Answer:
−x2+2x−1=0
Step-by-step explanation:
To write an equation in standard form, move each term to the left side of the equation and simplify.
ax2+bx+c=0
Move 1
to the left side of the equation by subtracting it from both sides.
2x−x2−1=0
Reorder the polynomial.
−x2+2x−1=0
Answer and Step-by-step explanation:
Standard form of an equation is as follows:
Ax + By = C
We have 2x, -[tex]x^{2}[/tex], and a 1.
Subtract 1 from both sides.
[tex]-x^{2} + 2x - 1[/tex] = 0 is the equation in standard form.

Answer:
A = 53°
AB = 23.3
BC = 18.6
Step-by-step explanation:
2. Given,
C = 90°
B = 37°
AC = 14
Required:
A, AB, and BC
Solution:
✔️A = 180 - (90 + 37) (sum of triangle)
A = 53°
✔️Find AB and BC using trigonometric function:
Reference angle = 37°
Opp = 14
Hyp = AB
Adj = BC
To find AB, apply SOH:
Sin 37 = Opp/Hyp
Sin 37 = 14/AB
AB = 14/Sin 37
AB = 23.262962 ≈ 23.3 (nearest tenth)
To find BC, apply TOA:
Tan 37 = Opp/Adj
Tan 37 = 14/BC
BC = 14/Tan 37
BC = 18.5786275 ≈ 18.6 (nearest tenth)
Which translation vector moves every point of a pre-image 4 units left and 6 units up?
F. (4, -6)
G. (-4, 6)
H. (-6, 4)
J. (6, -4)
Answers
Answer:
G(-4,6)
Step-by-step explanation:
Here, we want to write a translation
moving left means we are to subtract the number of units from the original
So we have this as -4
Moving up means we are to add the number of units to the original
So we have this as +6 = + 6 units
So the answer here will be;
(-4,6)
G. (-4, 6).
Given translation is 4 units left and 6 units up.
For left we use negative sign. And for up was use plus sign.
So the translation vector is (-4, 6).

Step-by-step explanation:
Supplementary angles are angles whose measures sum to 180°.
equation for supplementary angle~ a+b=180
Example:
2x+(2x–2)=180
4x–2=180
4x=182
x=45.5
Answer:
x = 100.5
Step-by-step explanation:
Supplementary angles are two angles that have a sum of 180°. THIS MEANS WE'RE ADDING.
We can use distributive property to solve this equation.
x + (x-21) = 180°.
x + x - 21 = 180°.
Now, we can combine like terms.
2x - 21 = 180.
Since there is a subtraction sign in front of the number 21, we do the opposite operation (addition).
Next, we add 21 to 180.
180 + 21 = 201.
2x = 201
Lastly, we divide 201 by 2.
The quotient is 100.5.
100.5 is the final answer.
Therefore, 100.5 is the value of x.
We can check our answer to make sure.
(100.5 - 21) + 100.5 =
79.5 + 100.5 = 180°.

Which statement is true about the diameter of a circle?
The diameter has 3 endpoints.
The diameter is one half the length of a radius.
The diameter must pass through the center of the circle.
A diameter is not a chord.
A diameter is a type of radius.
Answers
Answer:
The diameter must pass through the center of the circle.
Step-by-step explanation:
TRUE STATEMENT :
The diameter must pass through the center of the circle.
Answer:
A. Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
Step-by-step explanation:
The only way to answer this question is to check the definitions of chord and diameter.
A chord is a segment with endpoints on the circle. In the attached figure the segments CD and GH are chords.
Now, notice that according to the given definition the segment EF is also a chord, but with the special characteristic that the center of the circle, denoted by A, it is on the segment. This ‘‘special’’ chords that contains the center of the circle are called diameter.
Sometimes the diameters are also called the larger of the chords.

Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?
Answers
Answer:
3.00 years
Step-by-step explanation:
Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?
Your answer
Given data
Principal= $85
Rate= 4.5%
Intterest= $11.48
The simple interest formula is
SI= PRT/100
11.48= 85*4.5*T/100
cross multiply
11.48*100= 85*4.5*T
1148=382.5T
divide both sides by 382.5
T= 1148/382.5
T= 3.00 years
Hence the time is 3 years
En una escuela hay 12 paquetes,cada uno con 2 resma de papel de 500 hojas.Van a repartir las hojas en partes iguales entre los 10 grados dela escuela.¿cuantas hojas le darán a cada grado?
Answers
Answer:
A cada grado podrían darle, o 600 hojas en un caso.
O bien, 1200 hojas.
Step-by-step explanation:
Total de paquetes: 12
Cada paquete tiene, 2 resmas con 500 hojas lo cual se entendería que en cada resma hay 250 hojas
(Como son 2 resmas el total es de 500 hojas)
Si cada paquete tiene 500 hojas y hay 12 paquetes
500 hojas/paquete . 12 paquetes = 6000 hojas
6000 hojas / 10 grados = 600 hojas para cada grado.
Si pensamos que en 2 resmas de papel hay 500 hojas cada paquete tendría un total de 1000 hojas ya que:
2 resmas . 500 hojas/resma = 1000 hojas.
Si son 12 paquetes, 1000 hojas/paquete . 12 paquetes = 12000 hojas.
12000 hojas repartidas en 10 grados, son (12000 /10) = 1200 hojas.

QUESTION 2. Trapezoid QRST has two right angles. A 5in altitude can be drawn dividing QRST into a rectangle and an isosceles right triangle. The longer side of the rectangle measures 9in. What is the area of the trapezoid ?
Answers
Answer:
The area of the trapezoid is 57.5 in.²
Step-by-step explanation:
The given information of the trapezoid are;
The vertices of the trapezoid = QRST
The altitude of the trapezoid = 5 in.
The shape the altitude divides the trapezoid into = A square and an isosceles right triangle
The long side of the rectangle = 9 in.
Therefore, we have;
The legs of an isosceles right triangle are equal
Given that one of the legs of the isosceles right triangle = The altitude of the triangle = 5 in.
Therefore, for the isosceles triangle, the length of the other leg = 5 in.
Therefore;
The area of the right triangle = 1/2 × Base × Height (altitude)
The area of the right triangle = 1/2 × Leg × leg = 1/2 × (Leg)²
∴ The area of the right triangle = 1/2 × 5 in. × 5 in. = 12.5 in.²
The length of the rectangle is given as l = 9 in.
The height of the rectangle, h = The altitude of the rectangle = 5 in.
The area of the rectangle, A = l × h
∴ The area of the rectangle, A = 9 in. × 5 in. = 45 in.²
The area of the trapezoid = The area of the right triangle + The area of the rectangle
The area of the trapezoid = 12.5 in.² + 45 in.² = 57.5 in.²
