Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.

It is A because it is only $40.000 so therefore it is A.

Answer:

for question 3 - b

for question 4- b

Step-by-step explanation:

Answer:

y = 312x + 2

Step-by-step explanation:

According to y = mx + b, m stands for slope and b stands for y-intercept. Let us find the y-intercept. To find the y-intercept, the x should be zero in (x, y).

(x, y)

(0, 2) ---> y-intercept (b)

Now that we have found the y-intercept, we will now find the slope by using its formula.

Slope formula:-

m = y2 - y1 / x2 - x1

Pick two random (x, y). I will pick the first and last pairs.

(0, 2) and (4, 1250)

Now plug these two pairs in the formula.

m = y2 - y1 / x2 - x1

m = 1250 - 2 / 4 - 0

m = 1248 / 4

m = 312

This means that the slope (m) is 312. Now put that in y = mx + b form.

y = mx + b

y = 312x + 2

Both of the forms are the same. Hope this helps, thank you :) !!

Answer:

x = 7, x = 5

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord.

(1)

27x = 9 × 21 = 189 ( divide both sides by 27 )

x = 7

(2)

12(3x - 5) = 120 ( divide both sides by 12 )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Answer: 78°

Similar triangles are different from congruent triangles. Congruent triangles have equal angles and sides, while similar triangles have equal angles and proportional side lengths. In this case, because the triangles are similar, the angles should be equal. The sum of the angles of triangles are always 180°. Because triangle ABC has angle measures of 28° and 74°, the equation should appear as 28+74+x=180. Add the like terms to get 102. Subtract 102 on both sides to get x=78. Although we only solved for Triangle ABC, again, similar triangles have the same corresponding angle measures, so it applies to Triangle DEF, as well.

Answer: Option B

Step-by-step explanation:

Answer:

y = -3x - 3

Step-by-step explanation:

y = -3x + b

0 = -3(-1) + b

0 = 3 + b

-3 = b

y = -3x - 3

Answer:

Cost of cell phone in U.S. dollar = 100 U.S. dollar

Step-by-step explanation:

Given:

Cost of cell phone in yen = 8,835.3 yen

1 U.S. dollar = 88.353 yen

Find:

Cost of cell phone in U.S. dollar

Computation:

Cost of cell phone in U.S. dollar = Cost of cell phone in yen[1 /  88.353]

Cost of cell phone in U.S. dollar = 8,835.3[1 /  88.353]

Cost of cell phone in U.S. dollar = 8,835.3 /  88.353

Cost of cell phone in U.S. dollar = 100 U.S. dollar

Answer:

A.

[tex] SA= \frac{2}{3} \pi rl+16 \pi r^2[/tex]

Step-by-step explanation:

Surface area of the original cone

[tex] SA= \pi r l + \pi r^2... (1)[/tex]

When, radius is quadrupled and slant height is reduced to one sixth

[tex] i. e. \: \:r = 4r\: \: \&\:\: l= \frac{1}{6}l[/tex]

Plug the above values of r and [tex] l[/tex] in equation (1), new surface area becomes:

[tex] SA= \pi (4r)\times \frac{1}{6} l+ \pi (4r)^2[/tex]

[tex] SA= \frac{4}{6} \pi rl+16 \pi r^2[/tex]

[tex]\huge \purple {\boxed {SA= \frac{2}{3} \pi rl+16 \pi r^2}} [/tex]

Answer:

Step-by-step explanation:

 h

------ - 1 = -3

  6

To solve for h, first add 1 to both sides to isolate h/6:

h

---- = -2

 6

Now isolate h by multiplying both sides by 6:

h = -12

Answer:

h is -12

Step-by-step explanation:

Answer:

down there with the work :)

Step-by-step explanation:

formula: a^2+b^2=c^2

Page 1:

1)

6^2+8^2=c^2

36+64=c^2

100=c^2

take the square root of both sides

c=10

2)

8^2+b^2=12^2

64+b^2=144

80=b^2

b=[tex]4\sqrt{5}[/tex]

3)

14^2+b^2=48^2

196+b^2=2304

b^2=2108

b=[tex]2\sqrt{527}[/tex]

Page 2:

1)

5^2+11^2=13^2

25+121=169

no this is not true so this is not a right triangle

2)

10^2+24^2=26^2

100+576=676

this is true so this IS a right triangle

hope this helps!

Answer:

10

Step-by-step explanation:

distance formula = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

(x_1, y_1) = (5, 1)

(x_2, y_2) = (-3, -5)

\sqrt{ [(-3) - (5)]^2 + [(-5) - (1)]^2 }

\sqrt{ [-8]^2 + [-6]^2 }

\sqrt{ 64 + 36 }

\sqrt{ 100 }

= 10

Answer:

[tex] Distance = 10 \ u [/tex]

Step-by-step explanation:

Given :-

And we need to find the distance between the two points . We can use distance formula here to find the distance between the two points . The distance formula for two points ,

Distance Formula :-

[tex]\implies Distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\implies Distance =\sqrt{\{5-(-3)\}^2+\{1-(-5)\}^2 } \\\\\implies Distance =\sqrt{ (5+3)^2+(1+5)^2}\\\\\implies Distance =\sqrt{ 8^2+6^2}\\\\\implies Distance =\sqrt{64+36}\\\\\implies Distance =\sqrt{100}\\\\\implies Distance = 10\ units [/tex]

Hence the distance between the two points is 10 units .

Answer:

B) The value of r would not change

Step-by-step explanation:

If there's a positive association between sodium and calories, that's like saying there's a positive association between calories and sodium. Therefore, the value of r would not change because both variables are still increasing with each other.
