Answer:
6√2
Step-by-step explanation:
This is a right triangle. The legs of a right triangle are the sides that make up the right angle, and the hypotenuse is the side opposite to the right angle. To find x, we will use the Pythagorean Theorem. This states that a² + b² = c², where a and b are the legs and c is the hypotenuse. Since we know that the legs are both x and the hypotenuse is 12, we can plug these values into our equation to get x² + x² = 12².
2x²=144 → x² = 72 → x = √72, which simplifies to x = 6√2. Hope this made sense and helps!

Find the minimum value of the parabola y =X^2 + 5x – 3
Answers
Answer:
Minimum value = −13/4
Step-by-step explanation:
Answer:
-37/4
Step-by-step explanation:
The minimum value of the parabola y =x² + 5x – 3 is f(-b/2a)
in this case a = 1 and b = 5 and c = -3
then
-b/2a = -5/2(1) = -5/2
then
f(-b/2a) = f(-5/2) = -37/4

B. 7/π radians
C. 7/4 radians
D. 7 π/4 radians
Answers
Answer:
[tex]\theta=\dfrac{7}{4}\ \text{radian}[/tex]
Step-by-step explanation:
We have,
Radius of the circle is 12 cm
Arc length, l = 21 cm
It is required to find the central angle of the circle. The formula for the length of an arc of a circle is :
[tex]l=r\times \theta[/tex]
[tex]\theta[/tex] is central angle
[tex]\theta=\dfrac{l}{r}\\\\\theta=\dfrac{21}{12}\\\\\theta=\dfrac{7}{4}\ \text{radian}[/tex]
So, the angle at the centre of the circle is [tex]\dfrac{7}{4}\ \text{radian}[/tex].

Answers
Answer:
10
Step-by-step explanation:
13x + 5x = 180
18x = 180
x = 10
180 divided by 18 = 10 so the answer is 10. To check my work I multiplied 5x10 which is 50 and 13x10 which is 130 and they add up to 180 degrees.
x is equal to 10.

-6x-x^2-8
Answers
Answer:
x = -3 +/- sqrt(17)
Step-by-step explanation:
-6x - (x^2) - 8 = 0
-((x^2) + 6x + 8) = 0
(x^2) + 6x + 8 = 0
(x + 3)^2 - 1 = 0
(x + 3)^2 = 1
x + 3 = +/- sqrt(1)
x + 3 = +/- 1
x = -3 +/- 1

Does anyone know what x is?
Answers
Answer:
x = 4
Step-by-step explanation:
-3x + 4 = -8
-3x = -8 - 4
-3x = -12
x = -12/-3
x = 4
Answer: x = 4
Step-by-step explanation: Move all terms that don't contain x to the right side and solve.
-3x +4 = -8
-4 -4
Subtract four from the four to cancel out and the -8.
That makes the equation -3x = -12
Then, divide by -3 by -3, then -12 divide by -3, to equal 4

Answer:
x = 11
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FEB and ∠ DEB are adjacent angles and supplementary, thus
∠ FEB = 180 - 4x , so
180 - 4x + x = 147, that is
180 - 3x = 147 ( subtract 180 from both sides )
- 3x = - 33 ( divide both sides by - 3 )
x = 11

1. Anike needs a new pair of athletic shoes for her soccer tryouts. The regular price for the shoes is $129.00. There is a sales tax of 7%. Anike has a budget of $150.00. How much money will Anike have left after this purchase? Round to the nearest cent, like $7.15.
50−(129+129(0.07))=$11.97
129+129(0.07)=$138.03

Answers
Answer:
$150-$129-($129*7%)=$11.97
$531.25
$9414.5
Step-by-step explanation:
The amount that Anike would have left is the budgeted amount minus the regular price as well as the applicable sales tax.
Amount left=$150-$129-($129*7%)=$11.97
The amount that Harper would have to pay is the purchase price of $500 plus the 6.25% of sales price as sales tax i.e $500+$500*6.25%=$531.25
The yearly tax fees is the appraised value multiplied by property tax rate i.e $250,000*3.7658%=$9414.5
The property tax rate is 3.7658% not 37.658%

B.) 5,640,000
C.) 7,893,600
D.) 11,881,376
Answers
Answer:
7,893,600
Step-by-step explanation:
Permutations
n = possible things used (26 letters)
r = how many at a time (5 at a time - this is without repeating)
nPr = n! / (n - r)!
26P5 = 26! / (26 - 5)!
26! = 26 x 25 x 24 x 23 x 22... = 403291461126605635584000000
(26 - 5)! = 21! = 51090942171709440000
An easy hack for solving division of large factorials is to use canceling.
26!/21! = 26 x 25 x 24 x 23 x 22 (because 21 down to 1 is cancelled by 21!)
= 7,893,600

In a certain country, the car license plate formed by 4 numbers from the digits 1-9 followed by 3 letters from the alphabet. How many license plates can be formed if neither the digits nor the letters are repeated?
Answers
Answer:
78,624,000 license plates
Step-by-step explanation:
For each of the 4 numbers, we have the following possibilities:
First number: 10 digits possible
Second number: 9 digits possible (one used)
Third number: 8 digits possible (two used)
Fourth number: 7 digits possible (three used)
For each of the 3 letters, we have the following possibilities:
First letter: 26 digits possible
Second letter: 25 digits possible (one used)
Third letter: 24 digits possible (two used)
The total number of license plates is the product of all these possibilities:
Number of plates = 10 * 9 * 8 * 7 * 26 * 25 * 24 = 78,624,000 license plates
The license plates can be formed if neither the digits nor the letters are repeated is 78,624,000.
What are permutation and combination?A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

10x^2+15x+5??? Rewrite the question by completing the square factor
Answers
Answer:
5 • (2x + 1) • (x + 1)
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
((2•5x2) + 15x) + 5
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
10x2 + 15x + 5 = 5 • (2x2 + 3x + 1)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 + 3x + 1
The first term is, 2x2 its coefficient is 2 .
The middle term is, +3x its coefficient is 3 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 2 • 1 = 2
Step-2 : Find two factors of 2 whose sum equals the coefficient of the middle term, which is 3 .
-2 + -1 = -3
-1 + -2 = -3
1 + 2 = 3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 2
2x2 + 1x + 2x + 1
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x+1)
Add up the last 2 terms, pulling out common factors :
1 • (2x+1)
Step-5 : Add up the four terms of step 4 :
(x+1) • (2x+1)
Which is the desired factorization
So the answer is:
5 • (2x + 1) • (x + 1)
