Answer:
a) 34.64 inches
b) The TV will not fit inside the TV cabinet
Step-by-step explanation:
Angharad is buying a new 40-inch screen TV (remember that TV screens are measured along the diagonal )
a)If it is 20 inches tall, how wide is the screen ?
We solve using the formula:
Diagonal ² = Width² + Height²
Diagonal = 40 inches
Height = 20 inches
40² = Width² + 20²
Width² = 40² - 20²
Width = √40² - 20²
Width = √(1200)
Width = 34.641016151 inches
Approximately = 34.64 inches
b)Her TV cabinet is 30 inches wide .will the TV fit inside it ?
From the above calculation, the width of the TV = 34.64 inches
Hence the width of the cabinet has to be equal to or more than 34.64 inches
Hence, The TV will not fit inside the TV cabinet
Find all solutions to the equation.
cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
Dennis got 85 percent of the questions on the math test correct, which was out of 40. what was his actual mark?
Answer:
34/40
Step-by-step explanation:
85/100 cross multiply x/40
100x/100=3400/100
x=3400/100
3400/100=34
x=34

Jalen is computing the slope of the line on the graph below.
On a coordinate plane, a line goes through points (negative 4, 0) and (2, 3).
Step 1: (–4, 0) and (2, 3)
Step 2: StartFraction negative 4 minus 2 Over 0 minus 3 EndFraction
Step 3: StartFraction negative 6 Over negative 3 EndFraction
Step 4: The slope is 2.
Which statement describes Jalen’s error?
Jalen computed the ratio of change in x to change in y.
Jalen used the ordered pairs in the wrong order.
Jalen made a computational error.
Jalen used an ordered pair that is not on the line.
Answer:
Jalen used an ordered pair that is not on the lineStep-by-step explanation:
2. Write two numbers that are opposites and each more than 6 units away from 0.
Answer:
-7, 7
Step-by-step explanation:
Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)

Find the fourth term of the
geometric sequence, given the
first term and common ratio.
ay=8 and r=4
[ ? ]
Answer:
Are there options ??
Step-by-step explanation:
12, 17, 22... find the 35th term
Answer:
a₃₅ = 182
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 12 = 22 - 17 = 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 5 , then
a₃₅ = 12 + (34 × 5) = 12 + 170 = 182

Given that (-1,-1) is on the graph of f(x), find
the corresponding point for the function
f(x - 5).
Answer:
(-1, -6)
Step-by-step explanation:
f(x -5) is another way to say f(x) - 5
And f(x) - 5 is going down the y axis 5 points, so you end at (-1, -6)

Write each number in standard form.
6.1 × 104
634.4 so the standard form is 600 + 30 + 4 + 0.4
Answer:
634.4 or 6.344*10^2
Step-by-step explanation:
When you're being asked to write an expression in standard form, the question probably wants you to simplify the expression or write it in scientific notation
Usually, in lower levels, you would simplify the expression, in which case you would multiply 6.1 by 104 using either a calculator (if you're allowed) or on paper to get 634.4
If you think your teacher wants you to use scientific notation, you would want to write your expression as a number under 10 multiplied by a power of 10. For example, if you were looking to write 6*8 in scientific notation/standard form, you would simplify for a product of 48, and turn that into 4.8*10. In your problem, you can multiply 6.1*104, and write your product of 634.4 as 6.344*10^2
please tell me if there are any mistakes in my answer, if i wrote anything poorly, or if anything is hard to understand, i hope this helps!!

What single percentage change is equivalent to a 12% decrease followed by a 18% increase?
Given:
12% decrease followed by a 18% increase.
To find:
The single percentage change is equivalent to the given set of percentages.
Solution:
Let the initial value be 100.
After 12% decrease, the value is:
[tex]v_1=100-\dfrac{12}{100}\times 100[/tex]
[tex]v_1=100-12[/tex]
[tex]v_1=88[/tex]
After 18% increase, the value is:
[tex]v_2=88+\dfrac{18}{100}\times 88[/tex]
[tex]v_2=88+15.84[/tex]
[tex]v_2=103.84[/tex]
The initial value is 100 and the new value in 103.84. So, it represents increase in the value. So, increase percentage is
[tex]Increase\%=\dfrac{\text{New -Initial}}{\text{Initial}}\times 100[/tex]
[tex]Increase\%=\dfrac{103.84-100}{100}\times 100[/tex]
[tex]Increase\%=3.84[/tex]
Therefore, the value increased by 3.84%.
