Answer:
154
Step-by-step explanation:
Because since it says find f(7) you plug the 7 into the x's so it would be...
4(7)^2-7(7)+7= 154

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.

How can we find distance of two station when time and speed is given
what is uv + v u = –1 and v = –1.
Answer:
u=1/2
Step-by-step explanation:
if v=-1 then v is multiplying u, -u+ -u which gives -2u. to find u, divide both sides by -2 .-1/-2 the negative cancels the negative giving you positive number, which is 1/2

The perimeter of a rectangle whose length is twice as much as its width, is 30 in. Find its length and width.
Answer:
Width = 5
Length = 10
Step-by-step explanation:
Let x be the width of the rectangle
2x + 2(2x) = 30
x = 5
Width = 5
Length = 10
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°

Carmen needed 23 of a yard of fabric to make a shirt and a 12 yard of fabric to make a matching skirt. How much total fabric did Carmen need to buy? 1 yard of fabric 1 yard of fabric 34 yard of fabric , 3 fourths, yard of fabric 116 yards of fabric , 1 and 1 sixth, yards of fabric 56 yard of fabric
Answer:
38/3 yards
Step-by-step explanation:
Given that,
Fabric required to make a shirt = 2/3 of a yard
Fabric required to make a skirt = 12 yards
Total fabric needed,
[tex]x=\dfrac{2}{3}+12\\\\=\dfrac{38}{3}\ yards[/tex]
Hence, 38/3 yards of fabric is needed.
