If the discriminant of an equation is positive, which of the following is true of the equation
A it has one complex solution
B it has one real solution
C it had two real solutions
D it has two complex solutions

Answers

Answer 1

Answer:

C it has two real solutions

Step-by-step explanation:

If the discriminant of a quadratic equation is positive, it means that the graph intersects the x-axis, and hence produces two real solutions.

If the discriminant is zero, then the graph is tangential to the x-axis, and there will be two real coincident solutions.

If the discriminant is negative, then there are two complex solutions.

if each box represents 1 miles, what is the shortest distance from the school to the skate park.

Answers

The shortest distance between two points is a straight line.

Use the distance formula for points.

In the diagram, we are given two points:

(4,2) and (-3,0).

Let d = distance between the two points.

d = sqrt{(-3 -4)^2 + (0-2)^2}

d = sqrt{(-7)^2 + (-2)^2}

d = sqrt{49 + 4}

d = sqrt{53}

d = 2.2360679775

d = 2.2 miles

Answers

Question:

Plot two points that are 8 units from Point B and also share the same x-coordinate as Point B

See attachment for grid

Answer:

See attachment for plot

Step-by-step explanation:

See comment for complete question

From the attached image, we have:

[tex]B = (-6,0)[/tex]

Required

2 points that are 8 units away and on the same x coordinate

Let the two points be [tex]C\ and\ D[/tex]

The first condition is that; C and D must be on the same x coordinate as B.

So, we have:

C = (-6,_)

D = (-6,_)

8 units from B implies that we add or subtract 8 from the y coordinate of B.

So, we have:

[tex]C = (-6,0+8)[/tex]

[tex]D = (-6,0-8)[/tex]

[tex]C= (-6,8)[/tex]

[tex]D= (-6,-8)[/tex]

Answer: [tex]7,5.66,39^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]IJ=9\\\angle I=51^{\circ}[/tex]

from figure, we can write

[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]

[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]

In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]

[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]

Answers

Answer:

The least common multiple of 50, 18 and 32 is 7200.

Step-by-step explanation:

mark brainleist plz

Answer:

LCM = 7200

Step-by-step explanation:

LCM(18, 32, 50) =

LCM(LCM(18, 32), 50)

Working from the innermost parentheses outward:

LCM(18,32) = (18 × 32) / GCF(18,32)

= (18 × 32) / 2

= 576 / 2

= 288

LCM(288,50) = (288 × 50) / GCF(288,50)

= (288 × 50) / 2

= 14400 / 2

= 7200

Therefore,

LCM(18, 32, 50) = 7200

m∠BFE = 171º

BE = 219º

Step-by-step explanation:

∠BFE is supplementary to ∠EFC

m∠BFE = 180 - 9

m∠BFE = 171º

--------------------------

The angle between two chords is equal to half the sum of the intercepted arcs:

∠BFE = (DC + BE)2

171 = (123 + BE)/2

342 = 123 + BE

219º = BE

Maria is making a fruit punch. There are 15.75 ounces of orange juice in a container. Maria pours 2.25 ounces of cranberry juice into the container each second. How many ounces of fruit punch are in the container after 9 seconds?

Answers

Answer:

20.25 ounces

Step-by-step explanation:

We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;

[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]

Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex] then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)

[tex]1\cdot \:x=2.25\cdot \:9[/tex]

Simplify

Multiply by 1

[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]

Multiply the numbers

[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]

Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.

In addition to the brutality Hussein inflicted on his people, including the use of chemical weapons, the Bush Administration believed Hussein was in possession of weapons of mass destruction. Colin Powell appeared before the United Nations to show aerial photographs that were interpreted as proof that Iraq was pursuing a nuclear weapon. Husseins refusal to cooperate with international inspectors lent credence to this belief. Further, the President accused Hussein of cooperating with al-Qaeda. Prior to beginning the invasion, the Bush Administration presented justification to the United Nations, and also attempted to resolve the nuclear weapon issue by working with the International Atomic Energy Agency.
