Answer:
[tex]x = -1\frac{1}{2}[/tex]
Step-by-step explanation:
Given
See attachment
Required
The x coordinate of P
When point P is traced to the x axis, it lands on -1.5
So:
[tex]x = -1.5[/tex]
Express as fraction
[tex]x = -\frac{3}{2}[/tex]
[tex]x = -1\frac{1}{2}[/tex]
Martina started with 228 boxes of cookies and sold the same number each day for 4 days. After 4 days of selling, she was left with 100 boxes of cookies. Enter the slope of the line representing the change in Martina's inventory of cookies over this period of time.
Answer:
[tex]m = -32[/tex]
Step-by-step explanation:
Let x = days and y = box of cookies
So, we have:
[tex](x_1,y_1) = (0,228)[/tex] -- When she started
[tex](x_2,y_2) = (4,100)[/tex] --- After 4 days
Required
Determine the slope
The slope (m) is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{100 - 228}{4 - 0}[/tex]
[tex]m = \frac{-128}{4}[/tex]
[tex]m = -32[/tex]
The slope is -32

Find the matrix product, if possible.
Answer:
below.
Step-by-step explanation:
The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.
Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.
[ -8 2 2] { 3 }
[ 0 ]
[ -3]
= -8*3 + 2*0 + 2 * -3 = [-30] <-------- Answer.
Note a 1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.
please help me with this question. thank you.

It is not a vertical asymptote because where it intersects the line, it is not at the x-intercepts, no zeros, it ain't an asymptote.
2/5+7/15 in its simplest form
Answer:
13/15
Step-by-step explanation:
First convert the fractions to have a common denominator
2/5 = x/15
Cross multiply
2 × 15 = 5 × x
30 = 5x
Divide both sides by 5 to isolate the variable
30 ÷ 5 = x
6 = x
Plug x into the new fraction
6/15
Now add this to the other fraction
6/15 + 7/15
Only add the numerators. The denominators will remain the same number
6 + 7 / 15
13/15
It cannot be reduced anymore so this is simplest form
Find the measure of CB.
Answer:
I'm Pretty Sure Its 40.
Step-by-step explanation:
Answer:
CB = 20.
Step-by-step explanation:
If the triangle is Isosceles, assuming that <D = <B according to the markings, CB must be 20 since 32 is the greatest side and therefore the hypotenuse, 20 is the smaller side and therefore either opposite or adjacent. Given that two sides must be the same, since CB is opposite of angle D which is congruent to angle B, CB = side opposite of angle B = 20.
what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degree.
Answer:
x ≈ 49.7°
Step-by-step explanation:
Since, the given triangle is an isosceles triangle,
Two sides having measure 17 units are equal.
Opposite angles of these equal sides will be equal.
Measure of the third angle = 180° - (x + x)°
By sine rule,
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22}[/tex] [Since, sin(180 - θ) = sinθ]
[tex]\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}[/tex]
[tex]\frac{1}{17}=\frac{(\text{cos}x)}{11}[/tex]
cos(x) = [tex]\frac{11}{17}[/tex]
x = 49.68°
x ≈ 49.7°

4--9w^2
Can Someone help PLS
Answer:
Step-by-step explanation:
Use the identity: a² - b² = (a + b)(a- b)
4 - 9w² = 2² - (3w²)
= (2 + 3w)(2 - 3w)
f(x) = 3x - 3
g(x) = 4x + 5
find (f+g) (3)
Answer:
23
Step-by-step explanation:
(f + g)(3) = f(3) + g(3)
f(3) = 3(3) - 3 = 9 - 3 = 6
g(3) = 4(3) + 5 = 12 + 5 = 17
Then
(f + g)(3) = 6 + 17 = 23

Solve for x. Round answer to the nearest tenth (0.1).
Answer:
x = 9.9
Step-by-step explanation:
This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.
In this case, multiply. The side measurement of 1 has 7.
1 x 7 = 7
In the same, you must multiply 7 with √2
x = 7 * √2 = 7√2.
√2 = ~1.414
7 x 1.414 = 9.898
Round to the nearest tenth:
9.898 rounded to the nearest tenth = 9.9
x = 9.9
~
Answer:
9.9 is your answer
Step-by-step explanation:
by using Pythagoras law
p²+b²=h²
7²+7²=x²
x=√{2×49)=7√2or 9.9 is your answer

Find the base of a triangle whose altitude is 12 cm and area is 96 cm
Given:
Altitude of a triangle = 12 cm
Area of the triangle = 96 sq. cm
To find:
The base of the triangle.
Solution:
The area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Putting Area = 96 and height = 12, we get
[tex]96=\dfrac{1}{2}\times base\times 12[/tex]
[tex]96=6\times base[/tex]
Divide both sides by 6.
[tex]\dfrac{96}{6}=base[/tex]
[tex]16=base[/tex]
Therefore, the base of the triangle is 16 cm.

A regular pentegon is divided into five identical isosceles triangles. The area of the regular Pentagon is Bcm^2 . Write a formula for T, the area of one of the triangles
Answer:
B/5
Step-by-step explanation:
A regular pentagon has five sides of equal lengths. If each vertex of the regular pentagon is connected to its centre, you would have five identical isosceles triangles.
Hence, the five triangles all have equal areas. If the area of a triangle is Xcm², then
5X = B
X= B/5
