Answer:
10ft
Step-by-step explanation:
Answer:
14.4 m
Step-by-step explanation:
let the height of the tower from line of sight be x, then
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{30}[/tex] ( multiply both sides by 30 )
30 × tan23° = x , thus
x ≈ 12.7 m
Total height of tower = 12.7 + 1.7 = 14.4 m ( to the nearest tenth )
Brett deposited $3200 into a savings account for which interest is compounded quarterly at a rate of 2.4%. How much interest will he earn after 15 years? $300.42 $768.14 $1367.19 $1381.72
Answer:
$1,367.19
Step-by-step explanation:
Answer: $1381.72
Step-by-step explanation:
A= P(1+r/n)^nt
(Compounded quarterly= 4)
step 1.
3200(1+0.024/4)^(4)(15):
3200(1+0.006)^60= 4581.72
step 2.
4581.72- 3200= 1381.72

3x+2y=19
-9x+8y=-29
Step-by-step explanation:
(3x + 2y =19)(3)
-9x + 8y =-29
9x + 6y = 57 NOTE: we cross here 9x in first
-9x + 8y = -29 we cross here - 9x in second
Since 9x and - 9x are opposite
___________
6y +8y = 57 - 29
14y = 28
Y=28/14
Y=2
Replace y in second equation of this system:
-9x + 8y = - 29
-9x +8(2)= - 29
-9x + 16 = - 29
-9x = -29 - 16
-9x = - 45
X= -45/-9
X=5

Answer:
902.06 i believe not possitive
Step-by-step explanation:
Answer: 904.78 cm
Step-by-step explanation:
Equation to Sphere: V=4/3 πr*3
Equation to Radius: r=d/2
The diameter is 12 and 12/2=6.
4/3xπ=4.18879020479
6*3=6x6x6=216
216x4.18879020479=904.778684235
Let’s round it to the nearest hundredth though-it’ll be 904.78.

Find the zeros of the function. Enter the solutions from least to greatest.
f(x) = (x - 4)^2 - 25
lesser x=
greater x=
Answer:
In conclusion,
lesser x =−1
greater =9
Step-by-step explanation:
The zeros of the function f(x) = (x - 4)² - 25 are -1 and 9, and the solutions from least to greatest are -1, 9.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find the function's zeros, we need to solve for f(x) = 0.
We can simplify the given function as:
f(x) = (x - 4)² - 25
= (x - 4 + 5) (x - 4 - 5)
= (x + 1)(x - 9)
Now, we can set each factor equal to zero to find the zeros of the function:
x + 1 = 0 or x - 9 = 0
Solving for x in each equation, we get:
x = -1 or x = 9
Therefore,
The zeros of the function f(x) = (x - 4)² - 25 are -1 and 9, and the solutions from least to greatest are -1, 9.

solve the equation x² + 6x + 1 = 0
Answer:
Two solutions were found :
x =(6-√40)/2=3-√ 10 = -0.162
x =(6+√40)/2=3+√ 10 = 6.162
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring x2-6x-1
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is -6 .
-1 + 1 = 0
The solutions to the equation x² + 6x + 1 = 0 are -0.177 and -5.823.
Given:
quadratic equation x² + 6x + 1 = 0
The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the following formula:
[tex]x = \dfrac{-b \pm \sqrt {(b^2 - 4ac)}}{2a}[/tex]
In our equation, a = 1, b = 6, and c = 1.
Now, let's plug these values into the quadratic formula:
[tex]x = \dfrac{-6 \pm \sqrt {(6^2 - 4(1)(1))}}{2(1)}[/tex]
x = (-6 ± √(36 - 4)) / 2
x = (-6 ± √32) / 2
Now, the two solutions for x:
1. x = (-6 + √32) / 2
= (-6 + 5.66) / 2
= -0.177
2. x = (-6 - √32) / 2
= (-6 - 5.66) / 2
-5.823
So, the solutions are -0.177 and -5.823.

what is −5x+4y=3
x=2y−15
Answer:
x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5(2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = -72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2(12) - 15
x = 24 - 15
x = 9
Answer:
x = 9
y = 12

and white striped blanket for her bed.
There are 7 pink stripes and 6 white
stripes. Each stripe is 8 inches wide.
How wide is Alyssa's blanket? Explain.
Answer:
104 Inches
Step-by-step explanation:
Alyssa's blanket contains 7 pink stripes and 6 white stripes.
Total Number of Stripes =7+6=13
Since each stripe is 8 inches wide.
The width of Alyssa's blanket will be the product of the number of stripes by the width of each stripe.
Therefore:
Width = 13 X 8 Inches =104 Inches
Alyssa's blanket is 104 Inches wide.

(y^3- y^2 + y + 3) ÷ (y + 1)
Answer:
(y²- 2y + 3) will be the answer.
Step-by-step explanation:

By using long division method,
y + 1) y³ - y² + y + 3 (y²- 2y + 3
y³ + y²
- 2y² + y
-2y² - 2y
3y + 3

Here the quotient is (y² - 2y + 3) and the remainder is 0.
Therefore, answer will be (y² - 2y + 3).

The cost of 6 sandwiches and 4 drink is $53. The cost of 4 sandwiches and 6 drinks is $47. How much does one sandwich cost?
Answer:
sandwich = 6.50
Step-by-step explanation:
Let s = sandwich price
d = drink price
6s + 4d = 53
4s + 6d = 47
Multiply the first equation by 3
18s + 12d = 159
Multiply the second equation by -2
-4s - 12d = -94
Add these equations together
18s + 12d = 159
-8s - 12d = -94
--------------------------
10s = 65
Divide by 10
s = 65/10
s =6.5
3x+17<47
-6x+9<25
Solve the inequalities and make a number line
Answer: Read below.
Step-by-step explanation:
[tex]3x+17<47\\-6x+9<25[/tex]
Let's take the first one.
[tex]3x+17<47[/tex]
Subtract 17
[tex]3x<47-17\\3x<30[/tex]
Divide by 3
[tex]x<\frac{30}{3}\\ x<10[/tex]
---------------------------------------------------------------------------------------------
Now the second one.
[tex]-6x+9<25\\-6x<25-9\\-6x<16[/tex]
Here's the trick. You need to divide by -6; however, there's a rule. When you multiply or divide by negative numbers, the inequality sign flips.
[tex]x>\frac{16}{-6}[/tex]
[tex]x>-\frac{8}{3}[/tex]
---------------------------------------------------------------------------------------------
x has to be less than 10
x has to be greater than [tex]-\frac{8}{3}[/tex] or -2.66 approximately.
in the number line, make a hollow circle on [tex]-\frac{8}{3}[/tex] and draw an arrow up to [tex]10[/tex] where, again, you have to make a hollow circle. The circles have to be hollow because neither [tex]-\frac{8}{3}[/tex] nor 10 are part of the answers.
