Answer 1

Answer:

lines a and b are parallel because their corresponding angles are congruent.

Step-by-step explanation:

Since there are two angles equal to 110 in the same position, lines a and b are parallel because their corresponding angles are congruent.

Given the diagram below find the value of x

Answers

Answer:

x = 15

Step-by-step explanation:

a straight line has the angle of 180 degrees

so when added together both angles should equal 180

4x - 17 + 137 = 180

then combine like terms

4x + 120 = 180

and then subtract

4x = 60

and then divide

x = 15

and that is your answer

True of False? The blue radius is perpendicular to the green chord

Answers

Answer:

Step-by-step explanation:

true i think

The statement that the blue radius is perpendicular to the green cord is false.

What are radius and chords?

The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle.

From the complete question,

The blue radius does not bisect the green chord

This means that the blue radius and the green chord do not meet at 90 degrees

Since both lines do not meet at 90 degrees, then they are not perpendicular

Hence, the statement that the blue radius is perpendicular to the green cord is false

What are the coordinates of the vertex for f(x) = 3x^2 + 6x + 3? (1 point)

Group of answer choices

(−1, 0)

(3, 6)

(0, −1)

(6, 3)

Answers

Answer:

vertex = (- 1, 0 )

Step-by-step explanation:

Given a parabola in standard form

f(x) = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

f(x) = 3x² + 6x + 3 ← is in standard form

with a = 3, b = 6 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{6}{6}[/tex] = - 1

Substitute x = - 1 into f(x) for corresponding y- coordinate of vertex

f(- 1) = 3(- 1)² + 6(- 1) + 3 = 3(1) - 6 + 3 = 3 - 6 + 3 = 0

vertex = (- 1, 0 )

find surface area!!

Answers

Step-by-step explanation:

The figure consists of 6 rectangle and 2 triangle faces.

Surface area (excluding bottom side) is:

S = 2(2.4*1.6 + 1.3*1.6 + 1.5*1.6 + (1/2)*2.4*0.9) = 18.8 yd²

Total surface area (including bottom side):

A = 18.8 + 2.4*1.3 = 21.92 yd²

Liam invests $3,670 in a savings account at his local bank which gives 1.9% simple annual interest. He also invests $2,040 in an online savings account which gives 5.5% simple annual interest. After five years, which one will have earned more interest, and how much more interest will it have earned, to the nearest dollar?

Answers

Step-by-step explanation:

Given:

Investment P₁ = $3670Investment P₂ = $2040Rate of interest r₁ = 1.9% SIRate of interest r₂ = 5.5% SITime t = 5 years

Find amount of interest in both investments:

I₁ = P₁r₁t = $3670*(1.9/100)*5 = $348.65I₂ = P₂r₂t = $2040*(5.5/100)*5 = $561.00

As we see the online savings account earns more interest and the difference is:

$561.00 - $348.65 = $212.35 ≈ $212

(4,-2)?
A. 3x + 10 = y
B. 3x – 14 = y
C. -*-=y
D. --*x+10=y

Answers

Hello! (:

3x+4=y

We want to convert it into slope-intercept form:

y=mx+b

Our equation looks like this:

y=3x+4

Now, parallel lines have the same slope. So if one line has a slope of 3, the line parallel to it has a slope of 3 as well.

Now, we have the slope and a point, so we write the equation in point-slope form:

y-y1=m(x-x1)

y-(-2)=3(x-4)

y+2=3x-12

y=3x-12-2

y=3x-14

Hence, that is the required equation, Hope it helps you!

Find the equation of the line, whose slope is 5 and x- intercept is 2

Answers

Answer:

Step-by-step explanation:

when x intercept is points given, then y = 0

So far, you have y = 5x + b where b = the yintercept

x = 2

y = 0

0 = 5x + b

0 =5 * 2 + b

0 = 10 + b Subtract 10 from both sides.

-10 = b

Equation: y = 5x - 10

Answer:

x=m: x-5=m which means m-5=m which means 5=0 which means No Solutions

x=5: x-5=m which means 5-5=m which means m=0

x=m+5: m+5-5 which means m-0=m which means No solutions

What is the length of the missing side, to the nearest tenth of a centimeter?

Answers

Answer:

18.4 cm

Step-by-step explanation:

For this problem, you would use Pythagorean Theorem or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. Picture the 90 degree angle as an arrow pointing to the hypotenuse. In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug!

3) 12 +(-3) = 9

4) x + (-7) = 5

x - 7 = 5

x = 5 + 7

x = 12

We need to add 12 to (-7) to get 5

5) 7 - x = -5

7 = -5 +x

7 + 5 = x

12 = x

We need to take away 12 to 7 to get (-5)
