Answer:
y = 4slope: 0slope of perpendicular: undefinedStep-by-step explanation:
The x-axis is a horizontal line. As such, it has a slope of zero. The equation of a horizontal line is ...
y = constant
__
For the line through (-5, 4), the constant must match the y-coordinate: 4. The equation is ...
y = 4
As we said above, the slope of that horizontal line is zero.
The perpendicular line will be a vertical line of the form x=constant. The slope of a vertical line is undefined.
How high up on a wall will a 20-foot ladder touch if the foot of the ladder is placed
4 feet from the base of the wall?
Step-by-step explanation:
by using the pythagoras theorem,
the height of the ladder touching the wall =
√(20²- 4²)
=√ (400-16)
=√384
= 8√6 feet
or 19.6 feet
Using Pythagorean theorem
[tex]\\ \rm\longmapsto P^2=H^2-B^2[/tex]
[tex]\\ \rm\longmapsto P^2=20^2-4^2[/tex]
[tex]\\ \rm\longmapsto P^2=400-16[/tex]
[tex]\\ \rm\longmapsto P^2=384[/tex]
[tex]\\ \rm\longmapsto P=\sqrt{84}[/tex]
[tex]\\ \rm\longmapsto P=19.6ft[/tex]

How to find the standard form of polynomial?A polynomial can have constants, variables and exponents, but never division by a variable. example of a polynomial is as follows:
4xy² + 2y + 5
Polynomial can be named base on the number of terms. For example monomial, binomial and trinomial.
The standard form of a polynomial is expressed by writing the highest degree of terms first then the next degree and so on.
Therefore, the polynomial in standard form is as follows;
8x⁵ - 5y⁴ - 2xy⁵ + x²y

please help!!! i cant figure it out
Step-by-step explanation:
Hi there!
Given;
f(x) = 17x + 9
h(x) = 4x
To find: f(x)-h(x)
f(x)-h(x)= 17x + 9 - 4x
= 13x + 9
Therefore, f(x)-h(x) = 13x + 9.
Hope it helps!

Which fraction is greater,2/3 or 25/15?
Answer:
[tex]\frac{25}{15}[/tex] is greater.
Step-by-step explanation:
25÷15=1.67
2÷3=0.67
1.67 is greater than 0.67, so [tex]\frac{25}{15}[/tex] is greater.
Also, [tex]\frac{25}{15}[/tex] is an improper fraction, and [tex]\frac{2}{3}[/tex] is a proper fraction. Improper fraction mast be greater than a proper fraction.

you invested 5000 between two accounts paying 3% and 7% annual intrest. If the total intrst earned for the year was $310, how much was invested at each rate?
Answer:
The total interest of $320 will be the sum of the amount earned in each account.
Step-by-step explanation:
320 = x(0.04)(1) + (5000-x)(0.08)(1)
320 = 0.04x + 400 - 0.08x
-80 = -0.04x
2000 = x
5000 - x = 3000
$2,000 was invested at 4%
$3,000 was invested at 8%

what is the answer for 23/4 + -23/4 - -15/4 + 9/4
Answer:
[tex]-\frac{6}{4}[/tex]
Step-by-step explanation:
The first 2 numbers cancel, and -15/4+9/4 is the same as 9/4 - 15/4
Please mark me as brainliest if I am correct
Answer:
6
Step-by-step explanation:
In the equation, [tex]\frac{23}{4} + -\frac{23}{4} --\frac{15}{4} + \frac{9}{4}[/tex], we can see that [tex]\frac{23}{4} + -\frac{23}{4}[/tex] cancel each other out
This leaves us with [tex]--\frac{15}{4} + \frac{9}{4}[/tex]. The negatives "negate" themselves giving us [tex]\frac{15}{4} + \frac{9}{4} = \frac{24}{4}[/tex] or [tex]6[/tex]
Hopefully (some part of) this explanation makes sense (or at least somewhat). If this doesn't make sense, please tell me and I will try to make it more understandable as soon as possible.
It would help if you marked my answer as Brainliest, if I'm correct, so I can help even more people! (I would really appreciate it!)

Answer:
the point is (1.73, 3)
Step-by-step explanation:
Given a vector on an xy plot, the magnitude is the hypotinuse of the triangle formed, and the direction is the angle with x axis. So we have a right angle triangle that must be a 30-60-90 (sum = 180).
Then from the lower angle
sin(60) = opposite/hypotinuse = y/(2*3**(1/2))
0.866 = y/(2*1.732)
0.866 = y/3.464
0.866 * 3.464 = y
3 = y
Then from the top angle
sin(30) = opposite/hypotinuse = x/(2*3**(1/2))
sin(30) = x/(2*3**(1/2))
0.5 = x/(2*3**(1/2))
0.5 = x/3.464
0.5 * 3.464 = x
1.73 = x

Part A: If (2^6)^x = 1, what is the value of x? Explain your answer.
Part B: If (5^0)^x = 1, what are the possible values of x? Explain your answer.
2 points for each answer; 2 points for each explanation.
Answer:
Step-by-step explanation:
2^6 = 64 and the only power of 64 that gives us 1 is 64^0 = 1. S0 x = 1.
Now 5^0 is already 1. Then (5^0)^x =1^x is equal to 1 for any value of x.
