If f (x) = x^2 + 3, evaluate f (-4).
=
A) -5
B) 19
C
11
D) -13
Answer: B) 19
Step-by-step explanation:
To solve this problem, simply plug in -4 for x:
[tex]f(x)=x^{2} +3\\f(x)=(-4)^{2} +3\\f(x)=16+3\\f(x)=19[/tex]
Hope it helps :) and let me know if you want me to elaborate/explain further
Answer:
D. -13
Step-by-step explanation:
If you substitute -4 in for x you get -4^2+3, so when you simplify you get -16+3 which equals -13.
f(x)=x^2+3
f(-4)= -4^2+3
f(-4)= -16+3
f(-4)= -13
Fill in the function table: y = -2(x - 1)
please help
we first substitute the x
y= -2(-2-1)
=6
and then use a calculator to do the sum
which gives us 6
y= -2(-1-1)
= 4
y= -2(0-1)
=2
y= -2(1-1)
=0
y= -2(2-1)
=-2
Find the equation of the line that passes through (1,-2) and is parallel to y = 3x + 4.
Leave your answer in the form y = mx + c
Answer: y=3x-5
Step-by-step explanation: Find the slope of the original line. slope is m=3. Then use the point slope formula [tex]y-y1=m(x-x1)[/tex] to find the line parallel to y=3x+4. Parallel lines have the same slope. so you substitute the given point (x1,y1)(1,-2) and slope m=3 into the point slope formula.
y-(-2)=3(x-1)
y+2=3x-3
y=3x-5

The general equation for a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where the center is (h,k) and the radius is r.
The equation we are given is:
[tex](x-2)^2+(y+3)^2=80[/tex]
From this, the center is (2,-3), and the radius is [tex]\sqrt{80}[/tex], or [tex]4\sqrt{5}[/tex].

Use trig identities to show that sec θ − cos θ = tanθ (sin θ)
Use [tex]\sec\theta = \dfrac{1}{\cos{\theta}}[/tex] to get
[tex]\sec\theta -\cos{\theta}= \dfrac{1}{\cos{\theta}}-\cos(\theta})[/tex]
Then find a common denominator:
[tex]\dfrac{1}{\cos{\theta}}-\cos(\theta}) = \dfrac{1}{\cos{\theta}}-\dfrac{\cos^2\theta}{\cos\theta}[/tex]
But now make that one fraction:
[tex]\dfrac{1}{\cos{\theta}}-\dfrac{\cos^2\theta}{\cos\theta} = \dfrac{1 - \cos^2\theta}{\cos{\theta}}[/tex]
But that's just sin^2 on the top
[tex]\dfrac{1 - \cos^2\theta}{\cos{\theta}} = \dfrac{sin^2\theta}{\cos{\theta}} = \dfrac{sin\theta\cdot sin\theta}{\cos{\theta}}[/tex]
Split that fraction up:
[tex]=\dfrac{ sin\theta}{\cos{\theta}}\cdot sin\theta[/tex]
And tan = sin/cos
[tex]=\tan\theta\cdot sin\theta[/tex]
Watching a Helicopter Take Off At a distance of 58 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 55 ft/sec when it is at an altitude of 113 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.)
The Pythagora´s Theorem, tell us that in a right triangle, the square of the hypothenuse (L²) is equal to :
L² = x² + y²
x and y are the legs.
The solution is
dy/dt = 48.9 ft/s
We know that in a right triangle:
L² = x² + y² (1)
If the helicopter lifts off vertically, that means x ( the horizontal distance between the observing man and the helicopter, maintains constant).
According to that, if we get derivatives with respect to time on both sides of equation (1) we get:
2×L× dL/dt = 0 + 2×y×dy/dt (2)
And
L = √ ( 58)² + ( 113)² = √12769 + 3364 = 127.02 ft
L = 127.02 ft when y = 113 ft
Now in equation (2) we know:
y = 113 ft dy/dt = 55 ft/s L = 127.02 we look for dL/dt
Then by substitution
2×127.02 × dL/dt = 2×113×55
254.04× dL/dt = 12430
dL/dt = 48.92
dL/dt = 48.9 ft/s

Answer:
A = L x W
A = 3 3/4 x 1 1/2
A = (you do the math, 3 3/4 x 1 1/2 : )
Step-by-step explanation:
Hope this helps! Please gie brainliest
Answer:
The formula to find the AREA of a rectangle is as shown A=l x w
L meaning Lenght, which in this case is 3 [tex]\frac{3}{4}[/tex] ft.
W meaning width, which in this case is 1 [tex]\frac{1}{2}[/tex] ft.
Now that you know what the length and the width are, you want to multiply them like the formula A = l x w
A= 3 [tex]\frac{3}{4}[/tex] x 1 [tex]\frac{1}{2}[/tex]
You want to create the fractions into a mixed number.
3 3/4 = 15/4
1 1/2 = 3/2
Now when you multiply it should look like this :
[tex]\frac{15*3 }{4*2}[/tex] or 15x3 / 4x2
This will get you the mixed number of 45/8
Then you can covert the mixed number to a whole number which will be
5 5/8
This will get you the final answer of 5 [tex]\frac{5}{8}[/tex] ft. This is your area.

If 5 bats and 4 balls weigh 58 kg, and 4 bats and 5 balls weigh 50 kg, then how much does a bat weigh?
The bat weighs 10kg.
Two equations can be gotten from the question:
5a + 4b = 58 equation 1
4a + 5b = 50 equation 2
Where:
a = weight of bats
b = weight of balls
The two equations are simultaneous equations and would be solved using the elimination method.
In order to determine the weight of balls, take the following steps:
Multiply equation 1 by 4 and equation 2 by 5
20a + 16b = 232 equation 3
20a + 25b = 250 equation 4
Subtract equation 3 from 4
18 = 9b
Divide both sides of the equation by 9
b = 2kg
In order to determine the weight of bats, take the following steps:
Replace for b in equation 1
5a + 4(2) = 58
5a + 8 = 58
5a = 58 - 8
5a = 50
Divide both sides of the equation by 5
a = 10kg
