pig meat and poultry
This is false. Lamb produces less protein per square meter, because it takes 184.8 square meters to produce 100 grams of protein, while pig meat only takes 10.7 square meters to make the same amount.
D. Nuts and grains produce less protein per square meter than milk and cheese
This is false. Milk and cheese require more square meters per 100 grams of protein/ Therefore they produce less protein per square meter, not the nuts and grains.
So, the best answer choice is A. Beef uses significantly more land than plants to produce 100 grams of protein

A pair of shoes cost $120 but they are 25% Off;
What would be discount and the final price of those

Answers
Answer:
Discount = $30, Final price = $90
Step-by-step explanation:
25% is one quarter. 120/4=30
One quarter of 120 is 30, so - 30 would give discounted price of $90.
Similarly you could think of it like the discounted price is 75% of the original one and do 120x0.75=90 to find 75% of 120.

If you vertically compress the absolute value patent function, f(x)=|x|, by a factor of 5, what is the equation of the new function?
Answers
A vertical compression implies a reduction in the y-values of the absolute value function. Therefore, the term that we use to accomplish the reduction cannot be attached to the x in the equation. If so, we would end up with a horizontal stretch, not a vertical compression.
Compression implies a reduction, or dividing, so our term will be 1/5. This should be placed outside of the absolute value bars so that the compression affects only the y-values.
Correct answer: B. g(x) = 1/5|x|
