Step-by-step explanation:
Find the solutions to the equation below.
Check all that apply.
x^2 - 25 = 0
A. x = 1
B. x = 5
C. x = -1
D. x = -5
E. x = 3
F. x = -3
Answer:
B and D
Step-by-step explanation:
x² - 25 = 0
Add 25 to both sides:
⇒ x² -25 + 25 = 0 + 25
⇒ x² = 25
Square root both sides:
⇒ √x² = √25
⇒ x = ±5
Therefore:
x = 5, x = -5
So B and D are the solutions
The value of a graphed function doubles for each increase of 1 in the value of x. Which of the following could be the parent function of the graphed function? y = 2 Superscript x y = x squared y = StartAbsoluteValue x EndAbsoluteValue y = StartRoot x EndRoot
The parent function of the graph is an exponential function
The equation of the parent function could be y = 2^x
How to determine the possible parent function?From the question, we understand that:
y doubles, as x increases by 1
The above means that the parent function is an exponential function that has a rate of 2
So, we have:
y = 2^x
Hence, the equation of the parent function could be y = 2^x

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4
Answer:
[tex]\sf y=-\dfrac12x+2[/tex]
Step-by-step explanation:
y-intercept is when x = 0, so (0, 2)
x-intercept is when y = 0, so (4, 0)
[tex]\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12[/tex]
Slope-intercept form of linear equation: [tex]\sf y=mx+b[/tex]
(where m is the slope and b is the y-intercept)
Given:
[tex]\sf m=-\dfrac12[/tex]b = 2[tex]\sf \implies y=-\dfrac12x+2[/tex]

Geometry is so confusing to me, i don’t get how to figure out angles and measurements. I have read my instructors over and over again and I still don’t understand
Answer:
reference attached
Step-by-step explanation:
hope it helps you <3Answer:
It's ok. Math can be really difficult, but don't give up and you'll understand.
To begin, this is a transversal. A transversal is a set of parallel lines that have a third line intersecting them.
In the photo below, you can see the original angle given and it is 35°. On the same line directly across from it is an angle that is also 35°. This follows the rule of vertical angles, which are angles produced by the same two lines. It also states that they are congruent.
You'll also see that the angle next to the original angle is 145°. This follows the rule of supplementary angles, which states that two angles that are on the same straight line will equal 180° when added together.
The angle opposite to that is 145°, which can be proven by vertical angles.
Through a method called corresponding angles, we can see that the original angle is corresponding with the angle below it.
Then you would repeat the process for the top.
Hope this helps!
surface area.... again
Answer:
1848 square inches
Step-by-step explanation:
surface area is the combined area of all the outside surfaces.
area of triangle is base x height / 2
There are two, so no need to divide
18 x 12 = 216
Area of rectangle is base x height
15 x 34 + 15 x 34 + 18 x 34 = 1632
Then add
216 + 1632 = 1848

Answer:
13) 80 in sq
14) You can find the area of the bigger rectangle, then subtract it from the area of the unfilled white rectangle.
15) The smallest possible area is 38 inches by contiguously placing the cards, or placing the on the adjacent side of 4 inches.
Step-by-step explanation:
Answer:
13) easy but long way, count all the blue squares
harder way but fast way, multiply length and width of blue box and subtract length*width of white box inside of blue box the answer would be 80
14) basically the harder way but fast way mentioned above
15) the smallest possible perimeter is achieved when you calculate less of the longer side and more of the short side. therefore, lining the pictures with the 4inch side as the length and 5 inch side as the width in a line, it would give you a perimeter of 5+5+4+4+4+4+4+4=34
Step-by-step explanation:
13: remember, these are coordinates and not the actual number.
these are the measurements of the blue box
length, 16-2 = 14
width, 14-4=10
these are the measurements of the white box inside the blue box
length, 14-4 =10
width, 12-6=6
find area of both which comes to 140 and 60. subtract 60 from 140 to get 80

In ΔGHI, the measure of ∠I=90°, IH = 11, HG = 61, and GI = 60. What is the value of the sine of ∠G to the nearest hundredth?
Answer: 0.18
Step-by-step explanation:
Using the sin rule:
11/sin(∠G) = 61/90
sin(∠G) = 11/61
sin(∠G) = 0.18°
Therefore, the value of angle G is 0.18 degrees

What is the period and frequency of the function graphed and how would the equation be written??
Answer:
Period: 6, Frequency: 1/6, Equation: -4cos([tex]\frac{\pi }{3}x[/tex])-2
Step-by-step explanation:
Because the graph starts at x = 0 at a minimum/maximum, it's easiest to use cosine, so we don't have to shift the graph horizontally. cos(x)
If you take the max/min points and average them, you can use the distance between the average value and the max/min to get the total amplitude, A, which is 4.
Because this function starts at a minimum, but cosine starts at a maximum, we will flip it vertically by adding a negative coefficient to whatever the amplitude is.
We see that the same part of the graph recurres every 6 x-units, so the period is 6. The frequency of this is 1/(period), 1/6.
The coefficient of x in a sin/cos function is [tex]2\pi /Period[/tex], = [tex]\pi[/tex]/3.
The vertical shift (how much the average value of the function moved from 0 to its current position) is -2.
Put all that together, you get y = -4cos([tex]\frac{\pi }{3}x[/tex])-2
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
let's solve ~
Period :
Difference between two successive crest or trough is known as period, so here :
period = 9 - 3 = 6
Frequency
Now, we know that frequency = 1/period
So, frequency for given function is 1/6 hertz , or approximately 0.167 hertz
Amplitude (A) = 4 (flipped)b = 2π ÷ Period = 2π /6 = π/3 k = -2The required equation is ~
[tex]\qquad \sf \dashrightarrow \:y = a \cos(bx) + k[/tex]
[tex]\qquad \sf \dashrightarrow \:y = - 4 \cos( \frac{ \pi}{3} x) - 2[/tex]
