Usually, when reading the recipe for making cupcakes or any food that requires flour, the unit used would most likely be "cups"

suppose a band at another school sells eraser for $2 per package. the band sells 220 package in all and earns a total of $695. w

mr_godi [17]

X= # of eraser packages = 135
y= # of pencil packages = 85

cost = 2x + 5y = 695
# of items = x+y= 220
   2x+5y=695
-2x -2y=-440
3y   255
----- = ------- y=85 x+(85) / 220
3 3 ----- -----
-85 -85

x=135
2(135) + 5 (85) ?695
270+425?695
695+695

The scale of a map is 1 cm : 76 km. What is the actual distance between two towns that are 5 cm apart on the map?

rodikova [14]

The towns would be 380 km apart. You find this by multiplying the scale accordingly (in this case 5*76)

Cosine is the square root of 3 over 2. How do I find the secant expression without a square root in the denominator by rationali

konstantin123 [22]

Hello,

$cos(x)= \dfrac{ \sqrt{3} }{2} \\
sec(x)= \dfrac{1}{cos(x)} = \dfrac{1}{\dfrac{ \sqrt{3} }{2}} =\dfrac{ 2*\sqrt{3} }{\sqrt{3}*\sqrt{3}}=\dfrac{2*\sqrt{3}}{3}$

Generate six Pythagorean triples using any method discussed during class. Explain each method you use.

Yuri [45]

Answer:

1) (3,4,5)

2) (6,8,10)

3) (8,15,17)

4) (10,24,26)

5) (5,12,13)

6) (33,56,65)

Step-by-step explanation:

There are many ways of generating Pythagorean triples (a,b,c), one of the easiest ones is to take two natural numbers n and m, and we will have:

a = n² - m²,

b = 2nm,

c = n² + m²

Then (a, b, c) is a Pythagorean triple.

So, we're going to generate 6 Pythagorean triples using this method.

1. m= 1 and n = 2

⇒a = 2² - 1² = 3

b =2(1)(2) = 4

c= 1² + 2² = 5

and the triple is (3,4,5)

2. Now for m = 1 and n = 3

⇒a = 3²-1² = 8

b= 2(3)(1) =6

c = 1²+3² = 10

and the triple is (6,8,10)

3. Now for m = 1 and n = 4

⇒a = 4²-1²=15

b=2(1)(4)=8

c= 4²+1²=17

And the triple is (8,15,17)

4. Now for m = 1 and n =5

⇒a = 5²-1²=24

b=2(1)(5)=10

c= 5²+1²=26

and the triple is (10,24,26)

5. m = 2 n = 3

⇒a = 3²-2²= 5

b= 2(2)(3)=12

c= 3²+2²= 13

And the triple is (5,12,13)

6. m= 4 n = 7

⇒a= 7²-4²=33

b=2(7)(4)=56

c= 4²+7²= 65

And the triple is (33,56,65)

Find the vertex, focus, directrix, and focal width of the parabola. negative 1 divided by 12 times x squared = y

notka56 [123]

negative 1 divided by 12 times x squared = y

$\frac{-1}{12} x^2=y$

To find vertex we use formula x= -b/2a

From the given equation a= -1/12 and b =0

Plug in the values in the formula

$x= \frac{0}{\frac{-1}{12}} =0$

Now plug in x=0 in the given equation and find out y

$\frac{-1}{12}(0)^2=y$

So y=0

Hence vertex is (0,0), h=0 and k =0

Focus is (h, k+p)

We need to find out p

We know a= -1/12

p = 1/4a

$p = \frac{1}{4\frac{-1}{12}} = -3$

So focus is (0,0-3) that is (0, -3)

Directrix is y = k - p

We know p = -3 and k=0

y = 0 -(-3) = 3. so directrix is y = 3

Focal width = |4p|

We know p = -3

so it becomes |4(-3)| = 12

Focal width = 12
