Answer:
b 18÷3=6
Step-by-step explanation:
The fact family contains 3,6and 18
since 3×6=18,18÷6=3and 6×3=18
∴ you need to look for numbers that contain 3,6and18. when you find the number make sure to check that they are not in the question, if it is not in the question then that is your answer.

Write the equation of the line that passes through the points (7, –4) and (–1, 3), first in point-slope form, and then in slope-intercept for
Answer:
8y + 7x - 17 = 0
Step-by-step explanation:
You'll use;
y2 - y1/ x2- x1 = y - y1/x- x1
Which shows an equation in point-slope form of the line shown?
y−2=34(x+6)
y−4=43(x−2)
y−4=34(x−2)
y+2=43(x+6)
An equation in point-slope form of the line shown is: C. y - 4 = 3/4(x - 2)
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (-2 - 4)/(-6 - 2)
Slope (m) = 6/8
Slope (m) = 3/4
At data point (2, 4) and a slope of 3/4, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 4 = 3/4(x - 2)
y - 4 = 3x/4 - 3/2
y = 3x/4 - 3/2 + 4
y = 3x/4 + 5/2

NO LINKS!! A quarterback tosses a football to a receiver 40 yards downfield. The height of the football, f(x), in feet, can be modeled by f(x)= -0.0.25x+x+6, where x is the ball's horizontal distance, in yards, from the quarterback. What is the ball's maximum height and how far from the quarterback does this occur?
Answer:
Maximum height = 16 yards
This occurs 20 yards from the quarterback.
Step-by-step explanation:
Given function: [tex]f(x)=-0.025x^2+x+6[/tex]
To find the maximum (turning point), differentiate the function:
[tex]f('x)=-0.05x+1[/tex]
Set the derivative to zero and solve for [tex]x[/tex]:
[tex]\implies f'(x)=0[/tex]
[tex]\implies -0.05x+1=0[/tex]
[tex]\implies 0.05x=1[/tex]
[tex]\implies x=20[/tex]
Substitute found value of [tex]x[/tex] into the function to find the maximum height:
[tex]f(20)=-0.025(20)^2+(20)+6=16[/tex]
Therefore, the maximum height is 16 yards.
This occurs 20 yards from the quarterback.
The maximum height of the football can be 16 yards and this occurs 20 yards from the quarterback. The concepts of differentiation are used to solve this problem.
Differentiation is a fundamental mathematical concept that is generally used to obtain the rate of change or slopes of a line.
It is given that the height of the football is modeled as the following function:
f(x) = -0.025x² + x + 6
where x is the ball's horizontal distance (in yards) from the quarterback.
To obtain the maximum height of the ball, the equation is needed to be differentiated and set equal to zero as follows:
[tex]\dfrac{d}{dx}f(x) = 0\\\dfrac{d}{dx}(-0.025x^2+x+6)=0\\-0.025\times2x +1 = 0\\-0.05x+1 = 0\\x = \dfrac{1}{0.05}\\x = 20[/tex]
Substitute this value of x in f(x) to find the maximum height,
f(20) = -0.025(20)² + 20 + 6
f(20) = -0.025 × 400 + 26
f(20) = -10 + 26
f(20) = 16
Therefore, the maximum height is 16 yards and this occurs 20 yards from the quarterback.

