Identify the angles of rotational symmetry for the figure.

miss Akunina [59]

I saw 180, 90, 45. That’s only because 360/8=45 so it’s symmetrical when rotated by a multiple of 45. Hope that helps

What is the equation of the line through (5,1) with a slope of -3?

PilotLPTM [1.2K]

Answer:

C

Step-by-step explanation:

The equation of a line is given by the formula $y-y_1=m(x-x_1)$

Where $x_1$ is the x-coordinate (it is given as 5)

$y_1$ is the y-coordinate (it is given as 1), and

m is the slope (it is given as -3)

Plugging in all the info into the formula we have:

$y-y_1=m(x-x_1)\\y-1=-3(x-5)$

From the answer choices, we see that C is the correct answer.

Andrea conducts a science experiment and observes that the height of a plant depends on the amount of sunlight it receives. The

valentina_108 [34]

Answer:

f(h) = 0.004s + 37

Step-by-step explanation:

The correct representation of the height of the plant is;

f(h) = 0.004s + 37

Given parameters;

Height of plant = 37cm

Rate of growth = 0.004cm/hr

Number of hours of sunlight = s

To solve this problem, the height of the plant is directly dependent on the amount of sunlight;

f(h) signifies that height is a function

The height of the plant is 37cm;

f(h) = 37

The plant grows at a rate of 0.004cm/hr; number of hours of sunlight is s;

0.004s

Therefore;

f(h) = 37 + 0.004s

Find the value of c that makes the expression a perfect square trinomial.<br><br> x2 + 4x + c

masha68 [24]

the value of c that makes the expression a perfect square binomial is c=4 .

<u>Step-by-step explanation:</u>

Here we have , an expression x2 + 4x + c or , $x^2 + 4x + c$ . We need to find the value of c that makes the expression a perfect square binomial. Let's find out:

We have , $x^2 + 4x + c$

⇒ $x^2+4x+c$

⇒ $x^2+2(2)x+c$

Now , we know that $(a+b)^2=a^2+2(a)(b)+b^2$

Comparing above equation , to $x^2+2(2)x+c$ we get ;

⇒ $x^2+2(2)x+c$ { $c=2^2$ }

⇒ $x^2+2(2)x+2^2$

⇒ $(x+2)^2$

Therefore , the value of c that makes the expression a perfect square binomial is c=4 .
