does anyone know this? slope: 1/4 y-intercept:3
Answer:
are you looking for the equation? y = 1/4x + 3
Step-by-step explanation:
Answer: Yes. So you need to plot this on a graph? I know how to plot it. So since the y-intercept is 3 you would put a point on 3 and then from there go up one and over 4 since we use the rise/run method. does this make sense?

n
, the n^{\text{th}}n
th
term of the sequence 25, 32, 39, ...25,32,39,....
Answer:
7n + 18
Step-by-step explanation:
it goes up in 7 so 7n and 25-7 =18
The Explicit formula for nth term is 18 + 7n.
What is Explicit Formula?It is simple to calculate the explicit formula for the arithmetic sequence from the term of the sequence.
The explicit formula for the arithmetic sequence a, a + d, a + 2d, a + 3d,........a + (n - 1)d, and the nth term of the sequence.
We have the sequence 25, 32, 39, ....
This is an arithmetic sequence.
First term = 25
and, Common difference(d) = second term - first term = 32-25 = 7
Now, the nth term of sequence
= a + (n- 1)d
= 25 + (n-1)7
= 25 + 7n - 7
= 18 + 7n

hcm
What is the value of h?
Give your answer correct to 1 decimal place.
Answer:
h = 9.87 cm
Step-by-step explanation:
Given that,
Base, b = 8 cm
Height = h
Angle, [tex]\theta=51^{\circ}[/tex]
We need to find the value of h. We can use trigonometry to find h.
[tex]\tan\theta=\dfrac{\text{Perpendicular}}{\text{Base}}\\\\\tan(51)=\dfrac{h}{8}\\\\h=\tan(51)\times 8\\\\h=9.87\ cm[/tex]
So, the height of the triangle is 9.87 cm.

Answer:
10.8 m²
Step-by-step explanation:
To find area, we do 3.14*r^2
since diameter = 2 radius divide each by 2
2 and 0.75
A outer= 3.14*2^2
3.14*4
12.56 m²
A inner = 3.14*0.75^2
≈1.8 m²
to find the shaded area subtract the outer from the inner
12.56-1.8=10.76
which rounds up to
10.8 m²
If we use π then we get
about
12.57
and
1.77
subtract to get
10.8 m²