I've tried this multiple times and cant seem to get the right answer could someone help solve this?
Answer:
[tex]\dfrac{6\pi -9\sqrt{3} }{16}[/tex]
Step-by-step explanation:
You need to rewrite [tex]\cos^2 \theta[/tex] using cos double angle identity:
[tex]\cos 2\theta= \cos^2\theta-\sin^2\theta[/tex]
[tex]\implies \cos 2\theta= \cos^2\theta-(1-\cos^2\theta)[/tex]
[tex]\implies \cos 2\theta=2 \cos^2\theta-1[/tex]
[tex]\implies \cos^2\theta=\dfrac12(\cos 2\theta+1)[/tex]
Then substitute this into the integration.
Please see the attachment for the full integration (it was clearer for me to type this in MS word than use the equation editor here)
Recall the double angle identity for cosines
[tex]{\boxed{\bf{2\cos^{2}(\theta)=1+\cos (2\theta)}}}[/tex]Using this the integral becomes :
[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\{3\cos (\theta)\}^{2}d\theta}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{1}{2}\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}9\cos^{2}(\theta)d\theta}[/tex]
As we can take constant out of the integrand so we have
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{2}\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\cos^{2}(\theta)d\theta}[/tex]
Using the double angle identity for cosines ;
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{2}\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\bigg\{\dfrac{1+\cos (2\theta)}{2}\bigg\}d\theta}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\{1+\cos (2\theta)\}d\theta}[/tex]
Now , as integrals follow distributive property, so we now have
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\bigg(\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}d\theta+\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\cos (2\theta)d\theta \bigg)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\bigg\{\bigg(\theta +\dfrac{\sin (2\theta)}{2}\bigg) \bigg|_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\bigg\}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\bigg[\dfrac{\pi}{2}-\dfrac{\pi}{3}+\dfrac{1}{2}\bigg\{\sin (\pi)-\sin \left(\dfrac{2\pi}{3}\right)\bigg\}\bigg]}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\bigg\{\dfrac{3\pi -2\pi}{6}+\dfrac{1}{2}\bigg(-\dfrac{\sqrt{3}}{2}\bigg)\bigg\}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\bigg(\dfrac{\pi}{6}-\dfrac{\sqrt{3}}{4}\bigg)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{9}{4}\bigg(\dfrac{2\pi -3\sqrt{3}}{12}\bigg)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{3(2\pi -3\sqrt{3})}{4\times 4}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{6\pi -9\sqrt{3}}{16}}[/tex]
[tex]{:\implies \quad \displaystyle \bf \therefore \quad \underline{\underline{\int_{\tiny \dfrac{\pi}{3}}^{\tiny \dfrac{\pi}{2}}\{3\cos (\theta)\}^{2}d\theta =\dfrac{6\pi -9\sqrt{3}}{16}}}}[/tex]

please help me with this , it would mean alot
Answer:
Step-by-step explanation:
21-26. a = v - u / t
=> a = 47 - 19 / 5
=> a = 28 / 5
=> a = 5.6 m/s²
27-32. avg. speed = distance / time
=> 40 m / 10 s
=> 4 m/s
33-38. velocity = distance / time
=> v = 150 / 40
=> v = 15 / 4
=> v = 3.75 m/s

Find the missing side length
Answer:
The missing side length is 36
Step-by-step explanation:
You need to find the ratio of the dilation so if you take corresponding sides, for example, 72 and divide by 8 you get 9. So, if you multiply each side of the triangle XYZ by 9, it should get the length of the sides on triangle ABC.
4 * 9 = 36
Hope this helps! :)
Answer:
36
Step-by-step explanation:
72 is 9 times 8
63 is 9 times 7
36 is 9 times 4

(i) Find percentage of people who donot like both of them.
ii Represent the above information in venn diagram.
The percentage of those that did not like both of them is 76%
Venn diagrams and set notationLet the total number of people in the community be 100%
n(u) = 100
If 58% like to listen to the radio only and 18% like to watch the T.V. only, then;
n(R) = 58 - x
n(T) = 118 - x
where x is the percentage of people who do not like both of them. Taking the sum;
58 + x + 18 = 100
x + 76 = 100
x = 100 - 76
x = 24
Hence 24% of people like both of them.
The percentage of those that did not like both of them is 76%

The train station clock runs too fast and gains 5 minutes every 3 days.
How many minutes and seconds will it have gained at the end of 4 days?
Answer:
first find the average per day. 5/3= 1 & 2/3... 2/3 of a minute is 40 is 60/3=20 seconds. so 4 days would be the full 5 minutes plus another 1 minute and another 40 seconds.. so by day 4 it would be 6 min and 40 seconds.
