Answer:

x>=1

Step-by-step explanation:

I will give you a simple definition for Closed and Open number lines.

Closed circles in this number line mean INCLUDING 1 and everything greater so X>=1, or row 2 column 1.

HELP ASAP GEOMETRY CIRCLES 10TH GRADE

Aleksandr-060686 [28]

Answer:

a): 68

b): 32

Step-by-step explanation:

In a triangle, there is a total of 180 degrees

We are given 2 out of the 3 angles, 54 and 58 degrees

180-54-58= 68 degrees

In the other angle, both lines form a 90-degree angle

We are given 58 degrees, so the rest must be 32.

Q 1 PLEASE HELP ME FIGURE THIS OUT 2

dimulka [17.4K]

Answer: $\frac{\pi }{3}$

Step-by-step explanation:

cot is $\frac{cos}{sin}$ on the Unit Circle. When is cos = $\frac{1}{2}$ and sin = $\frac{\sqrt{3}} {2}$ ? In other words, where is the coordinate $(\frac{1}{2},\frac{\sqrt{3}} {2})$ on the Unit Circle?

It occurs at 60° = $\frac{\pi }{3}$ radians

Answer: cot θ

Step-by-step explanation:

sec (90 - θ) * cos θ

= $\frac{1}{cos (90 -\theta)}$ * cos θ

= $\frac{cos\theta}{cos(90 - \theta)}$

= $\frac{cos\theta}{cos90*cos\theta+sin90*sin\theta}$

= $\frac{cos\theta}{0*cos\theta+1*sin\theta}$

= $\frac{cos\theta}{sin\theta}$

= cot θ

Answer: BC = √5, AC = 2√5

Step-by-step explanation:

$\frac{\pi} {3}$ = 60°, which means ΔABC is a 30°-60°-90° triangle so we can use the side length formulas: x - x√3 - 2x.

∠C is the 60°. It matches to side AB so: AB = x√3 = √15 ⇒ x = √5

∠A is the 30°. It matches to side BC so: BC = x = √5

∠B is the 90°. It matches to side AC so: AC = 2x = 2(√5) = 2√5

Answer: k = 4, RS = 12, QS = 28

Step-by-step explanation:

$\frac{QR}{MN} = \frac{RS}{NO}= \frac{QS}{MO}$

$\frac{24}{6} = \frac{RS}{3}= \frac{QS}{7}$

proportionality constant k can be found with $\frac{QR}{MN}$ = $\frac{24}{6}$ = 4

$\frac{QR}{MN} = \frac{RS}{NO}$

→ 4 = $\frac{RS}{3}$

→ 4(3) = RS

→ 12 = RS

$\frac{QR}{MN} = \frac{QS}{MO}$

→ 4 = $\frac{QS}{7}$

→ 4(7) = QS

→ 28 = QS

Please help im going to cry

bearhunter [10]

Answer:

Stock A

d(1 +0.05)
1.05d
d +0.05d

Stock B

d -0.05d
d(1 -0.05)
0.95d

Step-by-step explanation:

When we say something is increased (or decreased) by a percentage, we mean that the percentage of the original amount is added to (or subtracted from) the original amount.

Of course, you know that 5% = 5/100 = 0.05, so that an increase of 5% in d would be ...

d + 0.05d . . . . . 5% of the original amount (d), added to d

Factoring out d gives another version of this expression:

d(1 +0.05)

and combining the numbers gives yet another version of the same expression:

1.05d

These are the ways that the increase in Stock A can be expressed:

d +0.05d

d(1 +0.05)

1.05d

Similarly, if the "increase" is negative, as for Stock B, we can use the same sorts of expressions. +0.05 gets replaced by -0.05, but the form of the expression is the same.

d - 0.05d . . . . . the original amount decreased by 5%

d(1 -0.05) . . . . .d factored out

0.95d . . . . . . . . the numerical coefficient simplified
